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.
RIP configuration commands checkzero Use checkzero to enable zero field check on RIPv1 messages. Use undo checkzero to disable zero field check. Syntax checkzero undo checkzero Default The zero field check function is enabled. Views RIP view Default command level 2: System level Usage guidelines After the zero field check is enabled, the router discards RIPv1 messages in which zero fields are non-zero. If all messages are trusted, disable this feature to reduce the processing time of the CPU.
Default command level 2: System level Parameters value: Specifies a default metric for redistributed routes, in the range of 0 to 16. Usage guidelines When you use the import-route command to redistribute routes from other protocols without specifying a metric, the metric specified by the default cost command applies.

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.
Views Interface view Default command level 2: System level Examples # Enable GigabitEthernet 2/1/1 to receive RIP messages. system-view [Sysname] interface gigabitethernet 2/1/1 [Sysname-GigabitEthernet2/1/1] rip input rip metricin Use rip metricin to configure the interface to add a metric to the routes it receives.

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.

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.

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.
Configuring IPv6 policy-based routing Introduction to IPv6 policy-based routing What is policy-based routing Different from destination-based routing, policy-based routing (PBR) uses user-defined policies to route packets based on the source address, packet length, and other criteria. A policy can specify the output interface, next hop, default output interface, default next hop, and other parameters for packets that match specific criteria such as ACLs or have specific lengths.
Table 102 Priorities and meanings of the apply clauses Clause Meaning Priority apply ipv6-precedence Sets an IP precedence. If configured, this clause will always be executed. apply output-interface and apply ipv6-address next-hop Sets the output interface and sets the next hop. The apply output-interface clause takes precedence over the apply ipv6-address next-hop clause. Only the apply output-interface clause is executed when both are configured.
IPv6 PBR configuration task list Task Remarks Creating an IPv6 node Configuring an IPv6 policy Configuring match criteria for an IPv6 node Required. Defining the actions for an IPv6 node Configuring IPv6 PBR Configuring IPv6 local PBR Required. Configuring IPv6 interface PBR Perform one of the tasks. Configuring an IPv6 policy Creating an IPv6 node Step Command 1. Enter system view. system-view 2. Create an IPv6 policy or policy node and enter IPv6 policy node view.
Step Command Remarks 1. Enter system view. system-view N/A 2. Enter IPv6 policy node view. ipv6 policy-based-route policy-name [ deny | permit ] node node-number Not created by default. 3. Set a preference type or value for permitted IPv6 packets. apply ipv6-precedence { type | value } Optional. 4. Set an output interface for permitted IPv6 packets. apply output-interface interface-type interface-number 5. Set a next hop for permitted IPv6 packets.
Step Command Remarks 1. Enter system view. system-view N/A 2. Apply an IPv6 policy locally. ipv6 local policy-based-route policy-name Not applied by default. Configuring IPv6 interface PBR Configure PBR by applying an IPv6 policy on an interface. IPv6 PBR uses the policy to guide the forwarding of packets received on the interface. You can apply only one policy on an interface. If you perform the ipv6 policy-based-route command multiple times, only the last specified policy takes effect.
IPv6 PBR configuration examples Configuring IPv6 local PBR based on packet type Network requirements As shown in Figure 1, configure IPv6 local PBR on Router A to forward all locally generated TCP packets through Serial 2/2/0. Router A forwards other IPv6 packets according to the routing table. Figure 1 Network diagram Configuration procedure 1. Configure Router A: # Configure ACL 3001 to match TCP packets.

On Host A, Telnet to Router B that is directly connected to Router A. The operation succeeds. On Host A, Telnet to Router C that is directly connected to Router A. The operation fails. Ping Router C from Host A. The operation succeeds. Telnet uses TCP, and ping uses ICMP. The preceding results show that all TCP packets received on GigabitEthernet 2/1/1 of Router A are forwarded through Serial 2/2/0, and other packets are forwarded through Serial 2/2/1.
