Configuring BFD for RIP (bidirectional control detection)
Network requirements
As shown in Figure 13, GigabitEthernet 2/1/2 of Router A and GigabitEthernet 2/1/1 of Router C run
RIP process 1. GigabitEthernet 2/1/1 on 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 D run RIP process 1.
• Configure a static route destined for 100.1.1.0/24 on Router A.
• Configure a static route destined for 101.1.1.0/24 on Router C.
• Enable static route redistribution into RIP on Router A and Router C. This allows Router A to learn two
routes destined for 100.1.1.0/24 through GigabitEthernet 2/1/2 and GigabitEthernet 2/1/1. It
uses the route through GigabitEthernet 2/1/2.
• Enable BFD for RIP on GigabitEthernet 2/1/2 of Router A and GigabitEthernet 2/1/1 of Router C.
When the link over GigabitEthernet 2/1/2 fails, BFD can quickly detect the link failure and notify RIP so
RIP deletes the neighbor relationship and the route information learned on GigabitEthernet 2/1/2. It
uses the route destined for 100.1.1.0/24 through GigabitEthernet 2/1/1.
