Basic IP routing commands The term "interface" in this chapter collectively refers to Layer 3 interfaces, including VLAN interfaces and Layer 3 Ethernet interfaces. You can set an Ethernet port as a Layer 3 interface by using the port link-mode route command (see Layer 2—LAN Switching Configuration Guide). address-family ipv4 Use address-family ipv4 to create a RIB IPv4 address family and enter RIB IPv4 address family view.
Predefined user roles network-admin mdc-admin Examples # Create a RIB IPv6 address family and enter RIB IPv6 address family view. system-view [Sysname] rib [Sysname-rib] address-family ipv6 [Sysname-rib-ipv6] display ip routing-table Use display ip routing-table to display routing table information.

Predefined user roles network-admin mdc-admin Parameters protocol: Specifies a routing protocol from which RIP redistributes 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 the specified protocol. This keyword takes effect only when the protocol is rip, ospf, or isis.
Views RIP view Predefined user roles network-admin mdc-admin Parameters number: Specifies the maximum number of ECMP routes. Usage guidelines The value range for the number argument and the default setting depend on the max-ecmp-num command. If you set the maximum number of ECMP routes to m by using the max-ecmp-num command, the number argument in the maximum load-balancing command is in the range of 1 to m and defaults to m. Examples # Specify the maximum number of ECMP routes as 2.
Usage guidelines RIP runs only on an interface attached to the specified network, which can be configured with a wildcard mask. An interface not on the specified network does not receive or send RIP routes, or advertise its direct routes. For a single RIP process, the network 0.0.0.0 command can enable RIP on all interfaces. If multiple RIP processes exist, the command is not applicable. If a physical interface is attached to multiple networks, you cannot advertise these networks in different RIP processes.
peer Use peer to specify a RIP neighbor in the NBMA network, where routing updates destined for the neighbor are only unicasts and not multicast or broadcast. Use undo peer to remove a RIP neighbor. Syntax peer ip-address undo peer ip-address Default RIP does not unicast updates to any neighbor. Views RIP view Predefined user roles network-admin mdc-admin Parameters ip-address: Specifies the IP address of a RIP neighbor, in dotted decimal notation.

Syntax reset rip process-id statistics Views User view Predefined user roles network-admin network-operator mdc-admin mdc-operator Parameters process-id: Specifies a RIP process by its ID in the range of 1 to 65535. Examples # Clear statistics for RIP process 100.
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 RIP process runs on the public network. 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.
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. Examples # Configure MD5 authentication on VLAN-interface 10 and specify a plaintext key rose in the format defined in RFC 2453.
rip bfd enable destination Use rip bfd enable destination to enable BFD single-hop echo detection for a specific destination. Use undo rip bfd enable to disable BFD for RIP.

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.
Default The maximum length of RIP packets is 512 bytes. Views Interface view Predefined user roles network-admin mdc-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. The supported maximum length of RIP packets varies by vendor.
mdc-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. The metric of the route received on the configured interface is then increased.
Predefined user roles network-admin mdc-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.

Examples # Disable automatic RIPv2 route summarization. system-view [Sysname] rip [Sysname-rip-1] undo summary Related commands • rip summary-address • rip version timers Use timers to configure RIP timers. Use undo timers to restore the default.
• Garbage-collect timer—Specifies the interval from when the metric of a route becomes 16 to when it is deleted from the routing table. During the garbage-collect timer length, RIP advertises the route with a metric of 16. If no update is announced for that route before the garbage-collect timer expires, RIP deletes the route from the routing table. HP recommends not changing the default values of these timers. The timer lengths must be consistent on all routers on the network.
Default No global RIP version is configured. An RIP interface can send RIPv1 broadcasts and receive RIPv1 broadcasts and unicasts, and RIPv2 broadcasts, multicasts, and unicasts. Views RIP view Predefined user roles network-admin mdc-admin Parameters 1: Specifies the RIP version as RIPv1. 2: Specifies the RIP version as RIPv2. RIPv2 messages are multicast.

Use undo graceful-restart to disable OSPF GR. Syntax graceful-restart [ ietf | nonstandard ] [ global | planned-only ] * undo graceful-restart Default OSPF GR is disabled. Views OSPF view Predefined user roles network-admin mdc-admin Parameters ietf: Enables IETF GR. nonstandard: Enables non-IETF GR.
Examples # Enable IETF GR for OSPF process 1. system-view [Sysname] ospf 1 [Sysname-ospf-1] opaque-capability enable [Sysname-ospf-1] graceful-restart ietf # Enable non-IETF GR for OSPF process 1.
graceful-restart helper strict-lsa-checking Use graceful-restart helper strict-lsa-checking to enable strict LSA checking capability for GR helper. Use undo graceful-restart helper strict-lsa-checking to disable strict LSA checking capability for GR helper. Syntax graceful-restart helper strict-lsa-checking undo graceful-restart helper strict-lsa-checking Default Strict LSA checking capability for GR helper is disabled.
Parameters interval-value: Specifies the GR interval in the range of 40 to 1800 seconds. Usage guidelines The value of the GR restart interval cannot be smaller than the maximum OSPF neighbor dead time of all the OSPF interfaces. Otherwise, GR restart might fail. Examples # Configure the GR interval for OSPF process 1 as 100 seconds.
Use undo import-route to disable route redistribution from another routing protocol. Syntax import-route protocol [ process-id | all-processes | allow-ibgp ] [ cost cost | [ cost cost | nssa-only | route-policy route-policy-name | tag tag | type type ] * undo import-route protocol [ process-id | all-processes ] Default OSPF does not redistribute AS-external routes from any other routing protocol.
from 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 external routes. The import-route bgp command redistributes only EBGP routes. Because the import-route bgp allow-ibgp command redistributes both EBGP and IBGP routes and might cause routing loops, use it with caution. Only active routes can be redistributed.
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 of OSPF neighbor state changes. Syntax log-peer-change undo log-peer-change Default The logging of OSPF neighbor state changes is enabled.
Predefined user roles network-admin mdc-admin Parameters interval: Specifies the LSA arrival interval in the range of 0 to 60000 milliseconds. Usage guidelines If an LSA that has the same LSA type, LS ID, originating router ID as the previous LSA is received within the interval, OSPF discards the LSA. This feature helps protect resources from being over consumed due to frequent network changes.
You can configure the interval that OSPF exits overflow state. An interval of 0 indicates that the timer is not started and OSPF does not exit overflow state. Examples # Configure the OSPF exit overflow interval as 10 seconds. system-view [Sysname] ospf 100 [Sysname-ospf-100] lsdb-overflow-interval 10 lsa-generation-interval Use lsa-generation-interval to configure the OSPF LSA generation interval. Use undo lsa-generation-interval to restore the default.
Related commands lsa-arrival-interval lsdb-overflow-limit Use lsdb-overflow-limit to specify the upper limit of external LSAs in the LSDB. Use undo lsdb-overflow-limit to restore the default. Syntax lsdb-overflow-limit number undo lsdb-overflow-limit Default The number of external LSAs is not limited. Views OSPF view Predefined user roles network-admin mdc-admin Parameters number: Specifies the upper limit of external LSAs in the LSDB, in the range of 1 to 1000000.
Parameters maximum: Specifies the maximum number of ECMP routes. No ECMP load balancing is available when the number is set to 1. Usage guidelines The value range for the maximum argument and the default setting depend on the max-ecmp-num command. If you set the maximum number of ECMP routes to m by using the max-ecmp-num command, the maximum argument in the maximum load-balancing command is in the range of 1 to m and defaults to m. Examples # Specify the maximum number of ECMP routes as 2.
Usage guidelines This command enables OSPF on the interface attached to the specified network. The interface's primary IP address must be in the specified network. If only the interface's secondary IP address is in the network, the interface cannot run OSPF. Examples # Specify the interface whose primary IP address is on network 131.108.20.0/24 to run OSPF in Area 2. system-view [Sysname] ospf 100 [Sysname-ospf-100] area 2 [Sysname-ospf-100-area-0.0.0.2] network 131.108.20.0 0.0.0.
the command distributes a default route in a Type-7 LSA into the OSPF routing domain, and the routing policy modifies some values in the Type-7 LSA. type type: Specifies a type for the Type-7 LSA: 1 or 2. If no type is specified, the default type specified by the default type command applies. no-import-route: Used on an NSSA ABR to control the import-route command to not redistribute routes into the NSSA area.
Predefined user roles network-admin mdc-admin Usage guidelines After the opaque LSA advertisement and reception is enabled, OSPF can receive and advertise Type-9, Type-10, and Type-11 opaque LSAs. Examples # Disable opaque LSA advertisement and reception. system-view [Sysname] ospf 100 [Sysname-ospf-100] undo opaque-capability ospf Use ospf to enable OSPF and enter OSPF view. Use undo ospf to disable OSPF.
ospf area Use ospf area to enable OSPF on an interface. Use undo ospf area to remove the configuration.

Syntax ospf dr-priority priority undo ospf dr-priority Default The router priority is 1. Views Interface view Predefined user roles network-admin mdc-admin Parameters priority: Specifies the router priority for the interface, in the range of 0 to 255. Usage guidelines The greater the value, the higher the priority for DR/BDR election.
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. system-view [Sysname] interface vlan-interface 11 [Sysname-Vlan-interface11] undo ospf fast-reroute lfa-backup ospf mib-binding Use ospf mib-binding to bind an OSPF process to MIB. Use undo ospf mib-binding 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 mdc-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. To make them consistent, restore the interfaces' MTU to the default value 0.
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.
Predefined user roles network-admin mdc-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 mdc-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.
Parameters interval: Specifies the LSA retransmission interval in the range of 1 to 3600 seconds. 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.
peer Use peer to specify a neighbor and a DR priority for the neighbor. Use undo peer to remove the configuration. Syntax peer ip-address [ cost value | dr-priority dr-priority ] undo peer ip-address Default No neighbor is specified. Views OSPF view Predefined user roles network-admin mdc-admin Parameters ip-address: Specifies a neighbor by its IP address. cost value: Specifies the cost to reach the neighbor, in the range of 1 to 65535.
Use undo pic to disable OSPF PIC. Syntax pic [ additional-path-always ] undo pic Default OSPF PIC is enabled. Views OSPF view Predefined user roles network-admin mdc-admin Parameters additional-path-always: Allows the indirect suboptimal route as the backup route. Usage guidelines Prefix Independent Convergence (PIC) enables the device to speed up network convergence by ignoring the number of prefixes. PIC applies to only inter-area routes and external routes.
Parameters ase: Sets a preference for OSPF external routes. Without this keyword, the command sets a preference for OSPF internal routes. route-policy route-policy-name: Specifies a routing policy by its name, a case-sensitive string of 1 to 63 characters, to set a preference for the specified routes. value: Specifies the preference value in the range of 1 to 255. The smaller the value, the higher the preference.
Usage guidelines Prefix prioritization enables the device to install prefixes in descending priority order: critical, high, medium, and low. The prefix priorities are assigned through routing policies. When a route is assigned multiple prefix priorities, it uses the highest priority. By default, the 32-bit OSPF host routes have a medium priority and other routes have a low priority. Examples # Use a routing policy to assign the medium priority to the specified route prefixes.
forwarding. If no neighbors exist, the DR also does not advertise the primary IP addresses of interfaces in Router LSAs. Examples # Enable prefix suppression for OSPF process 1. system-view [Sysname] ospf 1 [Sysname-ospf-1] prefix-suppression Related commands ospf prefix-suppression reset ospf counters Use reset ospf counters to clear OSPF statistics.
Usage guidelines If no process is specified, this command restarts all OSPF processes. The reset ospf process command performs the following actions: • Clears all invalid LSAs without waiting for their timeouts. • Makes a newly configured Router ID take effect. • 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.
Default Compatibility with RFC 1583 is enabled. Views OSPF view Predefined user roles network-admin mdc-admin Usage guidelines RFC 1583 specifies a different method than RFC 2328 for selecting the optimal route to a destination in another AS. When multiple routes are available to the ASBR, OSPF selects the optimal route by using the following procedure: 1. Selects the route with the highest preference: { { If RFC 2328 is compatible with RFC 1583, all these routes have equal preference.
Parameters router-id: Specifies the router ID, in the format of an IPv4 address. Usage guidelines OSPF uses a router ID to identify a device. If no router ID is specified, the global router ID is used. If no global router ID is configured, the highest loopback interface IP address 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 (up or down).
To disable a network from receiving and sending OSPF routes, issue the command on the interface connected to the network. Examples # Disable VLAN-interface 10 from receiving and sending OSPF packets. system-view [Sysname] ospf 100 [Sysname-ospf-100] silent-interface vlan-interface 10 snmp-agent trap enable ospf Use snmp-agent trap enable ospf to enable SNMP notifications for OSPF.

Syntax address-family ipv6 [ unicast ] undo address-family ipv6 [ unicast ] Default The BGP IPv6 unicast address family view or BGP-VPN IPv6 unicast address family view is not created.
Syntax advertise-rib-active undo advertise-rib-active Default BGP advertises optimal routes in the BGP routing table, regardless of whether they are optimal in the IP routing table.
Default No summary route is configured. Views BGP IPv4 unicast address family view, BGP-VPN IPv4 unicast address family view, BGP IPv6 unicast address family view Predefined user roles network-admin mdc-admin Parameters ip-address: Specifies a summary address. mask: Specifies a mask for the summary address, in dotted decimal notation. mask-length: Specifies a mask length for the summary address, in the range of 0 to 32. ipv6-address: Specifies an IPv6 summary address.
Table 66 Functions of the keywords Keywords Function as-set Enables the summary route to carry the AS path information of all summarized routes. This feature can help avoid routing loops. However, if many routes are summarized and are changed frequently, do not specify this keyword because this configuration causes the summary route to flap with the more specific routes. attribute-policy Sets attributes except the AS-PATH attribute for the summary route.

When it is set to 1, load balancing is disabled. Usage guidelines Unlike IGP, BGP has no explicit metric for making load balancing decision.
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.
mdc-admin 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.
Predefined user roles network-admin mdc-admin 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.
Views System view Predefined user roles network-admin mdc-admin 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. A router supports 4-byte AS number. Examples # Enable BGP, set the local AS number to 100, and enter BGP view.
[Sysname-bgp] address-family ipv4 unicast [Sysname-bgp-ipv4] compare-different-as-med # In BGP-VPN IPv4 unicast address family view, enable MED comparison for routes from peers in different ASs. system-view [Sysname] bgp 100 [Sysname-bgp] ip vpn-instance vpn1 [Sysname-bgp-vpn1] address-family ipv4 unicast [Sysname-bgp-ipv4-vpn1] compare-different-as-med # In BGP IPv6 unicast address family view, enable MED comparison for routes from peers in different ASs.
Examples # Confederation 9 consists of four sub-ASs numbered 38, 39, 40 and 41. The peer 10.1.1.1 is a member of sub-AS 38. The peer 200.1.1.1 is a member outside of confederation 9, which belongs to AS 98. Confederation 9 looks like one AS (with AS number 9) from the perspective of the peer 200.1.1.1. This example uses a router in sub-AS 41.

This EBGP route is called shortcut route. Use undo network short-cut to cancel the configuration.
By default, the preference of an EBGP route is lower than a local route. If a device has an EBGP route and a local route to reach the same destination, the device does not select the EBGP route. You can use the network shortcut command to configure the EBGP route to have the same preference as the local route so the EBGP route is more likely to become the optimal route. You can use the preference command to modify the preferences for external and local BGP routes.

Usage guidelines This command enables you to temporarily tear down the BGP session to a specific peer or peer group so that you can perform network upgrade and maintenance without needing to delete and reconfigure the peer or peer group. To recover the session, execute the undo peer ignore command. If a session has been established to a peer, executing the peer ignore command for the peer tears down the session and clears all related routing information.
Usage guidelines IMPORTANT: Ignoring the ORIGINATOR_ID attribute might introduce routing loops to the network. Do not use this command to ignore the ORIGINATOR_ID attribute if you are not sure there are no routing loops. A router is configured with a router ID. When a router receives a BGP route update, it compares the router ID with the ORIGINATOR_ID attribute in the route update. If they are the same, the router drops the route update to avoid routing loops.

Views System view Predefined user roles network-admin mdc-admin Parameters router-id: Specifies a router ID in IP address format. Usage guidelines Some routing protocols use a router ID to identify a device. You can configure a global router ID, which is used by routing protocols that have no router ID configured. If no global router ID is configured, the highest loopback address, if any, is used as the router ID.
mdc-admin Parameters router-id: Specifies a router ID for BGP, in IP address format. Usage guidelines To run BGP, a router must have a router ID, which is an unsigned 32-bit integer that uniquely identifies the router in the AS. To modify a non-zero router ID for BGP, execute the router-id command in BGP view. To improve availability, specify the IP address of a loopback interface as the router ID for BGP.
Usage guidelines To run BGP, a VPN instance must have a router ID, which is an unsigned 32-bit integer that uniquely identifies the BGP VPN router in the AS. To improve availability, specify the IP address of a loopback interface as the router ID. You can specify a different router ID for each VPN instance on a device. If you execute this command in the same BGP-VPN instance view multiple times, the most recent configuration takes effect.
Usage guidelines This feature enables generating SNMP notifications for BGP as defined in RFC 4273 upon neighbor state changes. The SNMP notifications include the neighbor address, the code and subcode of the most recent error, and the current neighbor state. The generated SNMP notifications are sent to the SNMP module. The SNMP module determines how to output the notifications according to the configured output rules.
