Configuring RIP FRR

Network requirements

As shown in Figure 14, Router S, Router A, and Router D run RIPv2. Configure RIP FRR so that when Link

A becomes unidirectional, traffic can be switched to Link B immediately.

Configuration procedure

1. Configure IP addresses and subnet masks for interfaces on the routers. (Details not shown.)

2. Configure RIPv2 on the routers to make sure Router A, Router D, and Router S can communicate

with each other at the network layer. (Details not shown.)

3. Configure RIP FRR:

# Configure Router S.

<RouterS> system-view

[RouterS] ip prefix-list abc index 10 permit 4.4.4.4 32

[RouterS] route-policy frr permit node 10

[RouterS-route-policy-frr-10] if-match ip address prefix-list abc

[RouterS-route-policy-frr-10] apply fast-reroute backup-interface gigabitethernet

2/1/1 backup-nexthop 12.12.12.2

[RouterS-route-policy-frr-10] quit

[RouterS] rip 1

[RouterS-rip-1] fast-reroute route-policy frr

[RouterS-rip-1] quit

# Configure Router D.

<RouterD> system-view

[RouterD] ip prefix-list abc index 10 permit 1.1.1.1 32

[RouterD] route-policy frr permit node 10

[RouterD-route-policy-frr-10] if-match ip address prefix-list abc

[RouterD-route-policy-frr-10] apply fast-reroute backup-interface gigabitethernet
