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.
Figure 14 Network diagram
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] bfd echo-source-ip 1.1.1.1
[RouterS] ip prefix-list abc index 10 permit 4.4.4.4 32
[RouterS] route-policy frr permit node 10
