2 Overview of NonStop TCP/IPv6 This manual documents NonStop TCP/IPv6 only. For information about Parallel Library TCP/IP, see the TCP/IP (Parallel Library) Configuration and Management Manual. Note. Parallel Library TCP/IP is not supported on Integrity NonStop servers. If run in INET mode (see Table 2-5 on page 2-20), NonStop TCP/IPv6 is a direct replacement for Parallel Library TCP/IP.
Overview of NonStop TCP/IPv6 Compatibility Compatibility NonStop TCP/IPv6 coexists with conventional TCP/IP on NonStop S-series servers and on Integrity NonStop servers. An application can have sockets open in both the NonStop TCP/IPv6 and conventional TCP/IP environments. NonStop TCP/IPv6 cannot coexist on the same system as Parallel Library TCP/IP. Note. Parallel Library TCP/IP is not supported on Integrity NonStop servers.

Overview of NonStop TCP/IPv6 Round-Robin Filtering In a single-IP configuration, remote clients trying to connect to the NonStop TCP/IPv6 network only need to know a single IP address to receive the processing power of up to 16 processors. Round-Robin Filtering For multiple processors to share an interface (SLSA LIF), a NonStop TCP/IPv6 feature called round-robin filtering must be enabled.
Overview of NonStop TCP/IPv6 Logical-Network Partitioning (LNP) You can limit the shared ports by adding one or both of the DEFINEs: ADD DEFINE =PTCPIP^FILTER^TCP^PORTS, FILE Pstartport.Pendport ADD DEFINE =PTCPIP^FILTER^UDP^PORTS, FILE Pstartport.Pendport The startport and endport variables are integers specifying the allowable port range. The =PTCPIP^FILTER^TCP^PORTS key limits the shared TCP ports to the range defined in startport and endport.

Ethernet Failover, NonStop Operations Overview of NonStop TCP/IPv6 restrict itself to specific interfaces, has direct access (with no inter-process, messagesystem hop) to the network adapter. The loopback SUBNET is assigned logically to the default LNP, but each LNP can be viewed as having its own copy of the loopback interface. Applications on an LNP use the loopback interface to communicate with other applications on the same LNP without using the local area network as is done in the current product.
NonStop TCP/IPv6 Components Overview of NonStop TCP/IPv6 Table 2-3.
Overview of NonStop TCP/IPv6 TCP6MAN Note that in NonStop TCP/IPv6, the TCP6MON, TCP/IP library and application components are in the data path. Figure 2-8 on page 2-12 also shows that the TCP/IP library is pulled into the application context. Data transfer in the NonStop TCP/IPv6 occurs within the library. The conventional TCP/IP environment shown in Figure 2-8 on page 2-12 requires two message-system, inter-process communication hops.
Overview of NonStop TCP/IPv6 ZTCP6REL/ZTCP6SRL (for G-Series RVUs Only) on page 2-12. As of G06.22, the TCP6SAM process provides a feature from the conventional NonStop TCP/IP product: the ability to associate a TCP/IP process with specific IP addresses and, in turn, to associate applications with that process and set of IP addresses. This feature is called LNP (see Logical-Network Partitioning (LNP) on page 2-8).
Overview of NonStop TCP/IPv6 ZTCP6DLL ZTCP6DLL On Integrity NonStop servers, the functionality of the SRL is replaced by a dynamic linked library (DLL). The DLL requires no configuration steps; use of the DLL is fully automated. PTrace (ZTC6PTR) The PTrace product module formats the trace data records. SCF The SCF product module provides the command-line interface for managing the NonStop TCP/IPv6 subsystem.

Overview of NonStop TCP/IPv6 Programming With the TCP6SAM Socket Provider Programming With the TCP6SAM Socket Provider Applications rely on the transport-service provider for making socket requests. An application programmer can specify either the conventional TCP/IP or the NonStop TCP/IPv6 environment by choosing the appropriate transport-service provider. To select the NonStop TCP/IPv6 environment, see How to Access NonStop TCP/IPv6 on page 2-21.
Overview of NonStop TCP/IPv6 Programming With the TCP6SAM Socket Provider In this example, if you wanted to associate your application with IP address 172.17.215.49, you would select $ZSAM2 or $ZSAM3, then define that TCP6SAM process as the transport-service provider name for your application. For examples of starting applications to use an LNP, see IVB. Prepare to Start the Applications (With LNP) on page 1-21 and VB. Start the Applications (With LNP) on page 1-22.

Finally, the monolithic listening model then uses multi-threading to handle all within the same process creating sockets for the connections.

Maximize the Benefit of the NonStop TCP/IPv6 Architecture Distributor Listening Model In the NonStop TCP/IPv6 environment, with round-robin filtering enabled, you can have multiple copies of the monolithic listener running in different processors, all sharing the same port (shown in Figure 3-2 on page 3-5).
Maximize the Benefit of the NonStop TCP/IPv6 Architecture Distributor Listening Model The distributor model achieves some parallelism and load-balancing because of the use of the multiple, back-end server instances. However, the distributor model is limited by the fact that all data must flow through the distributor to the back-end server processes through PATHSEND. This situation creates a potential bottle-neck in the distributor. Figure 3-3 shows the distributor listener model in conventional TCP/IP.
Maximize the Benefit of the NonStop TCP/IPv6 Architecture Distributor Listening Model The distributor listener model can benefit from the NonStop TCP/IPv6 architecture in two ways: • • You can now run multiple distributor processes in multiple processors bound to the same port with round-robin filtering enabled. This arrangement lets you spread the distributor’s workload over as many processors as required achieving unlimited scalability while presenting a single IP host to the outside world.
Maximize the Benefit of the NonStop TCP/IPv6 Architecture Hybrid Listener Model Configuration Example for the Distributor Listening Model on page 3-17 shows you how to configure this listener model. Hybrid Listener Model This method still has a distributor process using Pathway for managing and loadbalancing server process instances, but it uses the standard listener approach, handing off connections, so that data does not have to flow through the distributor process.
Maximize the Benefit of the NonStop TCP/IPv6 Architecture Broker Listener Model allowing reactive distribution. The servers have direct access to the TCP/IP library in their own processors, eliminating both the remote IPC hops and local IPC hops. All the distributors share the same port and present a single IP host to the outside world. Figure 3-6 shows a configuration (simplified for comparison) with two distributors: one in processor 0 and one in processor 2.

4 Plan Your IPv6 Implementation This section provides ideas for planning your IPv6 implementation. Topics in this section include: • • • • • Obtain IPv6 Addresses Install IPv6-Capable Routers on page 4-2 Configure NonStop Server IPv6 Hosts on page 4-2 Develop an IPv6 Implementation Plan on page 4-3 Port Existing IPv4 Applications on page 4-8 Obtain IPv6 Addresses IPv6 addresses are now being deployed by the regional registries.
Plan Your IPv6 Implementation • • • • Install IPv6-Capable Routers Have your routers advertise new network prefixes and deprecate the old prefixes by setting a lifetime. Change DNS servers to advertise node names and the new addresses. Do not hard code addresses in configuration files because hard coding makes the process more complex and labor intensive. Clear all server caches as appropriate. Install IPv6-Capable Routers This process depends on the hardware vendor you have chosen.
Plan Your IPv6 Implementation Develop an IPv6 Implementation Plan Maximize the Benefit of the NonStop TCP/IPv6 Architecture to understand how to scale your applications, see Round-Robin Filtering on page 2-7. Develop an IPv6 Implementation Plan This subsection provides three scenarios of ways to gradually implement IPv6 in your environment.

(For hosts, the host-to-router tunnel is efficient because it saves the Host A, Host B, and Host C administrators from having to create individual host-to-host tunnels for each destination host.) Intranet-to-Internet Scenario In this scenario, you add a v4/v6 router to your network and use it to communicate with the global Internet. The IPv6 hosts communicate with the v4/v6 router using IPv6.

Plan Your IPv6 Implementation Intranet-to-Internet-to-Intranet Scenario using IPv6. For IPv6 traffic between the v4/v6 routers on each subnet, you configure router-to-router tunnels. Figure 4-3 shows a scenario in which the corporation described in the previous sections wants to connect its corporate network with one of its geographically remote departments to create a VPN. To communicate with Host K, Host A sends the IPv6 packet to Router A.
Plan Your IPv6 Implementation Port Existing IPv4 Applications Port Existing IPv4 Applications The NonStop system provides the basic application programming interfaces (APIs) as defined in RFC 2553. You can use the APIs and the AF_INET6 sockets in your existing applications (or in new applications) to communicate with IPv4 nodes today. Your ported applications will continue to communicate with IPv4 nodes and be ready to communicate with IPv6 nodes.
5 Example Illustrations and Adding Features to the Basic Configuration This section explains the configuration examples in Section 1, Quick Start and shows you how to add more features to those basic examples. This section also shows you how to configure the subsystem in INET and INETD modes and discusses the benefits of NonStop TCP/IPv6 for WAN configurations.

The tunnel is a SUBNET named TUN of TYPE TUNNEL.

Note. If you select the reserved IP address from a LIF on a different adapter, you can replace the adapter without taking down TCP/IP communications. DUAL Mode, Ethernet Failover, Nonshared IP Example 1-9 on page 1-19 shows how to configure a DUAL-mode SUBNET with Ethernet failover, nonshared IP.

Manage the NonStop TCP/IPv6 Subsystem Considerations for Round-Robin Filtering Considerations for Round-Robin Filtering This subsection describes special considerations for round-robin filtering. Port Collision Considerations for Listening Processes When you configure a set of listening processes for round robin, do not allow their primary and backup processors to overlap. That is, if you configure primary and backup listening processes, do so in distinct pairs.
Manage the NonStop TCP/IPv6 Subsystem Fault-Tolerant Operations, Ethernet Failover Guidelines The processes sharing the UDP port should not maintain a context for previous messages because a sequence of messages might not be delivered to the same socket if the port is shared. In fact, with round-robin enabled, a sequence of messages is distributed to each of the port-sharing sockets, in turn.
Manage the NonStop TCP/IPv6 Subsystem Fault-Tolerant Operations, Ethernet Failover Guidelines TCP/IPv6 assigns the outbound traffic to the SUBNET assigned to that IP address. Nonshared IP lets you control the inbound traffic load, forcing the connections to be distributed over the two interfaces presented by the different IP addresses. This is handy when you have limited hardware resources or you want to maximize the use of LIFs. Both LIFs of a failover pair must be cabled to the same network segment.
Manage the NonStop TCP/IPv6 Subsystem QIO Management Considerations Configuration Guidelines These are guidelines to use when configuring NonStop TCP/IPv6 with Ethernet failover: • • • • • • • When selecting the LIF pair for the failover SUBNET pair, you should select LIFs on different adapters. When using Fast Ethernet adapters and Gigabit Ethernet adapters connected directly to Ethernet switches, the failover recovery time can be impacted by the spanning tree feature used in a switch.
Manage the NonStop TCP/IPv6 Subsystem Application Isolation Some constraints affecting NonStop TCP/IPv6 (as well as other QIO clients) include the reduction of QIO memory space to 128 MB when QIO is moved to Kseg2 on the NonStop S-series server. (On the Integrity NonStop server, the QIO memory space in global privileged space is 256 MB.) The available QIO memory space impacts the number of LIFs that you can configure on your system because LIFs use QIO memory.
Manage the NonStop TCP/IPv6 Subsystem Stopping NonStop TCP/IPv6 b. For an IPv6 address, NonStop TCP/IPv6 goes to IPNODES and looks for the address. To cause the socket library to use DNS, delete the TCPIP^HOST^FILE DEFINE. Adding or deleting a DEFINE for the IPNODES file does not affect whether the socket library uses DNS.

Enter these commands at the SCF prompt: ->ABORT PROCESS $ZTS0 ->ABORT PROCESS $ZTCPS1 3.
Manage the NonStop TCP/IPv6 Subsystem Managing the System Configuration Database Managing the System Configuration Database The system configuration database (CONFIG) is part of the NonStop Kernel subsystem on NonStop S-series servers and Integrity NonStop NS-series servers. The conventional TCP/IP subsystem (NonStop TCP/IP) does not participate in the system configuration database, but NonStop TCP/IPv6 does.
Manage the NonStop TCP/IPv6 Subsystem Managing Persistence Managing Persistence You can add a generic process to the system configuration database and define that generic process in such a way that the persistence manager ($ZPM) will restart the generic process whenever the generic process abends, is stopped through TACL, or the system is reloaded. To define the generic process this way, set the STARTMODE to SYSTEM.
Manage the NonStop TCP/IPv6 Subsystem How to Manage TCP6SAM-Dependent Applications Command File for Starting a TCP6SAM Process Because you have to start TCP6SAM processes yourself without the aid of the persistence manager, HP recommends that you create a command file for this purpose. However, before issuing the OBEY command on the file, ensure that your session is still in the subvolume of the SRL file by using the FILEINFO command shown in TACL Commands for Starting a TCP6SAM Process on page 6-15. 1.
Manage the NonStop TCP/IPv6 Subsystem How to Add TCP6MAN as a Generic Process to the System Configuration Database about adding a generic process, see the SCF Reference Manual for the Kernel Subsystem Example 6-3.

Manage the NonStop TCP/IPv6 Subsystem • Managing the ND6HOSTD Process Change STARTMODE to DISABLED. In this case, the generic process ($ZZKRN.#ZZTCP) remains in the system configuration database, but is not started by the persistence manager. In addition, you cannot manually start the generic process ($ZZKRN.#ZZTCP) until the STARTMODE is changed back to SYSTEM or MANUAL.
Manage the NonStop TCP/IPv6 Subsystem Configure the ND6HOSTD Process for Address Resolution You need the ND6HOSTD process only when you want to update the DNS with your automatically generated IPv6 addresses. The ND6HOSTD process requires one INET6 SUBNET and one INET SUBNET to be configured in the system (For more information about DNS-query constraints, see the TCP/IPv6 Migration Guide). The ND6HOSTD process is a Guardian process that you configure the $ZPM persistence manager to start.
Manage the NonStop TCP/IPv6 Subsystem NAME $name Configure the ND6HOSTD Process for Address Resolution Specifies the process name, as recognized by TACL. $name cannot exceed three characters (after the dollar sign). This is because the two-digit processor number is appended to the process name. The recommended value is $ZHD. OUTFILE $device Specifies the output file or process name sent to this process (in the startup message) when it is started. $ZHOME should be specified for $device.
Manage the NonStop TCP/IPv6 Subsystem SAVEABEND ON Configure the ND6HOSTD Process for Address Resolution Specifies whether a saveabend file is created if this process stops abnormally. This attribute overrides the SAVEABEND setting in the PROGRAM file for this process. The value of ON should be specified to automatically create a saveabend file if the process ends abnormally. STARTMODE APPLICATION Specifies when the process is started.
Manage the NonStop TCP/IPv6 Subsystem • • Manage Configuration Errors Each LNP that a ND6HOSTD is run on also requires that at least one DUAL mode SUBNET exist in that LNP so that the ND6HOSTD can communicate with the DNS server.
Manage the NonStop TCP/IPv6 Subsystem Managing LNPs From a systems perspective, the overall processor utilization should be less than in the conventional TCP/IP environment because the number of dispatches and context switches is minimized. Managing LNPs Implementing LNP makes configuring NonStop TCP/IPv6 more complex because each LNP is considered independent of the others, each one must have its static routes configured individually.
Manage the NonStop TCP/IPv6 Subsystem Managing Applications Managing Applications Applications are not affected if LNP is not enabled, however after a SUBNET is configured with the attributes enabling logical-network partitioning all applications running on the TCP/IPv6 subsystem are affected. Coding changes are not needed in an application to support LNP, but how an application is run and perhaps configured can change.
Manage the NonStop TCP/IPv6 Subsystem • • • • • • • • • • • • LNP Guidelines SUBNETs configured as failover pairs must be assigned to the same LNP. A SUBNET can be configured with at most two TCP6SAM processes specified in its LNPTPLIST attribute. Route and ARP entries between LNPs cannot be shared, each is independent. Adding of route and ARP entries requires the use of the SUBNET attribute to assign the entry to a specific LNP.
Manage the NonStop TCP/IPv6 Subsystem • • Strategy for Coexistence With Conventional TCP/IP Special considerations apply for the ND6HOSTD process. See Managing the ND6HOSTD Process on page 6-18. You can add up to 64 SUBNETs to an LNP because you can only have 64 SUBNETs in the NonStop TCP/IPv6 subsystem, if you have 64 SUBNETs in one LNP, the default LNP only has the loopback interface. At the other extreme, you can have 64 LNPs, each with one SUBNET.

7 Troubleshooting Tips for NonStop TCP/IPv6 This section provides some conditions to check if you encounter some problems with your NonStop TCP/IPv6 configuration. Review these suggestions that might pertain to your configuration: • • • Check the adapter configuration and ensure that the SACs are configured with the correct Access List. Ensure that all processors running a TCP6MON process are listed in the Access List.
Troubleshooting Tips for NonStop TCP/IPv6 pair in processors 0 and 1 and another primary and backup TELSERV pair in processors 2 and 3. • • • • • The TCP6SAM process must be in a processor that has a TCP6MON running. Ensure that all primary and backup TCP6SAM processes are configured in processors, which contain a running TCP6MON.
8 SCF Reference for NonStop TCP/IPv6 This section provides information about: • • • The Subsystem Control Facility (SCF) SCF commands available for NonStop TCPIPv6 (To find a command quickly, see Table 8-4 on page 8-10.) The PTrace facility SCF for NonStop TCP/IPv6 SCF provides an operator interface to an intermediate process, the Subsystem Control Point (SCP), which in turn provides the interface to the I/O processes of the various subsystems.
SCF Reference for NonStop TCP/IPv6 Object Types TCP6SAM process resides. To get information about these objects on all configured processors, use the SCF commands for the TCP6MAN process instead. Object Types You can monitor and control the NonStop TCP/IPv6 subsystem by issuing commands that act on one or more NonStop TCP/IPv6 subsystem objects. Each object has an object type and an object name. The object type describes the type of object.
SCF Reference for NonStop TCP/IPv6 ENTRY Object Type Figure 8-1.

TCP6SAM Process Object Hierarchy $PROCESS #SUBNET #ROUTE VST101.vsd Note that there is a pound sign (#) in front of the SUBNET and ROUTE objects for TCP6SAM and there is no intermediate monitor (TCP6MON) object.
SCF Reference for NonStop TCP/IPv6 MONITOR Object Type MONITOR Object Type The MONITOR object (TCP6MON) provides the NonStop TCP/IPv6 environment in a processor. Only one TCP6MON can exist per processor. TCP6MON has the reserved name of $ZPTMn where n is the processor number (hexadecimal) where TCP6MON resides. null Object Type The null object is not an actual object type. The term “null” represents the lack of a specified object.
SCF Reference for NonStop TCP/IPv6 ROUTE Object Type the display is “Program.” A program name of TCP6SAM indicates a NonStop TCP/IPv6 process while a program name of TCPIP indicates a conventional TCP/IP process. To obtain a list of all running NonStop TCP/IPv6 processes, enter the SCF LISTDEV TCPIPV6 command. (This command also gives you a list of the running TCP6MON objects.) Again, the process type (TCP6MON or TCP6MAN) is identified in the program field.
SCF Reference for NonStop TCP/IPv6 SUBNET Object Type SUBNET Object Type The SUBNET is the point of connection between the NonStop TCP/IPv6 and an I/O device. All subnets are associated with the TCP6MAN process. Each SUBNET name must be unique within the system. The name can have at most seven alphanumeric characters. The first character must be a letter. The SUBNET object is also subordinate to the TCP6MON object. A SUBNET is accessible to all TCP6MONs in the system.

Object Naming Convention Summary and Reserved Names Starting Symbol (Required) First Character Requirement First Character Recommendation Character Limit Letter EA 7 Object Type Reserved Names ENTRY None MON #ZPTMx # Letter MON names are assigned automatically.
SCF Reference for NonStop TCP/IPv6 Summary States Object-name templates allow you to specify multiple objects by entering either a single wild-card character, or text and one or more wild-card characters. In the NonStop TCP/IPv6 subsystem, you can use these wild-card characters: * Use an asterisk (*) to represent a character string of undefined length. This example deletes all subnets subordinate to $ZZTCP: SCF> DELETE SUBNET $ZZTCP.*.

SCF Reference for NonStop TCP/IPv6 Entering SCF Commands SCF waits for a command, followed by a carriage return. After the command has been received and processed, SCF displays its prompt for the next command. An SCF command always begins with a keyword identifying the command (such as ADD, ABORT, or ALTER). The keyword is followed by the object specifier, consisting of the object type and the object name, as in this example: SCF> ABORT SUBNET $ZZTCP.*.SN1 Note.
SCF Reference for NonStop TCP/IPv6 IP Address Notation IP Address Notation Several attributes defining the SCF ROUTE and SUBNET objects require the specification of an IP address. In the IPV4 environment, an IP address contains 32 bits. You represent such an IP address by using a text string in dotted decimal format: d.d.d.d where d is the decimal value of an 8-bit octet. For example: 130.28.88.7 In the IPV6 environment, an IP address contains 128-bits.
SCF Reference for NonStop TCP/IPv6 ABORT Command In an IPv6 environment, for example, you can represent the 60-bit hexadecimal prefix 12AB00000000CD3 in any of these ways: 12AB:0000:0000:CD30:0000:0000:0000:0000/60 12AB::CD30:0:0:0:0/60 12AB:0:0:CD30::/60 Note. When you specify an IPv6 address for an SCF attribute, you must enclose the address in quotation marks (““).

A IPv6 Fundamentals This section describes these aspects of IPv6: • • • • IPv6 Internet Addressing Stateless Address Autoconfiguration on page A-11 Neighbor Discovery Protocol on page A-13 How IPv6 Tunnels Work on page A-18 IPv6 Internet Addressing IPv6 internet addresses have 128 bits instead of the 32 bits of IPv4 addresses.
IPv6 Fundamentals Types of Addresses Alternatively, you can use this syntax to represent IPv6 addresses in an environment of IPv4 and IPv6 nodes: x:x:x:x:x:x:d.d.d.d In this case, x is a hexadecimal value of a 16-bit piece of the address (six high-order pieces) and d is a decimal value of an 8-bit piece of address (four low-order pieces) in standard, dotted-quad IPv4 form. For example, these are IPv6 addresses: 0:0:0:0:0:0:13.1.68.3 0:0:0:0:0:FFFF:129.144.52.38 When compressed, these addresses are: ::13.
IPv6 Fundamentals Types of Addresses Figure A-1. Unicast Node Address Node Address 0 127 VST144.vsd This address typically consists of a 64-bit prefix followed by a 64-bit interface ID as shown in Figure A-2: Figure A-2. Prefix and Interface ID Prefix Interface ID 0 127 64 bits 64 bits VST145.vsd An interface ID identifies an interface on a link. The interface ID must be unique on a link, but can also be unique over a broader scope.

Do not use IPv4-compatible IPv6 addresses in the Domain Name System (DNS) or the IPNODES file. The Sockets Library will handle the conversion of these addresses for an application. • IPv4-mapped IPv6 address Used to represent an IPv4 address and to identify nodes that do not support IPv6 (IPv4-only nodes).

This address is assumed to be unique only in the site to which the interface is connected. The format of this address is: Figure A-7. Site-Local Address 1111111011 00.............

Multicast Address Format Flags Scope 11..11 Group ID 0 127 8 bits 4 4 bits bits 112 bits VST151.vsd In the preceding address format, the fields have this definition: • 11111111 Identifies the address as multicast. • Flags Can be either 0000, which indicates a permanently-assigned (well-known) multicast address, or 0001, which indicates a temporary (transient) multicast address. • Scope Indicates the scope of the multicast group.
Address Prefixes IPv6 Fundamentals Address Prefixes Each IPv6 address has a unique pattern of leading bits that indicates its address type. These leading bits are named the format prefix (also referred to as a prefix). Table A-1 lists some of the IPv6 address types and their prefixes. Table A-1.
IPv6 Fundamentals • Address Assignment AAAA query A query for a specified domain name in the Internet class returns all associated AAAA resource records in the response. • IP6.INT domain for looking up a name for a specified address (address-to-name mapping) An IPv6 address is represented in reverse order as a sequence of 4-bit nibbles separated by dots with the suffix .IP6.INT appended. For example, the IPv6 address 4321:0:1:2:3:4:567:89ab has this inverse lookup domain name: b.a.9.8.7.6.5.0.4.0.0.0.

IPv6 Fundamentals Address Lifetimes information with Domain Name System (DNS) servers, these mechanisms provide a path toward network renumbering and provide network administrators with control over the use of network addresses without manual intervention on each host on the network. Address Lifetimes IPv6 addresses are leased to an interface for a fixed (possibly infinite) length of time. Each address has an associated lifetime that indicates how long the address is bound to an interface.
IPv6 Fundamentals Neighbor Discovery Protocol If a node determines that its tentative link-local address is not unique, autoconfiguration stops and manual configuration of the interface is required. To simplify recovery in this case, an administrator should supply an alternate interface identifier that overrides the default identifier in such a way that the autoconfiguration mechanism can then be applied using the new (presumably unique) interface identifier.
IPv6 Fundamentals Neighbor Discovery Protocol How hosts discover the set of address prefixes that define which destinations are on-link for an attached link. (Nodes use prefixes to distinguish destinations that reside on-link from those only reachable through a router.) • Parameter discovery How a node learns such link parameters as the link MTU or such Internet parameters as the hop-limit value to place in outgoing packets.
IPv6 Fundamentals Neighbor Discovery Protocol advertisements contain prefixes that are used for on-link determination and/or address configuration, a suggested hop limit value, and so on. • Neighbor solicitation Sent by a node to determine the link-layer address of a neighbor, or to verify that a neighbor is still reachable through a cached link-layer address. Neighbor solicitations are also used for duplicate address detection. • Neighbor advertisement A response to a neighbor solicitation message.
IPv6 Fundamentals Neighbor Discovery Protocol Neighbor solicitation messages can also determine if more than one node has been assigned the same unicast address. Neighbor unreachability detection detects the failure of a neighbor or the failure of the forward path to the neighbor. Doing so requires positive confirmation that packets sent to a neighbor are actually reaching that neighbor and being processed properly by its IP layer. Neighbor unreachability detection uses confirmation from two sources.
IPv6 Fundamentals Neighbor Discovery Protocol Comparison With IPv4 The IPv6 neighbor discovery protocol corresponds to a combination of the IPv4 protocols ARP, ICMP Router Discovery, and ICMP Redirect. In IPv4 there is no generally agreed upon protocol or mechanism for neighbor unreachability detection, although Hosts Requirements [RFC 1122] does specify some possible algorithms for Dead Gateway Detection (a subset of the problems neighbor unreachability detection tackles).
IPv6 Fundamentals • • • • How IPv6 Tunnels Work Unlike ARP, neighbor discovery detects half-link failures (using neighbor unreachability detection) and avoids sending traffic to neighbors with which twoway connectivity is absent. Unlike IPv4 router discovery, the router advertisement messages do not contain a preference field. The preference field is not needed to handle routers of different stability; the neighbor unreachability detection will detect dead routers and switch traffic to a working one.

D NonStop TCP/IPv6 Protocols and Configuration Files This appendix provides background information about networking and material required for configuring the NonStop TCP/IPv6 subsystem.
NonStop TCP/IPv6 Protocols and Configuration Files Transmission Control Protocol (TCP) Transmission Control Protocol (TCP) The Transmission Control Protocol (TCP) is used by applications that require reliable end-to-end data transfer. It is a stream-oriented protocol that has no concept of packet boundaries. TCP guarantees that all data sent will be received and will arrive in the same order in which it was sent.
NonStop TCP/IPv6 Protocols and Configuration Files Internet Protocol (IP) As for TCP, (described in Transmission Control Protocol (TCP) on page D-2), application processes call a socket routine to request the NonStop TCP/IPv6 software to create a UDP socket when needed; the application specifies the type of service desired. The TCP and UDP protocols assume that the Internet Protocol (IP) is used for network layer services. Like IP, UDP is a connectionless protocol; it uses datagrams.
NonStop TCP/IPv6 Protocols and Configuration Files Raw Sockets Raw Sockets As for TCP and UDP, described earlier, application processes call a socket routine to request the NonStop TCP/IPv6 software to create a raw socket when needed. A raw socket provides direct access to the IP. Raw sockets allow applications to take advantage of protocol features not directly accessible through the TCP or UDP interfaces. Applications also can develop new protocols by using raw sockets.
NonStop TCP/IPv6 Protocols and Configuration Files Address Resolution Protocol (ARP) manually a static default route to the specific IP address of the router. If the router's IP address changes, the configuration files on the NonStop machine must change also. With IRDP, there is no need to change any configuration files other than initially enabling the IRDP feature.
NonStop TCP/IPv6 Protocols and Configuration Files Subnetwork Access Protocol (SNAP) that effectively hides physical addresses and allows the IP to use 32-bit Internet addresses. Figure D-1 shows ARP’s relationship to the Ethernet and Internet protocols. Figure D-1. Address Resolution Protocol Ethernet 48-Bit Address ARP Translation Internet 32-Bit Address VST033.vsd The caller (host A) broadcasts a special packet addressed to the receiver’s Internet address (host B).

NonStop TCP/IPv6 Protocols and Configuration Files TCP/IP Configuration Files TCP/IP Configuration Files There are several files that come on your system update tape (SUT) that are used for configuring your Internet environment. You need to customize some of these files to match your own environment.
NonStop TCP/IPv6 Protocols and Configuration Files HOSTS File Consider the example that follows: # HOSTS file 127.0.0.1 me loop geoff mark cyclone # \CB2 is the gateway between subnets for \ENC1 and \CB1 128.1.1.1 CB21 cb21 # on subnet 1.0, lan01 08008E0002A6 128.1.2.1 CB22 cb22 # on subnet 2.0, lan02 08008E000B2D # Notice that the first entry beginning with 127.0.0.1 has several aliases.
NonStop TCP/IPv6 Protocols and Configuration Files IPNODES File Sample HOSTS File: SMPLHOST The site update tape (SUT) comes with a sample HOSTS file that is installed into $SYSTEM.ZTCPIP. The name of this file is SMPLHOST and the contents are shown in the display: 127.54.12.203 127.54.12.208 127.54.12.209 127.0.0.1 dummy1 loghost dummy2 dummy3 localhost me Modify this file for your environment. IPNODES File The IPNODES file contains information regarding the known IPv6 (and IPv4) nodes on the network.

Network addresses, both IPv4 and IPv6, are converted to binary format by using the inet_pton() routine from the NonStop Guardian or NonStop Open System Services (OSS) sockets library.
NonStop TCP/IPv6 Protocols and Configuration Files NETWORKS File Using the Domain Name resolver is the preferred way of resolving names on the network. If a name server is not available on the network, use a HOSTS or IPNODES file, as described earlier. Note. All DNS name servers listed in the RESCONF file must have IPv4 addresses. Name servers with IPv6 addresses are not supported. Sample RESCONF File: SMPLRESC The site update tape (SUT) comes with a sample RESCONF file that is installed into $SYSTEM.
NonStop TCP/IPv6 Protocols and Configuration Files PROTOCOL File Sample NETWORKS File: SMPLNETW The site update tape (SUT) comes with a sample NETWORKS file that is installed into $SYSTEM.ZTCPIP. The name of this file is SMPLNETW and the contents are shown in the display: # # Network configuration file # loopback 127 xxx-ether 192.9.200 tdm-oldether 125 # # Internet networks # arpanet 10 ucb-ether 46 xxxether ethernet localnet tdmoldether arpa ucbether Modify this file for your environment.
NonStop TCP/IPv6 Protocols and Configuration Files SERVICES File Sample PROTOCOL File: SMPLPROT The site update tape (SUT) comes with a sample PROTOCOL file that is installed into $SYSTEM.ZTCPIP. The name of this file is SMPLPROT and the contents are shown in the display: # # @(#)protocols 1.

NonStop TCP/IPv6 Protocols and Configuration Files PORTCONF File You may need to edit the SERVICES file for the DSM/SCM Planner Interface to work. For more information, see the G06.nn Software Installation and Support Guide or the H06.nn Software Installation and Support Guide. PORTCONF File The PORTCONF file specifies the ports that the LISTNER process listens to and the corresponding server program it invokes when the request comes in. Here is an example of the PORTCONF file: # ftp $system.ztcpip.
E Domain Name Server (DNS) This appendix describes DNS 4.x on the NonStop server. Topics include: • • DNS Overview Domain Name Resolver on page E-3 For information about DNS 9.x on the NonStop server, see the DNS Configuration and Management Manual and the BIND 9 Administrator Reference Manual. DNS Overview DNS serves as the yellow pages and white pages of an internet community. It provides the translation and mapping of human-readable machine names into IP addresses.
Domain Name Server (DNS) Types of Domain Name Servers For more information on domain names, refer to RFC 1034 and RFC 1035 available from the DDN Network Information Center. Also, refer to the book TCP/IP Illustrated by W. Richard Stevens, Prentice Hall, 1994. The Domain Name Server (DNS) was ported from BSD BIND 4.8. Note. You should read RFCs 819, 920, 974, 1032, 1033, 1034, 1035, and 1101 before you attempt to configure the server.
Domain Name Server (DNS) Remote Server Remote Server A remote server is an option given to people who would like to use a domain name server on their workstation or on a machine that has a limited amount of memory and CPU cycles. By using this option you can run all the networking programs that use the domain name server without having to run the domain name server on the local machine. All queries are serviced by a domain name server running on another machine on the network.
Domain Name Server (DNS) Domain Name Resolver The resolver uses information specified in a configuration file to provide access to a name server. The default name for this file is $SYSTEM.ZTCPIP.RESCONF. When an application sends a name_resolution request to the resolver, the resolver sends the request to the servers listed in the RESCONF file in order of their priority in a timed sequence. The server listed first in the RESCONF file (the primary server) has the highest priority.
Glossary This glossary defines terms used both in this manual and in other NonStop TCP/IP manuals. Both industry-standard terms and HP terms are included. address. An IP-layer identifier for an interface or a set of interfaces. See also, deprecated address, preferred address, valid address, and invalid address. address mask. A bit mask used to select bits from an Internet address for subnet addressing.
Glossary autonomous system autonomous system. A collection of gateways and networks that fall under one administrative entity and cooperate closely to propagate network reachability (and routing) information among themselves using an interior gateway protocol of their choice. Gateways within an autonomous system have a high degree of trust. At least one gateway in an autonomous system must advertise networks in that system to a core gateway using EGP. baseband.
Glossary Class D Class D. A Class D address is a 4-octet multicast group address. The four high-order bits of the address are always 1110; therefore, the first octet is a number in the range 224 through 239 (%HE0 through %HEF). This means that an Internet can have a total of 268,435,456 multicast groups. collector. An EMS process that accepts event messages from subsystems and logs them in the event log. See also Event Management Service (EMS). Compare distributor. command message.
Glossary control and inquiry subsystem sends a response message that does not contain a context token, the series of response messages is complete. control and inquiry. In DSM, those aspects of object management that affect the state or configuration of an object, such as inquiries about the object and commands pertaining to the environment (for example, commands that set default values for the session). Compare event management. critical event.
Glossary deprecated address derived from the DDL definition file. Likewise, each subsystem that has a tokenoriented programmatic interface has one definition file for DDL and one for each programming language. Some subsystems—for instance, data communications subsystems—have additional, shared definition files. See also SPI standard definitions, data communications standard definitions, or EMS standard definitions. deprecated address.
Glossary empty response record empty response record. In DSM programmatic interfaces, a response record containing only a return token with a value that means “no more response records.” See also return token. EMS . See Event Management Service (EMS). EMS standard definitions. The set of declarations provided by EMS for use in event management, regardless of the subsystem. Any application that retrieves tokens from event messages needs the EMS standard definitions. See also definition or definition files.
Glossary event log event log. A file or set of files maintained by EMS to store event messages generated by subsystems. Event Management Service (EMS). A part of DSM used to provide event collection, event logging, and event distribution facilities. It provides for different event descriptions for interactive and programmatic interfaces, lets an operator or application select specific event-message data, and allows for the flexible distribution of event messages within a system or network.
Glossary FDDI FDDI. See Fiber Distribution Data Interface (FDDI). FESA. See Fast Ethernet ServerNet adapter (FESA). Fiber Distribution Data Interface (FDDI). An emerging standard for a network technology based on fiber optics. FDDI specifies a 100-mbps data rate using 1300-nanometer light wavelength, and limits networks to approximately 200 km in length, with repeaters every 2 km or less. The access control mechanism uses token-ring technology. File Transfer Protocol (FTP).
Glossary GESA normal circumstances, all GGP participants reach a steady state in which the routing information at all gateways agrees. GESA. See Gigabit Ethernet ServerNet adapter (GESA). GGP. See Gateway-to-Gateway Protocol. Gigabit Ethernet 4-port ServerNet adapter (G4SA). A multiport ServerNet adapter that provides 1000 megabits/second (Mbps) data transfer rates between HP NonStop™ S-series systems and Ethernet LANs.
Glossary hierarchical routing specified set of header tokens; event messages, a different set with some overlap. See also SPI message. hierarchical routing. Routing based on a hierarchical addressing scheme. Most Internet routing is based on a two-level hierarchy in which an Internet address is divided into a network portion and a host portion. Gateways use only the network portion until the datagram reaches a gateway that can deliver it directly.
Glossary Institute of Electrical and Electronics Engineers (IEEE) Institute of Electrical and Electronics Engineers (IEEE). An international industry group that develops standards for many areas of electrical engineering and computers. interactive command. In DSM, a command entered by a human operator rather than by a program. See also programmatic command. interface. A node's attachment to a link. This is equivalent to a subnet object within the TCP/IPv6 subsystem and a LIF in the SLSA subsystem.
Glossary interoperability interoperability. The ability of software and hardware on multiple machines from multiple vendors to communicate meaningfully. invalid address. An address that is not assigned to any interface. A valid address becomes invalid when its valid lifetime expires. Invalid addresses should not appear as the destination or source address of a packet.
Glossary Level 2 Level 2. A reference to LINK LEVEL communication (for example, frame formats) or linklevel connections derived from the ISO 7-layer reference model. For long-haul networks, level 2 refers to the communication between a host computer and a network packet switch (for example, HDLC/LAPB). For local area networks, level 2 refers to physical packet transmission. Therefore, a level 2 address is a physical hardware address. Level 3.
Glossary media access control (MAC) address media access control (MAC) address. A MAC address is a value in the Medium Access Control sublayer of the IEEE/ISO/ANSI LAN architecture, that uniquely identifies an individual station that implements a single point of physical attachment to a LAN. management applications. In DSM, an application process that opens a management or subsystem process to control a subsystem.
Glossary noncritical event were local. The key advantage of NFS over conventional file transfer protocols is that NFS hides the differences between local and remote files by placing them in the same name space. NFS is used primarily on UNIX systems, but has been implemented for many systems, including personal computers like an IBM PC and Apple Macintosh. noncritical event. A DSM event not too crucial to system or network operations.
Glossary packet two systems, the services required to perform these functions, and the protocols associated with these services. packet. The unit of data sent across a packet switching network. While some Internet literature uses it to refer specifically to data sent across a physical network, other literature views the Internet as a packet switching network and describes IP datagrams as packets. Packet Internet Groper (PING).
Glossary process process. A running entity that is managed by the operating system, as opposed to a program, which is a collection of code and data. When a program is taken from a file on a disk and run in a processor, the running entity is called a process. programmatic command. In DSM, a command issued by a program rather than by a human operator. Compare interactive command. protocol. A formal description of message formats and the rules two or more machines must follow to exchange those messages.
Glossary SCF SCF. See Subsystem Control Facility (SCF). SCP. See Subsystem Control Point (SCP). secondary route. For multiple routes to the same destination, all the routes in addition to the primary route (the route visible to Radix Routing topology) are called shadow/secondary routes. Also called shadow route on page -18. sensitive command. In DSM, a command that can be issued only by a restricted set of Guardian users, such as the owner of a subsystem process.
Glossary Simple Mail Transfer Protocol (SMTP) Simple Mail Transfer Protocol (SMTP). The Internet standard protocol for transferring electronic mail messages from one machine to another. SMTP specifies how two mail systems interact, and specifies the format of control messages the two mail systems exchange to transfer mail. simple token.
Glossary subnetwork Internet portion and local portion. Gateways and hosts inside a site using subnet addressing interpret the local portion of the address by dividing it into a physical network portion and host portion. subnetwork. One or more intermediate systems that provide relaying and through which end open systems can establish network connections. Subnetwork Access Protocol (SNAP).
Glossary summary state summary state. In DSM interfaces to HP data communications subsystems, one of the generally defined possible conditions of an object, with respect to the management of that object. A summary state differs from a state in two ways. First, a summary state pertains to the management of an object, whereas a state can convey other kinds of information about the object.
Glossary token ring token ring. 1)The token access procedure used on a network with a sequential or ring topology. (2) A data link level protocol designed to transfer data over ring-oriented LANs. The token ring technique is based on the use of a particular bit pattern called a token that circulates around the ring when all stations are idle. token type. In DSM programmatic interfaces, the part of a DSM token code that identifies the data type and length of the token value.
Glossary WAN subsystem WAN subsystem. See wide area network (WAN) subsystem. Warning. In DSM interfaces, a condition encountered in performing a command or other operation, that can be significant but does not cause the command or operation to fail. A warning is less serious than an error. Compare error. well-known port. Any of a set of protocol ports preassigned for specific uses by transport level protocols (that is, TCP and UDP).
Glossary See WAN manager process.
