Views RIP view Predefined user roles network-admin Parameters route-policy route-policy-name: Specifies a routing policy by its name, a case-sensitive string of 1 to 63 characters.
Views User view Predefined user roles network-admin Parameters process-id: Specifies a RIP process by its ID in the range of 1 to 65535. Usage guidelines After executing the command, you are prompted to confirm the operation. Examples # Reset RIP process 100. reset rip 100 process Reset RIP process? [Y/N]:y reset rip statistics Use reset rip statistics to clear statistics for a RIP process.
Views System view Predefined user roles network-admin Parameters process-id: Specifies a RIP process by its ID in the range of 1 to 65535. The default is 1. Usage guidelines You must enable a RIP process before configuring global parameters for it. This restriction does not apply to configuring interface parameters. If you disable a RIP process, the configured interface parameters become invalid. Examples # Enable RIP process 1 and enter RIP view.
rfc2453: Uses the message format defined in RFC 2453 (IETF standard). simple: Specifies the simple authentication mode. Usage guidelines A newly configured key overwrites the old one, if any. Although you can specify an authentication mode for RIPv1 in interface view, the configuration does not take effect because RIPv1 does not support authentication. For security purposes, all keys, including keys configured in plain text, are saved in cipher text.

Views Interface view Predefined user roles network-admin Parameters only: Advertises only a default route. originate: Advertises both a default route and other routes. cost: Specifies a cost for the default route, in the range of 1 to 15. The default is 1. no-originate: Advertises only non-default routes.
Predefined user roles network-admin Parameters process-id: Specifies a RIP process by its ID in the range of 1 to 65535. exclude-subip: Excludes secondary IP addresses from being enabled with RIP. Without this keyword, RIP is also enabled on secondary IP addresses of a RIP-enabled interface. Usage guidelines The rip enable command has a higher priority than the network command. Examples # Enable RIP process 100 on VLAN-interface 10.
Syntax rip max-packet-length value undo rip max-packet-length Default The maximum length of RIP packets is 512 bytes. Views Interface view Predefined user roles network-admin Parameters value: Sets the maximum length of RIP packets, in the range of 32 to 65535 bytes. Usage guidelines If the configured value in the rip max-packet-length command is greater than the MTU of an interface, the interface MTU value is used as the maximum length of RIP packets.
Predefined user roles network-admin Parameters route-policy route-policy-name: Uses the specified routing policy to add an additional metric for the routes matching it. The route-policy-name argument is a case-sensitive string of 1 to 63 characters. value: Adds an additional metric to inbound routes, in the range of 0 to 16. Usage guidelines When a valid RIP route is received, the system adds a metric to it and then installs it into the routing table.
Views Interface view Predefined user roles network-admin Parameters route-policy route-policy-name: Uses the specified routing policy to add an additional metric for the routes matching it. The route-policy-name argument is a case-sensitive string of 1 to 63 characters. value: Adds an additional metric to outbound routes, in the range of 1 to 16. Usage guidelines With the command configured on an interface, the metric of RIP routes sent on the interface will be increased.
Views System view Predefined user roles network-admin Parameters process-id: Specifies a RIP process by its ID in the range of 1 to 65535. Usage guidelines If the specified process ID does not exist, the MIB binding configuration fails. Deleting a RIP process bound to MIB operation deletes the MIB binding configuration. After the RIP process is deleted, MIB operation is bound to the RIP process with the smallest process ID. Examples # Bind MIB operation to RIP process 100.
Syntax rip poison-reverse undo rip poison-reverse Default The poison reverse function is disabled. Views Interface view Predefined user roles network-admin Examples # Enable the poison reverse function on VLAN-interface 10. system-view [Sysname] interface vlan-interface 10 [Sysname-Vlan-interface10] rip poison-reverse rip split-horizon Use rip split-horizon to enable the split horizon function. Use undo rip split-horizon to disable the split horizon function.
rip summary-address Use rip summary-address to configure RIPv2 to advertise a summary route on an interface. Use undo rip summary-address to remove the configuration. Syntax rip summary-address ip-address { mask-length | mask } undo rip summary-address ip-address { mask-length | mask } Default RIPv2 does not advertise a summary route. Views Interface view Predefined user roles network-admin Parameters ip-address: Specifies the destination IP address of the summary route.
Views Interface view Predefined user roles network-admin Parameters 1: Specifies the RIP version as RIPv1. 2: Specifies the RIP version as RIPv2. [ broadcast | multicast ]: Sends RIPv2 messages in broadcast mode or multicast mode (default). Usage guidelines If an interface has no RIP version configured, it uses the global RIP version. Otherwise, it uses the RIP version configured on it. An interface running RIPv1 can perform the following operations: • Sends RIPv1 broadcast messages.
Views RIP view Predefined user roles network-admin Parameters interface-type interface-number: Disables a specified interface from sending RIP messages. all: Disables all interfaces from sending RIP messages. Examples # Configure all VLAN interfaces to operate in silent mode except VLAN-interface 10. system-view [Sysname] rip 100 [Sysname-rip-100] silent-interface all [Sysname-rip-100] undo silent-interface vlan-interface 10 [Sysname-rip-100] network 131.108.0.
timers Use timers to configure RIP timers. Use undo timers to restore the default. Syntax timers { garbage-collect garbage-collect-value | suppress suppress-value | timeout timeout-value | update update-value } * undo timers { garbage-collect | suppress | timeout | update } * Default The garbage-collect timer is 120 seconds, the suppress timer is 120 seconds, the timeout timer is 180 seconds, and the update timer is 30 seconds.
[Sysname-rip-100] timers update 5 timeout 15 suppress 15 garbage-collect 30 validate-source-address Use validate-source-address to enable source IP address check on inbound RIP routing updates. Use undo validate-source-address to disable source IP address check. Syntax validate-source-address undo validate-source-address Default Source IP address check on inbound RIP routing updates is enabled.
Usage guidelines An interface prefers the RIP version configured on it over the global RIP version. If no RIP version is specified for the interface and the global version is RIPv1, the interface uses RIPv1, and it can send RIPv1 broadcasts, and receive RIPv1 broadcasts and unicasts. If no RIP version is specified for the interface and the global version is RIPv2, the interface uses RIPv2 multicast mode, and it can send RIPv2 multicasts, and receive RIPv2 broadcasts, multicasts, and unicasts.

Usage guidelines You can enable multiple OSPF processes on a router and specify different router IDs for them. Enable an OSPF process before performing other tasks. Examples # Enable OSPF process 100 and specify router ID 10.10.10.1. system-view [Sysname] ospf 100 router-id 10.10.10.1 [Sysname-ospf-100] ospf area Use ospf area to enable OSPF on an interface. Use undo ospf area to remove the configuration.
ospf authentication-mode Use ospf authentication-mode to set the authentication mode and key on an interface. Use undo ospf authentication-mode to remove specified configuration.
During key rollover, OSPF sends multiple packets that contain both the new and old MD5/HMAC-MD5 authentication keys to make sure all neighbor devices can pass the authentication. 2. Configure the new MD5/HMAC-MD5 authentication key on all neighbor devices. When the local device receives packets with the new key from all neighbor devices, it exits MD5 key rollover. 3. Delete the old MD5/HMAC-MD5 authentication key from the local device and all its neighbors.
Views Interface view Predefined user roles network-admin Parameters echo: Enables BFD single-hop echo detection. Without this keyword, this command enables BFD bidirectional control detection.

Use undo ospf dr-priority to restore the default value. Syntax ospf dr-priority priority undo ospf dr-priority Default The router priority is 1.
Views Interface view Predefined user roles network-admin Usage guidelines If you enable LFA on an interface, it can be selected as a backup interface. After you disable LFA on the interface, it cannot be selected as a backup. Examples # Disable VLAN-interface 11 from calculating a backup next hop by using the LFA algorithm.
ospf mtu-enable Use ospf mtu-enable to enable an interface to add the interface MTU into DD packets. Use undo ospf mtu-enable to restore the default. Syntax ospf mtu-enable undo ospf mtu-enable Default The MTU in DD packets is 0. Views Interface view Predefined user roles network-admin Usage guidelines After a virtual link is established through a Virtual-Template or Tunnel, two devices on the link from different vendors might have different MTU values.
Predefined user roles network-admin Parameters broadcast: Specifies the network type as broadcast. nbma: Specifies the network type as NBMA. p2mp: Specifies the network type as P2MP. unicast: Specifies the P2MP interface to unicast OSPF packets. By default, a P2MP interface multicasts OSPF packets. p2p: Specifies the network type as P2P. Usage guidelines If a router on a broadcast network does not support multicast, configure the network type for the connected interfaces as NBMA.
Views Interface view Predefined user roles network-admin Parameters disable: Disables prefix suppression on an interface. Usage guidelines To disable prefix suppression on an interface associated with an OSPF process that has been enabled with prefix suppression, execute the ospf prefix-suppression disable command on that interface. For more information, see "prefix-suppression." Examples # Enable prefix suppression on VLAN-interface 10.
Examples # Configure the dead interval for VLAN-interface 10 as 60 seconds. system-view [Sysname] interface vlan-interface 10 [Sysname-Vlan-interface10] ospf timer dead 60 Related commands ospf timer hello ospf timer hello Use ospf timer hello to set the hello interval on an interface. Use undo ospf timer hello to restore the default.
Syntax ospf timer poll seconds undo ospf timer poll Default The poll interval is 120 seconds on an interface. Views Interface view Predefined user roles network-admin Parameters seconds: Specifies the poll interval in the range of 1 to 2147483647 seconds. Usage guidelines When an NBMA interface finds its neighbor is down, it sends hello packets at the poll interval. The poll interval must be at least four times the hello interval.
Usage guidelines After sending an LSA, an interface waits for an acknowledgement packet. If the interface receives no acknowledgement within the retransmission interval, it retransmits the LSA. To avoid unnecessary retransmissions, set an appropriate retransmission interval. For example, you can set a large retransmission interval value on a low-speed link. Examples # Set the LSA retransmission interval to 8 seconds on VLAN-interface 10.

{ If RFC 2328 is not compatible with RFC 1583, the intra-area route in a non-backbone area is preferred to reduce the burden of the backbone area. The inter-area route and intra-area route in the backbone area have equal preference. 2. Selects the route with lower cost if two routes have equal preference. 3. Selects the route with larger originating area ID if two routes have equal cost. To avoid routing loops, HP recommends setting identical RFC 1583-compatibility on all routers in a routing domain.
Examples # Configure a global router ID as 1.1.1.1. system-view [Sysname] router id 1.1.1.1 silent-interface (OSPF view) Use silent-interface to disable an interface or all interfaces from receiving and sending OSPF packets. Use undo silent-interface to remove the configuration. Syntax silent-interface { interface-type interface-number | all } undo silent-interface { interface-type interface-number | all } Default An interface can receive and send OSPF packets.

Parameters maximum-interval: Specifies the maximum OSPF SPF calculation interval in the range of 1 to 60 seconds. minimum-interval: Specifies the minimum OSPF SPF calculation interval in the range of 10 to 60000 milliseconds. incremental-interval: Specifies the incremental OSPF SPF calculation interval in the range of 10 to 60000 milliseconds. Usage guidelines Based on the LSDB, an OSPF router uses SPF to calculate a shortest path tree with itself as the root.
no-summary: Used only on a stub ABR. With this keyword, the ABR advertises only a default route in a Type-3 LSA into the stub area without advertising any other Type-3 LSAs (such a stub area is a totally stub area). Usage guidelines To remove the default-route-advertise-always or stub no-summary configuration on the ABR, execute the stub command again to overwrite it. To configure an area as a stub area, issue the stub command on all routers attached to the area.
Usage guidelines The router LSAs sent by the stub router over different links contain different link type values. A value of 3 represents a link to a stub network, and the cost of the link is not changed. A value of 1, 2, or 4 represents a point-to-point link, a link to a transit network, or a virtual link, and the cost of such links is set to 65535. Neighbors on such links will not send packets to the stub router as long as they have a route with a smaller cost. Examples # Configure a stub router.
vlink-peer (OSPF area view) Use vlink-peer to configure a virtual link. Use undo vlink-peer to remove a virtual link. Syntax vlink-peer router-id [ dead seconds | hello seconds | { { hmac-md5 | md5 } key-id { cipher cipher-string | plain plain-string } | simple { cipher cipher-string | plain plain-string } } | retransmit seconds | trans-delay seconds ] * undo vlink-peer router-id [ dead | hello | { hmac-md5 | md5 } key-id | retransmit | simple | trans-delay ] * Default No virtual link is configured.
• The smaller the hello interval is, the faster the network converges, and the more network resources are consumed. • A retransmission interval that is too small can cause unnecessary retransmissions. A large value is appropriate for a low speed link. • Specify an appropriate transmission delay with the trans-delay keyword. For security purposes, all keys, including keys configured in plain text, are saved in cipher text.
IS-IS commands area-authentication-mode Use area-authentication-mode to specify an area authentication mode and a password. Use undo area-authentication-mode to restore the default. Syntax area-authentication-mode { md5 | simple } { cipher cipher-string | plain plain-string } [ ip | osi ] undo area-authentication-mode Default No area authentication or password is configured. Views IS-IS view Predefined user roles network-admin Parameters md5: Specifies the MD5 authentication mode.

Predefined user roles network-admin Usage guidelines Suppressing the SA bit is mainly for avoiding black hole route. If a router starts or reboots without keeping the local forwarding table, sending packets to the router might result in a severe packet loss. To avoid this, you can set the SA bit of the hello packet sent by the GR restarter to 1. Upon receiving such hello packets, the GR helpers will not advertise the GR restarter through LSP. Examples # Suppress the SA bit during graceful restart.

ebgp-interface-sensitive Use ebgp-interface-sensitive to enable quick reestablishment of direct EBGP sessions. Use undo ebgp-interface-sensitive to disable the function. Syntax ebgp-interface-sensitive undo ebgp-interface-sensitive Default Quick reestablishment of direct EBGP sessions is enabled. Views BGP view Predefined user roles network-admin Usage guidelines This command enables BGP to quickly handle direct EBGP link failures.
Parameters route-policy-name: Specifies a routing policy by its name, a case-sensitive string of 1 to 63 characters. Usage guidelines There are two methods to configure BGP FRR: • Method 1—Execute the pic command in BGP address family view. BGP calculates a backup next hop for a BGP route in the address family if there are two or more unequal-cost routes to reach the destination.
prefix-list prefix-list-name: Specifies an IPv4 prefix list by its name, a case-sensitive string of 1 to 63 characters, to match routes by destination. protocol: Filters routes redistributed from the routing protocol that can be direct, isis, ospf, rip, or static. process-id: Specifies a routing protocol by its ID in the range of 1 to 65535. This argument is available only when the protocol is isis, ospf, or rip.
Default Received BGP routes are not filtered. Views BGP IPv4 unicast address family view Predefined user roles network-admin Parameters acl-number: Specifies an ACL by its number in the range of 2000 to 3999 to match routes by destination. prefix-list prefix-list-name: Specifies an IPv4 prefix list by its name, a case-sensitive string of 1 to 63 characters, to match routes by destination.
• peer filter-policy • peer prefix-list • peer route-policy graceful-restart Use graceful-restart to enable BGP Graceful Restart capability. Use undo graceful-restart to disable BGP Graceful Restart capability. Syntax graceful-restart undo graceful-restart Default BGP Graceful Restart capability is disabled. Views BGP view Predefined user roles network-admin Usage guidelines Graceful Restart (GR) ensures continuous forwarding when BGP restarts or an active/standby switchover occurs.
Default The GR timer is 150 seconds. Views BGP view Predefined user roles network-admin Parameters timer: Specifies the GR timer in the range of 3 to 600 seconds. Usage guidelines The GR restarter sends the GR timer to the GR helper in an Open message. When the GR helper detects that an active/standby switchover or a BGP restart occurs on the GR restarter, the GR helper marks all routes learned from the GR restarter as stale and starts the GR timer.
Parameters timer: Specifies the time to wait for the End-of-RIB marker, in the range of 3 to 300 seconds. Usage guidelines BGP uses this timer to control the time to receive updates from the peer. The timer is not advertised to the peer. After the GR restarter and GR helper reestablish a BGP session, they start this timer.
Usage guidelines In a large-scale network, many peers can use the same route selection policy. You can configure a peer group and add these peers into this group. In this way, peers can share the same policy as the peer group. When the policy of the group is modified, the modification also applies to peers in it. If the internal or external keyword is not specified, the command creates an IBGP peer group.
import-route Use import-route to enable BGP to redistribute routes from an IGP protocol. Use undo import-route to disable route redistribution from an IGP protocol. Syntax import-route protocol [ { process-id | all-processes } [ med med-value | route-policy route-policy-name ] *] undo import-route protocol [ process-id | all-processes ] Default BGP does not redistribute IGP routes.
log-peer-change Use log-peer-change to enable the logging of BGP session state changes. Use undo log-peer-change to disable the function. Syntax log-peer-change undo log-peer-change Default Logging of BGP session state changes is enabled. Views BGP view Predefined user roles network-admin Usage guidelines After you execute the log-peer-change command, BGP logs session establishment and disconnection events. To view the log information, use the display bgp peer ipv4 unicast log-info command.
Views BGP IPv4 unicast address family view Predefined user roles network-admin Parameters ip-address: Specifies an IPv4 network address. If the mask or mask-length is not specified, natural mask is used. mask: Specifies a mask in dotted decimal notation. mask-length: Specifies a mask length in the range of 0 to 32. route-policy route-policy-name: Specifies a routing policy by its name, a case-sensitive string of 1 to 63 characters, to filter routes or set the route attributes.
mask: Specifies a mask of the network address in dotted decimal notation. mask-length: Specifies a mask length in the range of 0 to 32. Usage guidelines Different routing protocols might find different routes to the same destination. However, not all of those routes are optimal. For route selection, routing protocols, direct routes, and static routes are assigned different preferences. The route with the highest preference is preferred.
Usage guidelines The COMMUNITY attribute is a group of specific data carried in update messages. A route can carry one or more COMMUNITY attribute values (each is represented by a 4-byte integer). The receiving router processes the route (for example, determining whether to advertise the route and the scope for advertising the route) based on the COMMUNITY attribute values. After you execute the peer advertise-community command, routing updates advertised to the peer carry the COMMUNITY attribute.
Usage guidelines To meet increasing user demands, BGP defines a new attribute—extended community attribute. The extended community attribute has the following advantages over the COMMUNITY attribute: • The extended community attribute has an 8-byte length. • The extended community attribute supports various types. You can select an extended community attribute type as needed to implement route filtering and control. This simplifies configuration and management.
number: Specifies the number of times for which the local AS number can appear, in the range of 1 to 10. The default number is 1. If the number of times for which the local AS number appears in a route is more than the specified number, BGP considers that a routing loop occurs and discards the route. Usage guidelines By default, BGP does not receive routes that contain the local AS number in the AS_PATH attribute to avoid routing loops.
Examples # Create BGP peer 1.1.1.1 and specify its AS number as 100. system-view [Sysname] bgp 100 [Sysname-bgp] peer 1.1.1.1 as-number 100 Related commands • display bgp peer ipv4 unicast • peer enable • peer group peer as-number (for a BGP peer group) Use peer as-number to specify an AS number for a peer group.

If the interface IP address that is selected as the router ID is removed or modified, a new router ID is selected. Other events, (the interface goes down; after a physical interface address is selected as the router ID, an IP address is configured for a loopback interface; a higher interface IP address is configured) will not trigger a router ID re-selection. After a router ID is changed, use the reset command to make it effective. Examples # Configure a global router ID as 1.1.1.1.
Related commands router id (system view) snmp-agent trap enable bgp Use snmp-agent trap enable bgp to enable SNMP notifications for BGP. Use undo snmp-agent trap enable bgp to disable SNMP notifications for BGP. Syntax snmp-agent trap enable bgp undo snmp-agent trap enable bgp Default SNMP notifications for BGP are enabled.
Predefined user roles network-admin Usage guidelines After the summary automatic command is configured, BGP summarizes IGP subnets redistributed by the import-route command. Automatic summary routes can be manually summarized, but cannot be added to the IP routing table. Examples # Configure automatic route summarization for redistributed IGP subnet routes.
If the holdtime settings on the local and peer routers are different, the smaller one is used. If the holdtime is configured as 0, no keepalive message will be sent to the peer, and the peer session will never time out. If the keepalive interval is configured as 0 and the negotiated holdtime is not 0, one third of the holdtime is taken as the interval for sending keepalive messages.
Policy-based routing commands apply next-hop Use apply next-hop to set a next hop. Use undo apply next-hop to remove the configuration.
