Configuring BFD for RIP (single-hop echo detection for a
directly connected RIP neighbor)
Network requirements
As shown in Figure 9, Ethernet 1/1 of Router A and Router C runs RIP process 1. Ethernet 1/2 of Router
A runs RIP process 2. Ethernet 1/2 on Router C and Ethernet 1/1 and Ethernet 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 Ethernet 1/1 and Ethernet 1/2,
respectively, and uses the one through Ethernet 1/1.
Enable BFD for RIP on Ethernet 1/1 of Router A. When the link over Ethernet 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 Ethernet 1/1, and uses the route destined for 100.1.1.1 24 through Ethernet 1/2.

Configuration procedure
1. Configure IP addresses for interfaces. (Details not shown.)
2. Configure basic RIP and enable BFD on the interfaces:
