If the outgoing interface is a point-to-point interface, a PPP serial interface for example, you can specify only the outgoing interface. You do not need to change the configuration of the route even if the peer address is changed. If the outgoing interface is an NBMA interface or point-to-multipoint (P2MP) interface, an X.
undo ip route-static default-preference Default The default preference of static routes is 60. Views System view Default command level 2: System level Parameters default-preference-value: Specifies a default preference for static routes, in the range of 1 to 255. Usage guidelines If no preference is specified for a static route, the default preference is used. When the default preference is re-configured, it applies to newly added static routes only.
Usage guidelines Configuring static route FRR needs to reference a routing policy, which specifies a backup next hop with the apply fast-reroute backup-interface command. For more information about the command and routing policy configurations, see Layer 3—IP Routing Configuration Guide. Static route FRR takes effect only for static routes that have both the outgoing interface and next hop specified. Do not use static route FRR and BFD (for static route) at the same time.

host-route Use host-route to enable host route reception. Use undo host-route to disable host route reception. Syntax host-route undo host-route Default Receiving host routes is enabled. Views RIP view Default command level 2: System level Usage guidelines In some cases, a router might receive many host routes from the same network segment. These routes are not helpful for routing and occupy a large amount of network resources. Use undo host-route to disable receiving of host routes.
Parameters protocol: Specifies a routing protocol from which to redistribute routes. It can be bgp, direct, isis, ospf, rip, or static. process-id: Specifies a process by its ID in the range of 1 to 65535. The default is 1. This argument is available only when the protocol is isis, rip, or ospf. all-processes: Enables route redistribution from all the processes of a protocol. This keyword takes effect only when the protocol is rip, ospf, or isis.
Views RIP view Default command level 2: System level Parameters number: Specifies the maximum number of ECMP routes, in the range of 1 to 8. Examples # Specify the maximum number of ECMP routes as 2. system-view [Sysname] rip [Sysname-rip-1] maximum load-balancing 2 network Use network to enable RIP on the interface attached to the specified network. Use undo network to disable RIP on the interface attached to the specified network.
output-delay Use output-delay to configure the maximum RIP packets that can be sent at the specified interval for all interfaces under the RIP process. Use undo output-delay to restore the default. Syntax output-delay time count count undo output-delay Default An interface sends up to three RIP packets every 20 milliseconds. Views RIP view Default command level 2: System level Parameters time: Specifies the RIP packet sending interval in the range of 10 to 100 milliseconds.
Usage guidelines You need not use the peer ip-address command when the neighbor is directly connected; otherwise the neighbor might receive both the unicast and multicast (or broadcast) of the same routing information. Examples # Specify to send unicast updates to peer 202.38.165.1. system-view [Sysname] rip 1 [Sysname-rip-1] peer 202.38.165.1 preference Use preference to specify the preference for RIP routes. Use undo preference to restore the default.
reset rip process Use reset rip process to reset the specified RIP process. Syntax reset rip process-id process Views User view Default command level 1: Monitor level Parameters process-id: Specifies a RIP process by its ID in the range of 1 to 65535. Usage guidelines After you execute the command, the system prompts you to confirm a reset of the RIP process. Examples # Reset RIP process 100.
Syntax rip [ process-id ] [ vpn-instance vpn-instance-name ] undo rip [ process-id ] [ vpn-instance vpn-instance-name ] Default No RIP process runs. Views System view Default command level 2: System level Parameters process-id: Specifies a RIP process by its ID in the range of 1 to 65535. The default is 1. vpn-instance vpn-instance-name: Specifies an MPLS L3VPN. vpn-instance-name is a case-sensitive string of 1 to 31 characters. If no VPN is specified, the RIP process will run under the public network.
rfc2082: Uses the message format defined in RFC 2082. cipher: Sets a ciphertext authentication key or password. If this keyword is not specified, you set a plaintext authentication key or password. key-string: Specifies the MD5 key string. This argument is case sensitive. It must be a plaintext string of 1 to 16 characters, or a ciphertext string of 33 to 53 characters. key-id: Specifies the MD5 key number in the range of 1 to 255. rfc2453: Uses the message format defined in RFC 2453 (IETF standard).
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 GigabitEthernet 2/1/1.
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.

Usage guidelines If an interface receives no hello packet from a neighbor within the dead interval, the interface considers the neighbor down. The dead interval on an interface is at least four times the hello interval.
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 on an interface as 20 seconds. system-view [Sysname] interface GigabitEthernet 2/0/0 [Sysname-GigabitEthernet2/0/0] ospf timer hello 20 Related commands ospf timer dead ospf timer poll Use ospf timer poll to set the poll interval on an NBMA interface.
Use undo ospf timer retransmit to restore the default. Syntax ospf timer retransmit interval undo ospf timer retransmit Default The interval defaults to 5s. Views Interface view Default command level 2: System level Parameters interval: Specifies the LSA retransmission interval in seconds, in the range of 1 to 3600. Usage guidelines After an interface sends an LSA, it waits for an acknowledgement packet.
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. It is necessary to add a transmission delay into its age time, which is important for low speed networks. Examples # Set the LSA transmission delay to 3 seconds on an interface. system-view [Sysname] interface GigabitEthernet 2/0/0 [Sysname-GigabitEthernet2/0/0] ospf trans-delay 3 peer Use peer to specify a neighbor, and the DR priority of the neighbor.
[Sysname] ospf 100 [Sysname-ospf-100] peer 1.1.1.1 Related commands ospf dr-priority preference Use preference to set the preference of OSPF routes. Use undo preference to restore the default. Syntax preference [ ase ] [ route-policy route-policy-name ] value undo preference [ ase ] Default The preference of OSPF internal routes defaults to 10, and the preference of OSPF external routes defaults to 150.
Syntax reset ospf [ process-id ] counters [ neighbor [ interface-type interface-number ] [ router-id ] ] Views User view Default command level 1: Monitor level Parameters process-id: Clears the statistics of an OSPF process specified by its ID in the range of 1 to 65535. neighbor: Clears neighbor statistics. interface-type interface-number: Clears the statistics of the neighbor connected to the specified interface. router-id: Clears the statistics of the specified neighbor.
• 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 Warning : Reset OSPF process? [Y/N]:Y # Reset all OSPF processes using GR. reset ospf process graceful-restart Warning : Reset OSPF process? [Y/N]:Y reset ospf redistribution Use reset ospf redistribution to restart route redistribution.
Default command level 2: System level Usage guidelines RFC 1583 and RFC 2328 use different rules for selecting the best route among multiple AS external routes destined for the same network. Using this command can make 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.
Examples # Configure a global router ID. system-view [Sysname] router id 1.1.1.1 silent-interface (OSPF view) Use silent-interface to disable an interface or all interfaces from r sending OSPF 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 can send OSPF packets.

Use undo spf-schedule-interval to restore the default. Syntax spf-schedule-interval maximum-interval [ minimum-interval [ incremental-interval ] ] undo spf-schedule-interval Default The interval defaults to 5 seconds. Views OSPF view Default command level 2: System level Parameters maximum-interval: Specifies the maximum OSPF route calculation interval in seconds, in the range of 1 to 60.
Default No area is stub area. Views OSPF area view Default command level 2: System level Parameters default-route-advertise-always: Usable only on a stub ABR. With this keyword, the ABR advertises a default route in a Type-3 LSA into the stub area regardless of whether FULL-state neighbors exist in the backbone area. Without this keyword, the ABR advertises a default route in a Type-3 LSA into the stub area only when at least one FULL-state neighbor exists in the backbone 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.
vlink-peer (OSPF area view) Use vlink-peer to configure a virtual link. Use undo vlink-peer to remove a virtual link.
• A so small retransmission interval will lead to unnecessary retransmissions. A big value is appropriate for a low speed link. • You need to specify an appropriate transmission delay with the trans-delay keyword. • You can specify either MD5/HMAC-MD5 authentication or simple authentication for a virtual link. For MD5/HMAC-MD5 authentication, you can configure multiple keys by executing this command multiple times, and each command must have a unique key ID and key string.
IS-IS configuration commands area-authentication-mode Use area-authentication-mode to specify the area authentication mode and a password. Use undo area-authentication-mode to restore the default. Syntax area-authentication-mode { md5 | simple } [ cipher ] password [ ip | osi ] undo area-authentication-mode Default No area authentication is configured. Views IS-IS view Default command level 2: System level Parameters md5: Specifies the MD5 authentication mode.

Related commands • bandwidth-reference • cost-style bandwidth-reference (IS-IS view) Use bandwidth-reference to set the bandwidth reference value for automatic link cost calculation. Use undo bandwidth-reference to restore the default. Syntax bandwidth-reference value undo bandwidth-reference Default The bandwidth reference value is 100 Mbps. Views IS-IS view Default command level 2: System level Parameters value: Specifies the bandwidth reference value in Mbps, in the range of 1 to 2147483648.
Default command level 2: System level Parameters value: Link cost value. The value range varies with cost styles. • For styles narrow, narrow-compatible, and compatible, the cost value is in the range of 0 to 63. • For styles wide and wide-compatible, the cost value is in the range of 0 to 16777215. When the cost value is 16777215, the neighbor TLV generated on the link can only be used to transmit relevant TE information, but cannot be used to calculate routes.
narrow-compatible: Receives both narrow and wide cost style packets, but sends only narrow cost style packets. wide-compatible: Receives both narrow and wide cost style packets, but sends only wide cost style packets. relax-spf-limit: Allows receiving routes with a cost greater than 1023. If this keyword is not specified, any route with a cost higher than 1023 is discarded. This keyword is only available when compatible or narrow-compatible is included.
The Level-1 default route is advertised to other routers in the same area, and the Level-2 default route is advertised to all the Level-2 and Level-1-2 routers. If no topology is specified, the default route is advertised in the base topology. Using the apply isis level-1 command in routing policy view will generate a default route in a Level-1 LSP. Using the apply isis level-2 command in routing policy view will generate a default route in a Level-2 LSP.

Usage guidelines Whether a password should use ip or osi is not affected by the actual network environment. The password in the specified mode is inserted into all outgoing hello packets and is used for authenticating the incoming hello packets. Only the authentication succeeds can the neighbor relationship be formed. For two routers to become neighbors, the same authentication mode and password must be specified at both ends.

Use undo isis enable to disable IS-IS. Syntax isis enable [ process-id ] undo isis enable Default No IS-IS routing process is enabled on an interface. Views Interface view Default command level 2: System level Parameters process-id: Specifies an IS-IS process by its ID in the range of 1 to 65535.
undo isis mesh-group Default An interface does not belong to any mesh group. Views Interface view Default command level 2: System level Parameters mesh-group-number: Specifies a mesh group by its number in the range of 1 to 4294967295. mesh-blocked: Blocks the interface, which sends LSPs only after receiving LSP requests. Usage guidelines For an interface not in a mesh group, it follows the normal process to flood the received LSPs to other interfaces.
Default command level 2: System level Parameters process-id: Specifies an IS-IS process by its ID in the range of 1 to 65535. Examples # Bind MIBs with IS-IS process 100. system-view [Sysname] isis mib-binding 100 isis multiple-topology ipv4-unicast Use isis multiple-topology ipv4-unicast to enable an IPv4 unicast topology on an IS-IS interface. Use undo isis multiple-topology ipv4-unicast to cancel the configuration.
Use undo isis peer-ip-ignore to restore the default. Syntax isis peer-ip-ignore undo isis peer-ip-ignore Default The PPP interface checks the peer's IP address upon receiving a hello packet. Views Interface view 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.
[Sysname-GigabitEthernet4/0/1] isis silent isis small-hello NOTE: This command is not available in loopback interface view. Use isis small-hello to configure the interface to send small hello packets without CLVs. Use undo isis small-hello to restore the default. 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 GigabitEthernet 4/0/1 interface to send small Hello packets.
Default command level 2: System level Parameters seconds: Specifies on the DIS of a broadcast network the interval for sending CSNP packets. The value range is 1 to 600 seconds. level-1: Applies the interval to Level-1. level-2: Applies the interval to Level-2. Usage guidelines This command only applies to the DIS of a broadcast network, which sends CSNP packets periodically for LSDB synchronization. If no level is specified, the CSNP interval applies to both Level-1 and Level-2.
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 of the two levels. 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 of the two levels. You can configure keywords level-1 and level-2 only on broadcast interfaces. Before you do that, enable IS-IS on the interface.
Usage guidelines With the IS-IS hello multiplier configured, a router can uses hello packets to notify its neighbor router of the adjacency hold time (hello multiplier times hello interval). If the neighbor router receives no hello packets from this router within the hold time, it declares the adjacency down. You can adjust the adjacency hold time by changing the hello multiplier or the hello interval on an interface.

BGP configuration commands For more information about routing policy configuration commands in this document, see "Routing policy configuration commands." aggregate Use aggregate to create a summary route in the BGP routing table. Use undo aggregate to remove a summary route.
Keywords Function detail-suppressed This keyword does not suppress the summary route, but it suppresses the advertisement of all the more specific routes. To summarize only some specific routes, use the peer filter-policy command. suppress-policy Used to create a summary route and suppress the advertisement of some summarized routes. If you want to suppress some routes selectively and leave other routes still advertised, use the if-match clause of the route-policy command.
Usage guidelines During BGP network optimization or upgrade, each change of BGP routing policies triggers route refreshing, which burdens BGP routers and the network. To resolve this issue, use the undo auto-refresh enable command to disable the policies from automatically taking effect. After modifying all policies, execute the refresh bgp or reset bgp command to make the new policies take effect. Examples # Disable BGP routing policies from automatically taking effect.

Usage guidelines Routes learned from a peer have an initial preferred value. Among multiple routes that have the same destination/mask and are learned from different peers, the one with the greatest preferred value is selected as the route to the destination. If you both reference a routing policy and use the peer { group-name | ip-address } preferred-value value command to set a preferred value for routes from a peer, the routing policy sets the specified preferred value for routes matching it.
Usage guidelines The command does not take effect if the BGP update has both public and private AS numbers. The value range for the private AS number is 64512 to 65535.

Views Interface view Default command level 2: System level Parameters priority: Specifies a DR priority in the range of 0 to 255. 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 Serial2/2/0. system-view [Sysname] interface serial 2/2/0 [Sysname-Serial2/2/0] ospfv3 ipsec-policy policy001 instance 1 ospfv3 mtu-ignore Use ospfv3 mtu-ignore to configure an interface to ignore MTU check during DD packet exchange. Use undo ospfv3 mtu-ignore to restore the default.
• 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. By default, an OSPFv3 interface whose network type is P2MP sends packets in multicast mode.
Examples # Specify the neighbor fe80::1111. system-view [Sysname] interface gigabitethernet 2/1/1 [Sysname-Gigabitethernet2/1/1] 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.
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. Views Interface view Default command level 2: System level Parameters seconds: Specifies the interval between hello packets, 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. Examples # Configure the LSA retransmission interval on an interface in instance 1 as 12 seconds.
Default The transmission delay is 1s. Views Interface view Default command level 2: System level Parameters seconds: Specifies the transmission delay in seconds, in the range of 1 to 3600. instance-id: Specifies an instance by its ID in the range of 0 to 255. The default is 0. Usage guidelines As LSAs are aged in the LSDB (incremented by 1 every second) but not aged on transmission, it is necessary to add a delay time to the age time before sending a LSA.
Usage guidelines The smaller the value is, the higher the preference is. A router might run multiple routing protocols. Each protocol has a preference. When several routing protocols find multiple routes to the same destination, the route found by the protocol with the highest preference is selected. Examples # Set a preference of 150 for OSPFv3 routes. system-view [Sysname] ospfv3 1 [Sysname-OSPFv3-1] preference 150 router-id Use router-id to configure the OSPFv3 router ID.
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 interface-type interface-number: Specifies an interface by its type and number. all: Specifies all interfaces.
Default command level 2: System level Parameters delay-interval: Specifies the interval between when OSPFv3 receives a topology change and when it starts SPF calculation. The value range is 0 to 65535 seconds. hold-interval: Specifies the hold interval between two consecutive SPF calculations. The value range is 0 to 65535 seconds. Usage guidelines An OSPFv3 router works out a shortest path tree with itself as root based on the LSDB and decides on the next hop to a destination network according the tree.
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.
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 10.0.0.0 [Sysname-ospfv3-1-area-10.0.0.0] vlink-peer 10.110.0.

IPv6 BGP configuration commands For more information about routing policy configuration commands in this document, see "Routing policy configuration commands." aggregate (IPv6 address family view) Use aggregate to create an IPv6 summary route in the IPv6 BGP routing table. Use undo aggregate to remove an IPv6 summary route.
Keywords Function detail-suppressed This keyword does not suppress the summary route, but it suppresses the advertisement of all the more specific routes. To summarize only some specific routes, use the peer filter-policy command. suppress-policy Used to create a summary route and suppress the advertisement of some summarized routes. If you want to suppress some routes selectively and leave other routes still advertised, use the if-match clause of the route-policy command.
If you do not specify the ibgp or the ebgp keyword, this command enables load sharing for all IPv6 BGP routes. You cannot execute the balance number command after you specify the ibgp or the ebgp keyword. To execute the balance number command, use the undo command to remove the previous configuration, and vice versa. Examples # Set the number of IPv6 BGP ECMP routes to 2.

Syntax router-id router-id undo router-id Views BGP view Default command level 2: System level Parameters router-id: 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.
