Configuring Bfd For Rip (Bidirectional Control Detection) - HP MSR Series Configuration Manual

Configuring BFD for RIP (bidirectional control detection)

Network requirements
As shown in
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 on Router C, and enable static route redistribution 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 it to RIP so RIP deletes the neighbor
relationship and the route information learned on Ethernet 1/2, and uses the route destined for
00.1.1.0/24 through Ethernet 1/1.

Configuration procedure
1. Configure IP addresses for interfaces. (Details not shown.)
2. Configure basic RIP basic and enable static route redistribution into RIP so Router A and Router C
have routes to send to each other:
# Configure Router A.
