The output shows that Switch A communicates with Switch C through VLAN-interface 100. Then the link
over VLAN-interface 100 fails.

Configuring RIP FRR
Network requirements
As shown in Figure 12, Switch S, Switch A, and Switch D run RIPv2. Configure RIP FRR so that when Link
A becomes unidirectional, services can 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. (Details not shown.)
3. Configure RIP FRR:
