Configuring BFD for RIP (single-hop echo detection)

Network requirements
As shown in
GigabitEthernet 2/1/2 of Router A runs RIP process 2. GigabitEthernet 2/1/2 on Router C and
GigabitEthernet 2/1/1 and GigabitEthernet 2/1/2 on Router B run RIP process 1.
Configure a static route destined for 100.1.1.1/24 and enable static route redistribution into RIP on
Router C so Router A can learn two routes destined for 100.1.1.1/24 through GigabitEthernet 2/1/1
and GigabitEthernet 2/1/2, respectively, and uses the one through GigabitEthernet 2/1/1.
Enable BFD for RIP on GigabitEthernet 2/1/1 of Router A. When the link over GigabitEthernet 2/1/1
fails, BFD can quickly detect the link failure and notify it to RIP so RIP deletes the neighbor
relationship and the route information learned on GigabitEthernet 2/1/1, and uses the route destined
for 100.1.1.1 24 through GigabitEthernet 2/1/2.
