An Introduction to IP Routing Protocols This chapter provides an introduction to IP routing and IP routing protocols used in the Nortel Ethernet Routing Switch 5500 Series. Subsequent chapters will provide a more detailed description of switch capabilities and configuration procedures. IP routing To configure IP routing on the Nortel Ethernet Routing Switch 5500 Series, use virtual local area networks (VLAN) to create virtual router interfaces by assigning an IP address to the VLAN.
An Introduction to IP Routing Protocols Class Address Range D 224.0.0.0 239.255.255.254 Mask Number of Networks Nodes per Network Note: Class D addresses are primarily reserved for multicast operations although the addresses 224.0.0.5 and 224.0.0.6 are used by OSPF and 224.0.0.9 is used by RIP. E 240.0.0.0 240.255.255.255 Note: Class E addresses are reserved for research purposes.
IP routing 15 A subnet address is created by increasing the network portion to include a subnet address, thus decreasing the host portion of the IP address. For example, in the address 128.32.10.0, the network portion is 128.32, while the subnet is found in the first octet of the host portion (10). A subnet mask is applied to the IP address and identifies the network and host portions of the address.
An Introduction to IP Routing Protocols Variable-length subnet masking (VLSM) is the ability to divide an intranet into pieces that match network requirements. Routing is based on the longest subnet mask or network that matches. IP routing using VLANs The Nortel Ethernet Routing Switch 5500 Series supports wire-speed IP routing between virtual LANs (VLAN). This type of routing is also referred to as virtual routing.
IP routing 17 As with any IP address, virtual router interface addresses are also used for device management. For management over IP, any virtual router interface IP address can be used to access the switch as long as routing is enabled. When the Nortel Ethernet Routing Switch 5500 Series switch or stack is used without routing enabled, the Management VLAN is reachable only through the switch or stack IP address.
An Introduction to IP Routing Protocols Network with Multinetting You can configure a static route with the next hop on the secondary interface. You can also add static ARP for a given IP address in the same subnet of a secondary interface.
IP routing 19 If secondary interfaces are configured on the management VLAN, routing cannot be disabled globally or on the management VLAN.
An Introduction to IP Routing Protocols Management VLAN Prior to Software Release 4.0, the Management VLAN was the only VLAN that was used to carry the management traffic, including Telnet, Web, SNMP, BootP and TFTP for the switch. The Management VLAN always exists on the switch and cannot be removed. All IP settings, including switch IP address, stack IP address, subnet mask and default gateway, apply only to the Management VLAN.
IP routing Step Action 1 Enable IP routing globally. 2 Assign an IP address to the specific VLAN or brouter port. 3 Enable IP routing on the interface. 21 —End— Refer to subsequent chapters in this document for detailed instructions on configuring IP routes. Address Resolution Protocol (ARP) Address Resolution Protocol (ARP) Network stations using the IP protocol need both a physical address and an IP address to transmit a packet.
An Introduction to IP Routing Protocols Proxy Address Resolution Protocol (Proxy ARP) Proxy ARP allows a network station to respond to an ARP request from a locally attached host or end station for a remote destination. It does so by sending an ARP response back to the local host with its own MAC address of the network station interface for the subnet on which the ARP request was received. The reply is generated only if the switch has an active route to the destination network.
IP routing 23 Non-local static routes The Nortel Ethernet Routing Switch 5500 Series supports the usage of non-local static routes. A non-local static route is almost identical to a static route with the exception that the next hop of the route is not directly connected to the network entity. Non-local static routes are useful in situations where there are multiple paths to a network and the number of static routes could be reduced by using only one route with a remote gateway.
An Introduction to IP Routing Protocols 3. The neighbors will send their routing tables and the new router will update its routing table based on the advertisements received. 4. From now on periodic updates are send by each router in the network to ensure a correct routing database. If a router does not receive an update from another router within a timeout period, it deletes the routes served by the nonupdating router from its routing table.
IP routing • subnet mask (RIP version 2) • routing table update based on the received RIP message • global update timer • holddown timer and timeout timer per device and per interface • cost per device and per interface 25 The Nortel Ethernet Routing Switch 5500 Series implementation of RIP also supports the following features: • in and out routing policies • auto-aggregation (also known as auto-summarization) of groups of adjacent routes into single entries Many RIP features are configurabl
An Introduction to IP Routing Protocols RIP Send and Receive Modes RIP can be configured to use a number of different send and receive modes depending on the specifics of the network configuration. The following table lists the send and receive modes supported. RIP send and receive modes Send Mode Description Result rip1comp This mode is used to broadcast RIP version 2 updates using RFC 1058 route consumption rules. This is the default send mode for the Nortel Ethernet Routing Switch 5500 Series.
IP routing rip1OrRip2 RIP version 1 or RIP version 2 updates are accepted. rip1 RIP version 1 and RIP version 1 compatible updates only are accepted. rip2 RIP version 2 updates only are accepted. 27 Limitations RIP has the following limitations: • The protocol is limited to networks whose longest path is 15 hops. • The protocol depends on counting to infinity to resolve certain unusual situations.
An Introduction to IP Routing Protocols Benefits Benefits in large networks OSPF offers the following benefits: • Fast convergence In the event of topological changes, OSPF recalculates routes quickly. • Minimal routing protocol traffic Unlike distance vector routing protocols such as RIP, OSPF generates a minimum of routing protocol traffic. • Load sharing OSPF provides support for equal-cost multipath routing.
IP routing 29 8. From this database each router calculates a shortest-path tree, with itself as root. This shortest-path tree in turn yields a routing table for the protocol. OSPF router types Routers in an OSPF network can take on different roles depending their configuration. The following table describes the router types in an OSPF network.
An Introduction to IP Routing Protocols Host routes are managed with Nortel Networks Command Line Interface (NNCLI) commands and SNMP MIBs and are identified by the host IP address and the configured route type of service (TOS). For each host directly connected to the router, configure the cost of the link to the host during host creation. You cannot modify this cost. Note: Always set TOS to 0 because TOS-based routing is not supported.
IP routing 31 Creating Host Route Example : 1 R3(config)#router ospf R3(config-router)#host-route 11.11.11.111 metric 10 R3(config-router)#show ip ospf host-route Host IP Metric 11.11.11.111 10 R3(config-router)# The following is an example for deleting a host route: Deleting Host Route Example : 1 R3(config-router)#no host-route 11.11.11.
An Introduction to IP Routing Protocols Virtual link diagram Note: Stub or NSSA areas cannot be transit areas. A virtual link can be created manually or automatically. Manual virtual link creation can conserve resources and provide specific control of virtual link placement in the OSPF configuration. To add a virtual link manually, configure both endpoint ABRs with a neighbor router ID and transit area ID. You can configure up to 16 virtual links.
IP routing 33 In this case, R4 in Area2 cannot be physically connected to Area0 (for some reason) and it will be connected to R3 which is NOT a backbone ABR (like R1 is for instance). As Area2 is not directly connected to backbone Area0 or directly connected to a backbone ABR router, clients from Area2 will not be able to access anything outside Area2. Also, router R3 is an ABR router connected to two non-backbone areas.
An Introduction to IP Routing Protocols OSPF Traps: Disabled Auto Virtual Link Creation: Enabled SPF Hold-Down Time: 10 RFC 1583 Compatibility: Enabled R3 (config-router)#auto-vlink Example : 2 R3(config)#show ip ospf Router ID: 3.0.1.
IP routing 35 Router ID: 3.0.1.
An Introduction to IP Routing Protocols Route policies supports the following types of policies: • Accept (In) Policies Accept polices are applied to incoming routing updates before they are applied to the routing table. In the case of RIP, accept policies can be applied to all incoming packets and only one policy can be created for each RIP interface. In the case of OSPF, accept policies are only applied to Type 5 External routes based on the advertising router ID.
IP routing 37 To configure routing policies, create the appropriate prefix lists and then assign those prefix lists to route maps. Once all route maps have been created, assign them to the appropriate type of policy. In a stacked environment, the following rules are applied to routing policies: • The policy database is stored in all stack units. • Policy configuration is supported from only the base unit. The base unit sends updates to non-base units to update the policy database in each stack unit.
An Introduction to IP Routing Protocols Equal Cost MultiPath (ECMP) The Equal Cost MultiPath (ECMP) feature allows routers to determine equal cost paths to the same destination prefix. The multiple paths can be used for load sharing of traffic and allows faster convergence to other active paths in case of network failure. By maximizing load sharing among equal-cost paths, links between routers can be used more efficiently when sending IP traffic.
IP routing 39 For each ingress interface and protocol, the UDP broadcast packets are forwarded only to a unicast host address (the unicast IP address of the server for example). Dynamic Host Configuration Protocol (DHCP) / Bootstrap Protocol (BootP) DHCP-BootP relay The Dynamic Host Configuration Protocol (DHCP) is an extension of the Bootstrap protocol (BootP) and provides host configuration information to workstations on a dynamic basis.
An Introduction to IP Routing Protocols "DHCP operation" (page 40)Figure DHCP operation shows an end station connected to subnet 1, corresponding to VLAN 1. The Nortel Ethernet Routing Switch 5500 Series connects two subnets by means of the virtual routing function. When the end station generates a DHCP request as a limited UDP broadcast to the IP address of all 1s (that is, 255.255.255.
IP routing 41 If a DHCP client is connected to a routable interface, to configure DHCP requests to be sent to up to 512 different routable interfaces or 512 different server IP addresses, enable DHCP on the client (agent address) and then enable DHCP from the client to each of the interfaces or IP addresses (server addresses). In the example shown in "Multiple BootP/DHCP servers" (page 41), two DHCP servers are located on two different subnets.
An Introduction to IP Routing Protocols Any of the Nortel Ethernet Routing Switch 5500 Series switch management systems can be used to set DHCP. DHCP relay DHCP (Dynamic Host Configuration Protocol) is a mechanism to assign network IP addresses to clients who request an address. It is built on top of the existing BOOTP protocol and can be specified for DHCP, BOOTP, or both. The DHCP relay feature relays client requests to DHCP servers on different L3 VLANs.
IP routing 43 These commands must be executed in the Global Configuration command mode. Interface DHCP relay configurations These configurations are associated with the L3 VLAN that the client or server resides on. IP routing must be enabled and a valid IP address must be assigned to the L3 VLAN before it generates the default settings for DHCP relay. "Interface DHCP relay commands" (page 43)describes the interface DHCP relay commands.
An Introduction to IP Routing Protocols DHCP relay uses a hardware resource that is shared by switch Quality of Service applications. When DHCP relay is enabled globally, the Quality of Service filter manager will not be able to use precedence 11 for configurations. For the filter manager to be able to use this resource, DHCP relay must be disabled for the entire unit or stack.
IP routing 45 IP blocking IP Blocking is a Layer 3 feature of the Nortel Ethernet Routing Switch 5500 Series that provides built-in safeguards for the usage of duplicate IP addresses in a stacked environment. IP Blocking is used whenever a unit leaves a stack or is rebooting inside the context of a stack. Depending on the setting in use, Layer 3 functionality is either continued or blocked by this feature. IP Blocking can exist in either a none or full condition.
An Introduction to IP Routing Protocols — The stack will continue to run normally with the base unit controlling Layer 3 and DRP functionality. — If the non-operational non-base unit does not rejoin the stack, no Layer 3 or DRP functionality will run on it.
IGMP snooping 47 "IP multicast propagation with IGMP routing" (page 47)shows how IGMP is used to set up the path between the client and server. As shown in this example, the IGMP host provides an IP Multicast stream to designated routers that forward the IP Multicast stream on their local network only if there is a recipient. The client/server path is set up as follows: 1.
An Introduction to IP Routing Protocols The Nortel Ethernet Routing Switch 5500 Series can automatically set up IP Multicast filters so the IP Multicast traffic is only directed to the participating end nodes (see ). In , "5500 Series switch filtering IP multicast streams (1 of 2)" (page 48)switches S1 to S4 represent a LAN connected to an IP Multicast router. The router periodically sends Host Membership Queries to the LAN and listens for a response from end stations.
IGMP snooping 49 5500 Series switch filtering IP multicast streams (2 of 2) The consolidated proxy report generated by the switch remains transparent to Layer 3 of the International Standardization Organization, Open Systems Interconnection (ISO/OSI) model. (The switch IP address and MAC address are not part of proxy report generation.) The last reporting IGMP group member in each VLAN represents all of the hosts in that VLAN and IGMP group.
An Introduction to IP Routing Protocols • The snooping field must be enabled for the proxy field to have any valid meaning. • Static router ports are configured per VLAN and per IGMP Version. Note: Because IGMP snooping is set up per VLAN, all IGMP changes are implemented according to the VLAN configuration for the specified ports.

IP Routing Configuration and Management 5530-24TFD(config-if)# ip rip receive version rip2 —End— Using RIP accept policies RIP accept policies are used on the Nortel Ethernet Routing Switch 5500 Series to selectively accept routes from RIP updates. If no policies are defined, the default behavior is applied. This default behavior is to add all learned routes to the route table. RIP accept policies are used to: • Listen to RIP updates only from certain gateways.
IP routing configuration examples 131 Accept policy configuration Use the following steps to recreate the above configuration example: Step Action 1 Configure the IP prefix list on ERS1. Create a prefix list named Prefix_1 with an IP range from 10.1.240.0 to 10.1.255.0. 5530-24TFD(config)# ip prefix-list Prefix_1 10.1.240.0/20 ge 20 le 32 2 Configure the route policy named rip_pol_1 with match criteria using the IP prefix configured in step 1.

IP routing configuration examples 135 To create the OSPF interface illustrated above for router R1, follow this procedure: Step Action 1 Configure brouter port OSPF interface. Configure port 2 as a brouter port with VLAN ID of 2134 and enable OSPF on this interface. 5530-24TFD# config terminal 5530-24TFD(config)# interface fast 2 5530-24TFD(config-if)# brouter port 2 vlan 2134 subnet 10.1.1.21/30 5530-24TFD(config-if)# router ospf 5530-24TFD(config-router)# network 10.1.1.
IP Routing Configuration and Management Simple password mechanism The simple password security mechanism transmits a text password in the OSPF headers. Only routers that contain the same authentication ID in their OSPF headers can communicate with each other. Note: Nortel recommends not using this security mechanism because the password is stored in plain text and can be read from the configuration file or from the OSPF packet.
IP routing configuration examples 137 MD5 configuration example To replicate the above configuration example using the key ID 2 and key value qwsdf89, perform the following steps: Step Action 1 Configure MD5 authentication on R1. 5530-24TFD(config)# interface vlan 2 5530-24TFD(config-if)# ip ospf message-digest-key 2 md5 qwsdf89 5530-24TFD(config-if)# ip ospf primary-md5-key 2 5530-24TFD(config-if)# ip ospf authentication-type message-digest 2 Configure MD5 authentication on R2.

IP routing configuration examples 139 The impact of a topology change is localized to the area in which it occurs. The only exception to this is for the area border routers, which must maintain an LSDB for each area to which they belong. Changes in topology are advertised to the rest of the network by the area border routers by advertising summary LSAs. A 32-bit Area ID, expressed in IP address format such as 0.0.0.0 for 0 identifies areas.
IP Routing Configuration and Management Stub and Not So Stubby areas Stub areas do not receive advertisements for external routes (AS-external LSAs, type 5) from an ABR, which reduces the size of the link state database. Instead, routing to external destinations from within a stub area is based on the default route that is originated by the stub area ABR (Summary LSA, type 3).
IP routing configuration examples 141 OSPF stub area example Note: AS-external LSAs are not flooded into a stub area. Instead, only one default route to external destinations is distributed into the stub area by the stub ABR router. The area default cost specifies the cost for advertising the default route into stub area by the ABR. Use the procedure outlined below to perform the stub area configuration illustrated above: Note: This example assumes that global IP routing has been enabled on the switch.
IP Routing Configuration and Management Configure R1 in stub area 2 with the Router-ID 1.1.1.5. Add the OSPF interfaces to area 2 and enable OSPF on these interfaces. 5530-24TFD(config-router)# 5530-24TFD(config-router)# noexternal 5530-24TFD(config-router)# 0.0.0.2 5530-24TFD(config-router)# 0.0.0.2 5530-24TFD(config)# router 2 router-id 1.1.1.5 area 0.0.0.2 import network 10.1.1.18 area network 172.3.3.1 area ospf enable Configure router R2. a. Configure the OSPF interface on R2.
IP routing configuration examples 143 Not So Stubby Areas (NSSA) Similar to stub areas, the not so stubby area (NSSA) can also prevent the flooding of AS-External Link State advertisements into the NSSA by replacing them with a default route. However, NSSA can also import small stub (non-OSPF) routing domains into OSPF. This allows the NSSA to import external routes, such as RIP routes, and then advertise these routes throughout the network.
IP Routing Configuration and Management 5530-24TFD(config)# interface vlan 100 5530-24TFD(config-if)# ip rip receive version rip2 send version rip2 c. Configure the OSPF interface on R1. Configure port 2/6 as a brouter port in VLAN 200. 5530-24TFD(config)# interface fast 2/6 5530-24TFD(config-if)# brouter port 2/6 vlan 200 subnet 10.1.1.18/30 d. Enable OSPF on R1. Configure R1 as an ASBR, assign OSPF Router-ID 1.1.1.5, create OSPF NSSA area 2, add the OSPF interface 10.1.1.
IP routing configuration examples 145 Configuring Area Border Routers (ABR) Configuration of an OSPF ABR is an automatic process on the Nortel Ethernet Routing Switch 5500 Series; no user intervention is required. The Nortel Ethernet Routing Switch 5500 Series automatically becomes an OSPF ABR when it has operational OSPF interfaces belonging to more than one area.
IP Routing Configuration and Management 3 Enable OSPF. Configure R1 as an ABR. Note that, by default, OSPF interface 10.1.1.22 is placed into OSPF area 0.0.0.0. Because one additional area of 0.0.0.2 is created and OSPF interface 10.1.1.17 is added to area 0.0.0.2, R1 automatically becomes an ABR. 5530-24TFD(config-router)# router-id 1.1.1.2 5530-24TFD(config-router)# area 0.0.0.2 5530-24TFD(config-router)# network 10.1.1.17 area 0.0.0.
IP routing configuration examples 147 Area ID Range Subnet/Mask Range Type Advertise Mode Metric ----------- ------------------ ------------- -------------- -----0.0.0.2 172.3.0.0/16 Summary Link Summarize 100 To display ABR status, use the show ip ospf command. Usage of this command on the example configuration would yield the following output: Router ID: 1.1.1.
IP Routing Configuration and Management ASBR distribution example Use the following procedure to replicate the ASBR distribution example: Step Action 1 Configure RIP. Configure the RIP interface on R1 by configuring port 1/31 as a brouter port in VLAN 100 and enabling RIP on this interface. 5530-24TFD(config)# interface fast 1/31 5530-24TFD(config-if)# brouter port 1/31 vlan 100 subnet 10.1.1.41/30 5530-24TFD(config)# router rip 5530-24TFD(config-router)# network 10.1.1.
IP routing configuration examples 149 5530-24TFD(config-router)# as-boundary-router enable 5530-24TFD(config-router)# router-id 1.1.1.3 5530-24TFD(config)# router ospf enable 5 Configure OSPF route distribution. Configure OSPF route distribution to import RIP into OSPF. The Nortel Ethernet Routing Switch 5500 Series distributes the RIP routes as AS-external LSA (LSA type 5), using external metric type 1.
IP Routing Configuration and Management 2 Configure a route policy. Create a route policy named Policy_Default which distributes the IP prefix list created in step 1. Note that ospf is selected as the match-protocol value. This causes the default route to be advertised through RIP only if OSPF is operational.
IP routing configuration examples 151 External route advertisement example The following procedure outlines the commands used to replicate the above configuration example: Step Action 1 Configure the RIP interface. Configure port 1/20 as a brouter port in VLAN 200 and enables RIP on this interface. 5530-24TFD(config)# interface fast 1/20 5530-24TFD(config-if)# brouter port 1/20 vlan 200 subnet 20.1.1.2/30 5530-24TFD(config)# router rip 5530-24TFD(config-router)# network 20.1.1.
IP Routing Configuration and Management Configure R1 as an ASBR, assign the OSPF Router-ID 1.1.1.5, create OSPF NSSA area 2, add the OSPF interface 10.1.1.18 to area 2, and enable OSPF on the interface. Enable ASBR and OSPF globally. 5530-24TFD(config)# router 5530-24TFD(config-router)# 5530-24TFD(config-router)# 5530-24TFD(config-router)# 5530-24TFD(config-router)# 0.0.0.2 5530-24TFD(config)# router 5 ospf router-id 1.1.1.5 as-boundary-router enable area 0.0.0.2 import nssa network 10.1.1.
IP routing configuration examples 153 Configuring a multi-area complex The multi-area complex configuration example described in this section uses five Nortel Ethernet Routing Switch 5500 Series devices (R1 to R5) in a multi-area configuration. Many of the concepts and topology descriptions that are used in this example configuration are described in the previous sections of this chapter.
IP Routing Configuration and Management • R4 is an OSPF internal router in Area 3. • R5 is an internal OSPF stub router in Area 2. • All interfaces used for this configuration are ethernet, therefore the OSPF interfaces are broadcast. • The interface priority value on R5 is set to 0, therefore R5 cannot become a designated router (DR). • Configure the OSPF Router Priority so that R1 becomes the DR (priority of 100) and R2 becomes backup designated router (BDR) with a priority value of 50.

IP routing configuration examples 189 3 Init The router received a general hello packet (without its Router ID) from another router. 4 2-Way The router received a Hello directed to it from another router. (The hello contains its Router ID) 5 ExStart Indicates the start of the Master/Slave election process. 6 Exchange Indicates the link state database (LSDB) is exchanged 7 Loading Indicates the processing state of the LSDB for input into the routing table.
IP Routing Configuration and Management A mismatch in maximum transmission unit (MTU) sizes between the routers usually causes this type of problem. For example, one router could be set for a high MTU size and the other router a smaller value. Depending on the size of the link state database, the router with the smaller value may not be able to process the larger packets and thus be stuck in this state. To avoid this problem, ensure that the MTU size value for both routers match.
IP routing configuration examples 191 00-00-5E-00-01- Where the VRID is an integer value in the range 1 to 255 that represents the virtual router identification. The virtual MAC address is assigned when VRRP is configured on a switch port or VLAN. The following example represents this process: 5530-24TFD# config terminal 5530-24TFD(config)# interface vlan 2 5530-24TFD(config-if)# ip vrrp address 199 10.1.20.
IP Routing Configuration and Management The VRRP priority setting is used to determine which router will become the VRRP master and which will become the VRRP backup. In instances where the priority setting is the same for two routers, the higher IP address becomes the tie breaker. Therefore, it is very important to set the correct VRRP priority. VRRP fast advertisement will also be enabled in this example to allow for fast failover detection.
