With FRR, a routing protocol can designate a backup next hop by using the referenced route

policy when a network failure is detected, and packets are directed to the backup next hop for

forwarding, thus to reduce traffic recovery time greatly.

This command allows you to specify a backup next hop in a route policy for routes matching

specified criteria.

Examples

# Configure node 10 of route policy

policy1

to specify backup outbound interface

VLAN-interface 1 and backup next hop 193.1.1.8 for packets destined to 100.1.1.0/24.

<Sysname> system-view

[Sysname] ip ip-prefix abc index 10 permit 100.1.1.0 24

[Sysname] route-policy policy1 permit node 10

[Sysname-route-policy] if-match ip-prefix abc

[Sysname-route-policy] apply fast-reroute backup-interface vlan-interface 1

Parameters

ip-address

: IP address of the next hop.

Description

Use the

apply ip-address next-hop

command to set a next hop for IPv4 routing information.

Use the

undo apply ip-address next-hop

command to remove the clause configuration.

No next hop is set for IPv4 routing information by default.

This command cannot set a next hop for redistributed routes.
