RIP FRR configuration example
Network requirements
Switch S, Switch A, and Switch D are interconnected through RIPv2, as illustrated in Figure 14 . When Link
A fails, services will be switched to Link B immediately.

Configuration procedure
1. Configure IP addresses and subnet masks for interfaces on the switches. (Details not shown.)
2. Configure RIPv2 on the switches to make sure Switch A, Switch D, and Switch S can communicate
with each other at Layer 3 and dynamic route update can be implemented among them with RIPv2.
(Details not shown.)
3. Configure RIP FRR:
# Configure Switch S.
system-view
[SwitchS] bfd echo-source-ip 1.1.1.1
[SwitchS] ip ip-prefix abc index 10 permit 4.4.4.4 32
[SwitchS] route-policy frr permit node 10
[SwitchS-route-policy] if-match ip-prefix abc
[SwitchS-route-policy] apply fast-reroute backup-interface vlan-interface 100
backup-nexthop 12.12.12.2
[SwitchS-route-policy] quit
[SwitchS] rip 1
[SwitchS-rip-1] fast-reroute route-policy frr
[SwitchS-rip-1] quit
# Configure Switch D.
system-view
[SwitchD] bfd echo-source-ip 4.4.4.4
[SwitchD] ip ip-prefix abc index 10 permit 1.1.1.1 32
[SwitchD] route-policy frr permit node 10
[SwitchD-route-policy] if-match ip-prefix abc
[SwitchD-route-policy] apply fast-reroute backup-interface vlan-interface 101
backup-nexthop 24.24.24.2
[SwitchD-route-policy] quit
[SwitchD] rip 1
[SwitchD-rip-1] fast-reroute route-policy frr
[SwitchD-rip-1] quit45
4. Verify the configuration:
