Syntax rip input undo rip input Default An interface is enabled to receive RIP messages. Views Interface view Predefined user roles network-admin Examples # Disable VLAN-interface 10 from receiving RIP messages.
Usage guidelines When a valid RIP route is received, the system adds a metric to it and then installs it into the routing table. The metric of the route received on the configured interface is then increased. If the sum of the additional metric and the original metric is greater than 16, the metric of the route will be 16.
value: Add 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. If a routing policy is referenced with the route-policy keyword, the following operations can be performed: • Routes matching the policy is added with the metric specified in the apply cost command configured in the policy.

Examples # Configure the hello interval on VLAN-interface as 20 seconds.
Related commands ospf timer hello ospf timer retransmit Use ospf timer retransmit to set the LSA retransmission interval on an interface. Use undo ospf timer retransmit to restore the default. Syntax ospf timer retransmit interval undo ospf timer retransmit Default The LSA retransmission interval is 5 seconds on an interface. Views Interface view Predefined user roles network-admin Parameters interval: Specifies the LSA retransmission interval in the range of 1 to 3600 seconds.
Predefined user roles network-admin Parameters seconds: Specifies the LSA transmission delay in the range of 1 to 3600 seconds. Usage guidelines Each LSA in the LSDB has an age that is incremented by 1 every second, but the age does not change during transmission. Adding a transmission delay into the age time is important in low speed networks. Examples # Set the LSA transmission delay to 3 seconds on VLAN-interface 10.
The cost set with the peer command applies only to P2MP neighbors. If no cost is specified, the cost to the neighbor equals the local interface's cost. A router uses the priority set with the peer command to determine whether to send a hello packet to the neighbor rather than for DR election. The DR priority set with the ospf dr-priority command is used for DR election. Examples # Specify the neighbor 1.1.1.1. system-view [Sysname] ospf 100 [Sysname-ospf-100] peer 1.1.1.
# Use a routing policy to set a preference of 100. system-view [Sysname] ip prefix-list test index 10 permit 100.1.1.0 24 [Sysname] route-policy pre permit node 10 [Sysname-route-policy-pre-10] if-match ip address prefix-list test [Sysname-route-policy-pre-10] quit [Sysname] ospf 100 [Sysname-ospf-100] preference route-policy pre 100 reset ospf counters Use reset ospf counters to clear OSPF statistics.
• Starts a new round of DR/BDR election. • Does not remove previous OSPF configurations. The system prompts you to select whether to reset OSPF process upon execution of this command. Examples # Reset all OSPF processes. reset ospf process Reset OSPF process? [Y/N]:y reset ospf redistribution Use reset ospf redistribution to restart route redistribution.
Usage guidelines RFC 1583 specifies a different method than RFC 2328 for selecting the best route from multiple AS external routes destined for the same network. Using this command makes them compatible. If RFC 2328 is compatible with RFC 1583, the intra-area route in the backbone area is preferred. If not, the intra-area route in the non-backbone area is preferred to reduce the burden of the backbone area. Examples # Disable compatibility with RFC 1583.

Use undo snmp trap rate-limit to restore the default. Syntax snmp trap rate-limit interval trap-interval count trap-number undo snmp trap rate-limit Default OSPF outputs 7 traps in 10 seconds. Views OSPF view Predefined user roles network-admin Parameters trap-interval: Specifies the trap output interval in the range of 1 to 60 seconds. trap-number: Specifies the number of output traps in a specific time, in the range of 0 to 300. Examples # Configure OSPF to output 10 traps in 5 seconds.
Usage guidelines Based on the LSDB, an OSPF router uses SPF to calculate a shortest path tree with itself as the root. OSPF uses the shortest path tree to determine the next hop to a destination. By adjusting the SPF calculation interval, you can prevent bandwidth and router resources from being over-consumed due to frequent topology changes. When network changes are not frequent, OSPF performs SPF calculations at the minimum-interval.

Views IS-IS view 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.

Use undo isis authentication-mode to remove the configuration.
For two routers to become neighbors, the authentication mode and password at both ends must be identical. For security purposes, all passwords, including passwords configured in plain text, are saved in cipher text. If you configure a password without specifying a level, the password applies to both Level-1 and Level-2. If neither ip nor osi is specified, the OSI-related fields in LSPs are checked.
Use undo isis circuit-level to restore the default.

Predefined user roles network-admin Usage guidelines Perform this configuration only for a broadcast network with only two attached routers. Interfaces with different network types operate differently. For example, broadcast interfaces must elect a DIS and flood CSNP packets to synchronize the LSDBs, and P2P interfaces do not need to elect a DIS, and use a different LSDB synchronization mechanism.
[Sysname-Vlan-interface10] isis cost 5 level-2 isis dis-name Use isis dis-name to configure a name for a DIS to represent the pseudo node on a broadcast network. Use undo isis dis-name to restore the default. Syntax isis dis-name symbolic-name undo isis dis-name Default No name is configured for the DIS. Views Interface view Predefined user roles network-admin Parameters symbolic-name: Specifies a DIS name, a string of 1 to 64 characters.
Parameters value: Specifies a DIS priority in the range of 0 to 127. level-1: Applies the DIS priority to Level-1. level-2: Applies the DIS priority to Level-2. Usage guidelines If neither level-1 nor level-2 is specified, the DIS priority applies to both Level-1 and Level-2. On an IS-IS broadcast network, a router must be elected as the DIS at each routing level. Specify a DIS priority at a level for an interface. The greater the interface’s priority is, the more likelihood it becomes the DIS.

Views Interface view Predefined user roles network-admin Parameters seconds: Specifies on the DIS of a broadcast network the interval in seconds for sending CSNP packets, ranging from 1 to 600. level-1: Applies the interval to Level-1. level-2: Applies the interval to Level-2. Usage guidelines If no level is specified, the CSNP interval applies to both Level-1 and Level-2. This command only applies to the DIS of a broadcast network, which sends CSNP packets periodically for LSDB synchronization.
Usage guidelines Level-1 and Level-2 hello packets are sent independently on a broadcast network, so you need to specify an interval for each level. On a P2P link, Level-1 and Level-2 packets are both sent in P2P hello packets, and you need not specify an interval for each level. You can configure keywords level-1 and level-2 only on broadcast interfaces. Before you do that, enable IS-IS on the interface. The shorter the interval, the more system resources will be occupied.
Level-1 and Level-2 hello packets are sent independently on a broadcast network, so you need to specify a hello multiplier for each level. On a P2P link, Level-1 and Level-2 packets are both sent in P2P hello packets, and you need not specify Level-1 or Level-2. You can configure keywords level-1 and level-2 only on broadcast interfaces. Before doing that, enable IS-IS on the interface. If no level is specified, the hello multiplier applies to the current level.

Use undo bestroute as-path-neglect to configure BGP to consider the AS_PATH during best route selection. Syntax bestroute as-path-neglect undo bestroute as-path-neglect Default BGP considers the AS_PATH during best route selection.
Usage guidelines By default, BGP does not compare MEDs for routes from the same AS. When a router learns a new route, it compares the route with the optimal route in its BGP routing table. If the new route is more optimal, it becomes the optimal route in the BGP routing table. In this way, route learning sequence might affect optimal route selection. With the bestroute compare-med command configured, the router puts routes received from the same AS into a group.
Usage guidelines This command enables BGP to compare the MEDs of routes received from confederation peers. However, if a route received from a confederation peer has an AS number that does not belong to the confederation, BGP does not compare the route with other routes. For example, a confederation has three AS numbers 65006, 65007, and 65009. BGP receives three routes from different confederation peers.
Parameters as-number: Specifies a local AS by its number in the range of 1 to 4294967295. Usage guidelines A router can reside in only one AS, so the router can run only one BGP process.

The multi-protocol extension function enables BGP to advertise and receive routing information for various protocols (for example, IPv6 routing information). If both the peer capability-advertise conventional and peer capability-advertise route-refresh commands are executed, the last configuration takes effect. Examples # In BGP view, disable multi-protocol extension and route refresh for peer 1.1.1.1. system-view [Sysname] bgp 100 [Sysname-bgp] peer 1.1.1.1 as-number 100 [Sysname-bgp] peer 1.1.
Usage guidelines The route refresh function enables BGP to send and receive Route-refresh messages. BGP uses the route refresh function to implement BGP session soft-reset. After a policy is modified, the router advertises a Route-refresh message to the peers. The peers resend their routing information to the router. After receiving the routing information, the router filters the routing information by using the new policy.

Examples # Use IPv6 prefix list my-prefix-list to filter inbound Inter-Area-Prefix-LSAs, and use IPv6 ACL 2000 to filter outbound Inter-Area-Prefix-LSAs in OSPF Area 1. system-view [Sysname] ospfv3 1 [Sysname-ospfv3-1] area 1 [Sysname-ospfv3-1-area-0.0.0.1] filter prefix-list my-prefix-list import [Sysname-ospfv3-1-area-0.0.0.1] filter 2000 export filter-policy export (OSPFv3 view) Use filter-policy export to configure OSPFv3 to filter redistributed routes.
Using the filter-policy export command filters only routes redistributed by the import-route command. If the import-route command is not configured to redistribute routes from other protocols and other OSPFv3 processes, use of the filter-policy export command does not take effect. Examples # Use IPv6 prefix list abc to filter redistributed routes.
route-policy route-policy-name: Specifies a routing policy by its name, a case-sensitive string of 1 to 63 characters, to filter inbound routes. Usage guidelines To reference an advanced ACL (with a number from 3000 to 3999) in the command, configure the ACL in one of the following ways: • To deny/permit a route with the specified destination, use rule [ rule-id ] { deny | permit } ipv6 source sour sour-prefix.
Usage guidelines To prevent service interruption after a master/backup switchover, a GR Restarter running OSPFv3 must complete the following tasks: • Keep the GR Restarter forwarding entries stable during reboot. • Establish all adjacencies and obtain complete topology information after reboot. Examples # Enable the GR capability for OSPFv3 process 1.
Use undo graceful-restart helper strict-lsa-checking to disable strict LSA checking for the GR Helper. Syntax graceful-restart helper strict-lsa-checking undo graceful-restart helper strict-lsa-checking Default Strict LSA checking for the GR Helper is disabled. Views OSPFv3 view Predefined user roles network-admin Usage guidelines With GR Helper enabled, when an LSA change on the GR Helper is detected, the GR Helper device exits the GR Helper mode.
Examples # Configure the GR restart interval for OSPFv3 process 1 as 100 seconds. system-view [Sysname] ospfv3 1 [Sysname-ospfv3-1] graceful-restart interval 100 Related commands ospfv3 timer dead import-route (OSPFv3 view) Use import-route to redistribute routes. Use undo import-route to disable route redistribution.
an internal router to a Type-2 external route’s destination equals the cost from the ASBR to the Type-2 external route's destination. The import-route command cannot redistribute default routes. The import-route bgp4+ command redistributes only EBGP routes. The import-route bgp4+ allow-ibgp command redistributes both EBGP and IBGP routes, and might cause routing loops. Therefore, use it with caution.
lsa-generation-interval Use lsa-generation-interval to configure the OSPFv3 LSA generation interval. Use undo lsa-generation-interval to restore the default. Syntax lsa-generation-interval maximum-interval [ minimum-interval [ incremental-interval ] ] undo lsa-generation-interval Default The maximum interval is 5 seconds, the minimum interval is 0 milliseconds, and the incremental interval is 0 milliseconds.
Syntax maximum load-balancing maximum undo maximum load-balancing Views OSPFv3 view Predefined user roles network-admin Parameters maximum: Specifies the maximum number of ECMP routes. When the maximum number is 1, OSPFv3 does not perform load balancing. Usage guidelines The value range for the maximum argument and the default setting depend on the max-ecmp-num command.
vpn-instance vpn-instance-name: Specifies an MPLS L3VPN instance by its name, a case-sensitive string of 1 to 31 characters. If no VPN is specified, the OSPFv3 process runs on the public network. Usage guidelines Specify a router ID for the OSPFv3 process. Otherwise, the OSPFv3 process cannot generate LSAs. Examples # Enable OSPFv3 process 120 and configure the Router ID as 1.1.1.1. system-view [Sysname] ospfv3 120 [Sysname-ospfv3-120] router-id 1.1.1.
Default BFD for OSPFv3 is disabled. Views Interface view Predefined user roles network-admin Parameters instance-id: Specifies an instance by its ID in the range of 0 to 255. The default is 0. Usage guidelines BFD provides a mechanism to quickly detect the connectivity of links between OSPFv3 neighbors, improving the convergence speed of OSPFv3. OSPFv3 uses BFD to implement bidirectional control detection. Examples # Enable BFD on VLAN-interface 11 in instance 1.
[Sysname-Vlan-interface10] ospfv3 cost 33 instance 1 ospfv3 dr-priority Use ospfv3 dr-priority to set the router priority for an interface in an instance. Use undo ospfv3 dr-priority to restore the default.

Views Interface view Predefined user roles network-admin Parameters priority: Specifies a router priority in the range of 0 to 255.
Parameters instance-id: Specifies an instance by its ID in the range of 0 to 255. The default is 0. Usage guidelines A neighbor relationship can be established only if the interface's MTU is the same as that of the peer. Examples # Configure VLAN-interface 10 that belongs to instance 1 to ignore MTU check during DD packet exchange.
directly connected, configure the P2MP network type so that the two routers can exchange routing information through another router. When the network type of an interface is NBMA or P2MP unicast, you must use the peer command to specify the neighbor. When the network type of an interface is P2MP unicast, all OSPF packets are unicast by the interface. Examples # Configure the OSPFv3 network type for VLAN-interface 20 as NBMA.
ospfv3 timer dead Use ospfv3 timer dead to configure the OSPFv3 neighbor dead time. Use undo ospfv3 timer dead to restore the default. Syntax ospfv3 timer dead seconds [ instance instance-id ] undo ospfv3 timer dead [ instance instance-id ] Default The OSPFv3 neighbor dead time is 40 seconds for P2P and broadcast interfaces, and is 120 seconds for P2MP and NBMA interfaces.
Views Interface view Predefined user roles network-admin Parameters seconds: Specifies the hello 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 The shorter the hello interval is, the faster the topology converges and the more resources are consumed. Make sure the hello interval on two neighboring interfaces is the same. Examples # Configure the hello interval as 20 seconds for VLAN-interface 10.
system-view [Sysname] interface vlan-interface 10 [Sysname-Vlan-interface10] ospfv3 timer poll 120 Related commands ospfv3 timer hello ospfv3 timer retransmit Use ospfv3 timer retransmit to configure the LSA retransmission interval for an interface. Use undo ospfv3 timer retransmit to restore the default. Syntax ospfv3 timer retransmit seconds [ instance instance-id ] undo ospfv3 timer retransmit [ instance instance-id ] Default The interval defaults to 5 seconds.
Default The transmission delay is 1 second. Views Interface view Predefined user roles network-admin 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. The default is 0. Usage guidelines Each LSA in the LSDB has an age that is incremented by 1 every second, but the age does not change during transmission.
Usage guidelines If multiple routing protocols find multiple routes to the same destination, the router uses the route found by the protocol with the highest preference. Examples # Set a preference of 150 for OSPFv3 routes. system-view [Sysname] OSPFv3 [Sysname-OSPFv3-1] preference 150 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.
router-id Use router-id to configure a router ID. Use undo router-id to remove the configured router ID. Syntax router-id router-id undo router-id Default No router ID is configured. Views OSPFv3 view Predefined user roles network-admin Parameters router-id: Specifies a router ID, in IPv4 address format. Usage guidelines The router ID is the unique identifier for the device to run OSPFv3 in the AS. An OSPFv3 process cannot run without a router ID. Different processes must have different router IDs.
Predefined user roles network-admin Parameters maximum-interval: Specifies the maximum OSPFv3 route calculation interval in the range of 1 to 60 seconds. minimum-interval: Specifies the minimum OSPFv3 route calculation interval in the range of 10 to 60000 milliseconds. incremental-interval: Specifies the incremental OSPFv3 route calculation interval in the range of 10 to 60000 milliseconds.
no-summary: Enables the ABR of a stub area to advertise only a default route in an Inter-Area-Prefix-LSA into the stub area. No AS-external-LSA, Inter-Area-Prefix-LSA, or other Inter-Area-Router-LSA is advertised in the area. The stub area of this kind is also known as a "totally stub area." Usage guidelines To remove the no-summary configuration on an 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 For a non-backbone area without a direct connection to the backbone area or for a backbone area that cannot maintain connectivity, you can use the vlink-peer command to create logical links. 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.

Usage guidelines BGP routing updates contain an AS_PATH attribute field that identifies the ASs through which the routes have passed. An AS path regular expression, for example, ^200. *100$, matches the AS_PATH attribute that starts with AS 200 and ends with AS 100. For the meanings of special characters used in regular expressions, see Fundamentals Configuration Guide. Examples # Create AS path list 1 to permit routes whose AS_PATH attribute starts with 10.
adv-comm-list-name: Specifies the advanced community list name, a case-sensitive string of 1 to 63 characters that cannot comprise only letters. adv-comm-list-num: Specifies the advanced community list number in the range of 100 to 199. regular-expression: Specifies a regular expression for the advanced community list, a string of 1 to 63 characters. For more information about regular expressions, see Fundamentals Configuration Guide. deny: Specifies the match mode for the community list as deny.
Default No extended community list is defined. Views System view Predefined user roles network-admin Parameters ext-comm-list-number: Specifies a number for the extended community list, in the range of 1 to 199. deny: Specifies the match mode for the extended community list as deny. permit: Specifies the match mode for the extended community list as permit. { rt route-target }&<1-32>: Specifies the RT extended community attribute, a string of 3 to 21 characters.
Predefined user roles network-admin Parameters route-policy-name: Specifies a name for the routing policy, a case-sensitive string of 1 to 63 characters. deny: Specifies the deny match mode for the routing policy node. If a route meets all the if-match clauses of the node, it is denied without matching against the next node. If not, it matches against the next node. permit: Specifies the permit match mode for the routing policy node.
