Configuring RIP FRR
Network requirements
Router S, Router A, and Router D are interconnected through RIPv2, as illustrated in
. Configure
RIP FRR so that when Link A between Router S and Router D fails, traffic can be switched to Link B
immediately.

Configuration procedure
1.
Configure IP addresses for the interfaces on each router and configure RIPv2:
Follow
to configure the IP address and subnet mask of each interface on the routers.
(Details not shown)
Configure RIPv2 on the routers, making sure that Router A, Router D, and Router S can
communicate with each other at Layer 3. (Details not shown)
2.
Configure RIP FRR:
# Configure Router S.

[RouterS] bfd echo-source-ip 1.1.1.1
[RouterS] ip ip-prefix abc index 10 permit 4.4.4.4 32

[RouterS-route-policy] if-match ip-prefix abc
[RouterS-route-policy] apply fast-reroute backup-interface GigabitEthernet 3/1/1
backup-nexthop 12.12.12.2
[RouterS-route-policy] quit
[RouterS] rip 1
[RouterS-rip-1] fast-reroute route-policy frr
[RouterS-rip-1] quit
# Configure Router D.
<RouterD> system-view
[RouterD] bfd echo-source-ip 4.4.4.4
[RouterD] ip ip-prefix abc index 10 permit 1.1.1.1 32
[RouterD] route-policy frr permit node 10
