Configuring RIP FRR
Network requirements
Router S, Router A, and Router D are interconnected through RIPv2, as illustrated in Figure 14 . Configure
RIP FRR so that when Link A between Router S and Router D fails, traffic can be switched to Link B
immediately.
Figure 14 Network diagram
Configuration procedure
1. Configure IP addresses for the interfaces on each router and configure RIPv2:
Follow
Figure 14 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] ip ip-prefix abc index 10 permit 4.4.4.4 32

# Configure Router D.
