Usage guidelines BFD echo-mode detection only works for a RIP neighbor one hop away. Using the undo peer command does not delete the neighbor relationship at once and cannot bring down the BFD session at once. The rip bfd enable command and the rip bfd enable destination command are mutually exclusive and cannot be configured on a device at the same time. Examples # Enable BFD on RIP interface Ethernet 1/1.
rip default-route Use rip default-route to configure the RIP interface to advertise a default route with the specified metric. Use undo rip default-route to disable the RIP interface from sending a default route. Syntax rip default-route { { only | originate } [ cost cost ] | no-originate } undo rip default-route Default A RIP interface can advertise a default route if the RIP process is configured with default route advertisement.

Examples # Configure Ethernet 1/1 to add a metric of 6 for the inbound route 1.0.0.0/8 and to add a metric of 2 for other inbound routes. system-view [Sysname] ip ip-prefix 123 permit 1.0.0.0 8 [Sysname] route-policy abc permit node 0 [Sysname-route-policy] if-match ip-prefix 123 [Sysname-route-policy] apply cost 6 [Sysname] interface ethernet 1/1 [Sysname-Ethernet1/1] rip metricin route-policy abc 2 rip metricout Use rip metricout to configure an interface to add a metric to outbound routes.
[Sysname-route-policy] if-match ip-prefix 123 [Sysname-route-policy] apply cost 6 [Sysname] interface ethernet 1/1 [Sysname-Ethernet1/1] rip metricout route-policy abc 2 rip mib-binding Use rip mib-binding to bind MIB operations with a specified RIP process, so that the RIP process can receive SNMP requests. Use undo rip mib-binding to restore the default. Syntax rip mib-binding process-id undo rip mib-binding Default MIB operations are bound to RIP process 1.
Default command level 2: System level Examples # Enable Ethernet 1/1 to receive RIP messages. system-view [Sysname] interface ethernet1/1 [Sysname-Ethernet1/1] rip output rip poison-reverse Use rip poison-reverse to enable the poison reverse function. Use undo rip poison-reverse to disable the poison reverse function. Syntax rip poison-reverse undo rip poison-reverse Default The poison reverse function is disabled.
Usage guidelines • The split horizon function is necessary for preventing routing loops. To disable it in special cases, make sure it is necessary. • In Frame Relay, X.25 and other non-broadcast multi-access (NBMA) networks, split horizon should be disabled if multiple VCs are configured on the primary and secondary interfaces to ensure route advertisement. For detailed information, see Layer 2—WAN Configuration Guide.

An intra-area route is a route in an OSPF area. An inter-area route is between any two OSPF areas. Both of them are internal routes. An external route is a route to a destination outside the OSPF AS. A Type-1 external route has high reliability. Its cost is comparable with the cost of OSPF internal routes. The cost from an OSPF router to a Type-1 external route's destination equals the cost from the router to the ASBR plus the cost from the ASBR to the external route's destination.
Usage guidelines When a network topology is changed, ISPF recomputes only the affected part of the shortest path tree (SPT), instead of the entire SPT. Examples # Enable OSPF ISPF. system-view [Sysname] ospf 100 [Sysname-ospf-100] ispf enable log-peer-change Use log-peer-change to enable the logging of OSPF neighbor state changes. Use undo log-peer-change to disable the logging. Syntax log-peer-change undo log-peer-change Default The logging is enabled.
Views OSPF view Default command level 2: System level Parameters interval: Specifies the LSA arrival interval in milliseconds, in the range of 0 to 60000. Usage guidelines If an LSA that has the same LSA type, LS ID, originating router ID with the previous LSA is received within the interval, the LSA is discarded. This feature helps protect routers and bandwidth from being over-consumed due to frequent network changes.
incremental-interval: Specifies the LSA generation incremental interval in milliseconds, in the range of 10 to 60000. The default is 5000. Usage guidelines When network changes are not frequent, LSAs are generated at the minimum-interval. If network changes become frequent, the LSA generation interval is incremented by incremental-interval × 2n-2 (n is the number of generation times) each time a LSA generation occurs until the maximum-interval is reached.

Using this command can make them compatible.
If no global router ID is configured, the highest loopback interface IP address, if any, is used as the router ID. If no loopback interface IP address is available, the highest physical interface IP address is used, regardless of the interface status. During an active/standby switchover, the standby main board checks whether the previous router ID that is backed up before switchover is valid. If not, it selects a new router ID.

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.
Examples # Configure all the interfaces running OSPF process 1 to send up to 10 LSU packets every 30 milliseconds. system-view [Sysname] ospf 1 [Sysname-ospf-1] transmit-pacing interval 30 count 10 vlink-peer (OSPF area view) Use vlink-peer to configure a virtual link. Use undo vlink-peer to remove a virtual link.
Usage guidelines As defined in RFC 2328, all non-backbone areas must maintain connectivity to the backbone. You can use the vlink-peer command to configure a virtual link to connect an area to the backbone. Considerations on parameters: • The smaller the hello interval is, the faster the network converges and the more network resources are consumed. • A so small retransmission interval will lead to unnecessary retransmissions. A big value is appropriate for a low speed link.

Use undo graceful-restart interval to restore the default Graceful Restart interval.
Views IS-IS view Default command level 2: System level 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 do not advertise the GR restarter through LSP.
• For the styles of wide, wide-compatible, the cost is in the range of 0 to 16777215. cost-type { external | internal }: Specifies the cost type. The internal type indicates internal routes, and the external type indicates external routes. If external is specified, the cost of a redistributed route to be advertised is added by 64 to make internal routes take priority over external routes. The type is external by default.
Default No route leaking is configured. Views IS-IS view Default command level 2: System level Parameters acl-number: Specifies an ACL by its number in the range of 2000 to 3999 to filter routes from Level-2 to Level-1.

Use undo isis authentication-mode to restore the default.
If neither ip nor osi is specified, the OSI related fields in LSPs are checked. The level-1 and level-2 keywords are configurable on an interface that has had IS-IS enabled with the isis enable command. Examples # On Ethernet 1/1, configure the Level-1 adjacency authentication mode as simple, and set the plaintext password to 123456.
Default An interface can establish either the Level-1 or Level-2 adjacency. Views Interface view Default command level 2: System level Parameters level-1: Sets the circuit level to Level-1. level-1-2: Sets the circuit level to Level-1-2. level-2: Sets the circuit level to Level-2. Usage guidelines For a Level-1 (Level-2) router, the circuit level can only be Level-1 (Level-2).
Usage guidelines Interfaces with different network types operate differently. For example, broadcast interfaces on a network need to elect a DIS and flood CSNP packets to synchronize the LSDBs, and P2P interfaces on a network need not elect a DIS and have a different LSDB synchronization mechanism. If only two routers exist on a broadcast network, configure the network type of attached interfaces as P2P to avoid DIS election and CSNP flooding, saving network bandwidth, and speeding up network convergence.
Examples # Configure the Level-2 IS-IS cost as 5 for Serial 2/0. system-view [Sysname] interface serial 2/0 [Sysname-Serial2/0] isis cost 5 level-2 Relate commands circuit-cost isis dis-name NOTE: • This command is not supported on a point-to-point interface. • This command is not available in loopback interface view.

Use undo isis mib-binding to restore the default. Syntax isis mib-binding process-id undo isis mib-binding Default MIBs are bound with IS-IS process 1.
Default command level 2: System level Usage guidelines An IS-IS PPP interface requires the sender of a hello packet must be on the same network segment as it. Otherwise, it discards the hello packet. You can use the isis peer-ip-ignore command to disable this restriction. Examples # Configure Serial2/0 not to check the peer's IP address in the received Hello packets.
Syntax isis small-hello undo isis small-hello Default An interface sends standard hello packets. Views Interface view Default command level 2: System level Examples # Configure the Serial 2/0 interface to send small Hello packets. system-view [Sysname] interface serial 2/0 [Sysname-Serial2/0] isis small-hello isis timer csnp NOTE: This command is not supported in loopback interface view. Use isis timer csnp to specify on the DIS of a broadcast network the interval for sending CSNP packets.
Examples # Configure Level-2 CSNP packets to be sent every 15 seconds over Serial 2/0. system-view [Sysname] interface serial 2/0 [Sysname-Serial2/0] isis timer csnp 15 level-2 isis timer hello NOTE: This command is not supported in loopback interface view. Use isis timer hello to specify the interval for sending hello packets. Use undo isis timer hello to restore the default.
Related commands isis timer holding-multiplier isis timer holding-multiplier NOTE: This command is not available in loopback interface view. Use isis timer holding-multiplier to specify the IS-IS hello multiplier. Use undo isis timer holding-multiplier to restore the default. Syntax isis timer holding-multiplier value [ level-1 | level-2 ] undo isis timer holding-multiplier [ value ] [ level-1 | level-2 ] Default The default IS-IS hello multiplier is 3.
isis timer lsp NOTE: This command is not available in loopback interface view. Use isis timer lsp to configure the minimum interval for sending LSPs on the interface and specify the maximum LSPs that can be sent per time. Use undo isis timer lsp to restore the default of 33 milliseconds. Syntax isis timer lsp time [ count count ] undo isis timer lsp Default The minimum interval for sending LSPs on the interface is 33 milliseconds.
Default The retransmission interval is 5 seconds. Views Interface view Default command level 2: System level Parameters seconds: Specifies the interval in seconds for retransmitting LSP packets, in the range of 1 to 300. Usage guidelines A P2P link requires a response to a sent LSP. If no response is received within the retransmission interval, the LSP is retransmitted. You do not need to use this command over a broadcast link where CSNPs are broadcast periodically.
level-1-2: Configures the router to work on Level-1-2, which means it calculates routes and maintains the LSDBs for both L1 and L2. level-2: Configures the router to work on Level-2, which means it calculates routes and maintains the LSDB for L2 only. Usage guidelines Configure all the routers as either Level-1 or Level-2 if only one area is present, because the routers do not need to maintain two identical databases at the same time.
Syntax is-name map sys-id map-sys-name undo is-name map sys-id Views IS-IS view Default command level 2: System level Parameters sys-id: System ID or pseudonode ID of a remote IS. map-sys-name: Specifies a host name for the remote IS, a string of 1 to 64 characters. Usage guidelines Each remote IS system ID corresponds to only one name. Examples # Map the host name RUTB to the system ID 0000.0000.0041 of the remote IS. system-view [Sysname] isis 1 [Sysname-isis-1] is-name map 0000.0000.
Use undo log-peer-change to disable the logging. Syntax log-peer-change undo log-peer-change Default The logging is enabled.

undo preference Default IS-IS preference is 15. Views IS-IS view Default command level 2: System level Parameters preference: Specifies the preference for IS-IS protocol, in the range of 1 to 255. route-policy route-policy-name: Routing policy name, a case-sensitive string of 1 to 63 characters. The preference applies to routes passing the routing policy. Usage guidelines If a routing policy is specified in this command, the preference (if any) set by the routing policy applies to those matched routes.
Usage guidelines If no IS-IS route is assigned a high priority, IS-IS host routes are processed first in network convergence because they have higher priority than other types of IS-IS routes. Examples # Assign a high priority to the IS-IS routes matching IP prefix list standtest. system-view [Sysname] isis 1 [Sysname-isis-1] priority high ip-prefix standtest reset isis all Use reset isis all to clear all IS-IS data structure information.

Views BGP view, BGP-VPN instance view Default command level 2: System level Usage guidelines If several paths to one destination are available, the path with the smallest MED is selected. Do not use this command unless associated ASs adopt the same IGP protocol and routing selection method.
Parameters as-number: Specifies the number of the AS that contains multiple sub-ASs, in the range of 1 to 4294967295. Usage guidelines Configuring a confederation can reduce IBGP connections in a large AS. You can split the AS into several sub-ASs, and each sub-AS remains fully meshed. These sub-ASs form a confederation. Key IGP attributes of a route, such as the next hop, MED, or local preference, are not discarded when crossing each sub-AS.
Usage guidelines All devices should be configured with this command to interact with those nonstandard devices in the confederation. Examples # AS 100 contains routers not compliant with RFC 3065 and includes two sub-ASs, 64000 and 65000.

Syntax maximum load-balancing maximum undo maximum load-balancing Views OSPFv3 view Default command level 2: System level Parameters maximum: Specifies the maximum number of ECMP routes. Examples # Configure the maximum number of ECMP routes as 6. system-view [Sysname] ospfv3 1 [Sysname-ospfv3-1] maximum load-balancing 6 ospfv3 Use ospfv3 to enable an OSPFv3 process and enter OSPFv3 view. Use undo ospfv3 to disable an OSPFv3 process.
[Sysname] ospfv3 120 [Sysname-ospfv3-120] router-id 1.1.1.1 Related commands router-id ospfv3 area Use ospfv3 area to enable an OSPFv3 process on the interface and specify the area for the interface. Use undo ospfv3 area to disable an OSPFv3 process. Syntax ospfv3 process-id area area-id [ instance instance-id ] undo ospfv3 process-id area area-id [ instance instance-id ] Default OSPFv3 is not enabled on an interface.
Views Interface view Default command level 2: System level Parameters instance-id: Specifies an instance by its ID in the range of 0 to 255. The default is 0. Examples # Enable BFD on Ethernet 1/1 in instance 1. system-view [Sysname] interface ethernet 1/1 [Sysname-Ethernet1/1] ospfv3 bfd enable instance 1 ospfv3 cost Use ospfv3 cost to configure the OSPFv3 cost of the interface in an instance. Use undo ospfv3 cost to restore the default OSPFv3 cost of the interface in an instance.
ospfv3 dr-priority Use ospfv3 dr-priority to set the DR priority for an interface in an instance. Use undo ospfv3 dr-priority to restore the default value. Syntax ospfv3 dr-priority priority [ instance instance-id ] undo ospfv3 dr-priority [ priority ] [ instance instance-id ] Default The DR priority on an interface is 1. Views Interface view Default command level 2: System level Parameters priority: Specifies a DR priority in the range of 0 to 255.
Parameters policy-name: Specifies an IPsec policy by its name, a string of 1 to 15 characters. instance-id: Specifies an instance by its ID in the range of 0 to 255. The default is 0. Usage guidelines The IPsec policy to be applied must have been configured. Examples # Apply IPsec policy policy001 to OSPFv3 interface Serial 2/0.
Default The network type of an interface depends on its link layer protocol. For example: • For PPP, the default network type is P2P. • For Ethernet, the default network type is broadcast. Views Interface view Default Command level 2: System level Parameters broadcast: Specifies the network type as Broadcast. nbma: Specifies the network type as NBMA. p2mp: Specifies the network type as P2MP. p2p: Specifies the network type as P2P. non-broadcast: Specifies the interface to send packets in unicast mode.
Usage guidelines A router uses the priority set with the ospfv3 peer command to determine whether to send a hello packet to the neighbor rather than use it for DR election. Examples # Specify the neighbor fe80::1111. system-view [Sysname] interface ethernet 1/1 [Sysname-Ethernet1/1] ospfv3 peer fe80::1111 ospfv3 timer dead Use ospfv3 timer dead to configure the OSPFv3 neighbor dead time for an interface that belongs to a specified instance. Use undo ospfv3 timer dead to restore the default.
ospfv3 timer hello Use ospfv3 timer hello to configure the hello interval for an interface that belongs to an instance. Use undo ospfv3 timer hello to restore the default. Syntax ospfv3 timer hello seconds [ instance instance-id ] undo ospfv3 timer hello [ seconds ] [ instance instance-id ] Default The hello interval is 10 seconds for P2P and Broadcast interfaces and is not supported on the P2MP or NBMA interfaces.
Parameters interval: Specifies the LSA retransmission interval in the range of 1 to 65535 seconds. instance-id: Specifies an instance by its ID in the range of 0 to 255. The default is 0. Usage guidelines After sending a LSA to its neighbor, the device waits for an acknowledgement. If receiving no acknowledgement after the LSA retransmission interval elapses, it retransmits the LSA. The LSA retransmission interval should not be too small for avoidance of unnecessary retransmissions.
Syntax ospfv3 trans-delay seconds [ instance instance-id ] undo ospfv3 trans-delay [ seconds ] [ instance instance-id ] Default The transmission delay is 1s. Views Interface view Default command level 2: System level Parameters seconds: Specifies the transmission delay in the range of 1 to 3600 seconds. instance-id: Specifies an instance by its ID in the range of 0 to 255.

Usage guidelines The smaller the value is, the higher the preference is. A router might run multiple routing protocols. Each protocol has a preference.
silent-interface(OSPFv3 view) Use silent-interface to disable the specified interface from receiving and sending OSPFv3 packets. Use undo silent-interface to restore the default. Syntax silent-interface { interface-type interface-number | all } undo silent-interface { interface-type interface-number | all } Default An interface is able to receive and send OSPFv3 packets.
Views OSPFv3 view Default command level 2: System level Parameters delay-interval: Specifies the interval in seconds between when OSPFv3 receives a topology change and when it starts SPF calculation. The value range is 0 to 65535. hold-interval: Specifies the hold interval in seconds between two consecutive SPF calculations, in the range of 0 to 65535.
Usage guidelines When an area is configured as a stub area, all the routers attached to the area must be configured with the stub command. Examples # Configure OSPFv3 area 1 as a stub area. system-view [Sysname] ospfv3 1 [Sysname-ospfv3-1] area 1 [Sysname-ospfv3-1-area-0.0.0.1] stub Related commands default-cost vlink-peer (OSPFv3 area view) Use vlink-peer to create and configure a virtual link. Use undo vlink-peer to remove a virtual link.
can be considered as an interface with OSPFv3 enabled, because parameters such as hello, dead, retransmit and trans-delay are configured in the similar way. Both ends of a virtual link are ABRs that are configured with the vlink-peer command. If you have enabled the GR capability for the current process, you cannot execute the vlink-peer command for the process. Examples # Create a virtual link to 10.110.0.3. system-view [Sysname] ospfv3 1 [Sysname-ospfv3-1] area 10.0.0.

Syntax router-id router-id undo router-id Views BGP view Default command level 2: System level Parameters router-id: Specifies a router ID in IP address format. Usage guidelines To run IPv6 BGP protocol, a router must have a router ID, an unsigned 32-bit integer and the unique ID of the router in the AS. Specify a router ID manually, or the system selects the highest IPv4 address among loopback interface addresses as the router ID.
Parameters None Usage guidelines With this feature enabled and when a non-BGP router is responsible for forwarding packets in an AS, IPv6 BGP speakers in the AS cannot advertise routing information to other ASs unless all routers in the AS know the latest routing information. Examples # Enable the route synchronization between IPv6 BGP and IGP.
If neither the holdtime interval nor the keepalive interval is configured as 0, the holdtime interval must be at least three times the keepalive interval. The configured timers apply to all IPv6 BGP peers, but they become valid for an IPv6 BGP peer only after the relevant IPv6 BGP connection is reset. After this command is executed, no peer connection is closed at once. The configured hold time is used for negotiation when a peer relationship is reestablished.
