Configuring BFD for RIP (bidirectional control detection)
Network requirements
As shown in Figure 13, Ethernet 1/2 of Router A and Ethernet 1/1 of Router C run RIP process 1. Ethernet
1/1 on Router A runs RIP process 2. Ethernet 1/2 on Router C, and Ethernet 1/1 and Ethernet 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 o n R o u t e r C , a n d e n a b l e s t a t i c r o u t e r e distribution into RIP on Router A and Router C so
Router A can learn two routes destined for 100.1.1.0/24 through Ethernet 1/2 and Ethernet 1/1,
respectively, and uses the one through Ethernet 1/2.
Enable BFD for RIP on Ethernet 1/2 of Router A and Ethernet 1/1 of Router C. When the link over
Ethernet 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 Ethernet 1/2, and uses the route destined for
100.1.1.0/24 through Ethernet 1/1.
