fast-reroute

Use fast-reroute to configure RIP FRR.

Use undo fast-reroute to disable RIP FRR.

Syntax

fast-reroute route-policy route-policy-name

undo fast-reroute

Default

RIP FRR is disabled.

Views

RIP view

Predefined user roles

network-admin

Parameters

route-policy route-policy-name: Specifies a routing policy by its name, a case sensitive string of 1 to 63 characters. If you specify this option, the command designates a backup next hop for the routes that match the routing policy.

Usage guidelines

RIP FRR is available only when the state of primary link (with Layer 3 interfaces staying up) changes from bidirectional to unidirectional or down. A unidirectional link refers to the link through which packets are forwarded only from one end to the other.

RIP FRR is only effective for RIP routes that are learned from directly connected neighbors.

Equal-cost routes do not support RIP FRR.

Examples

# Enable RIP FRR and use routing policy frr to specify a backup next hop.

<Sysname> system-view
[Sysname] ip prefix-list abc index 10 permit 100.1.1.0 24
[Sysname] route-policy frr permit node 10
[Sysname-route-policy-frr-10] if-match ip address prefix-list abc
[Sysname-route-policy-frr-10] apply fast-reroute backup-interface vlan-interface 1 backup-nexthop 193.1.1.8
[Sysname-route-policy-frr-10] quit
[Sysname] rip 100
[Sysname-rip-100] fast-reroute route-policy frr
