Configuring BFD for RIP (bidirectional detection in BFD control
packet mode)
Network requirements
As shown in the following figure:
• Router A is connected to Router C through Router B. GigabitEthernet 4/1/2 on Router A and
GigabitEthernet 4/1/1 on Router C run RIP process 1.
• Configure a static route to Router C on Router A, and configure a static route to Router A on Router
C. Enable BFD on GigabitEthernet 4/1/2 of Router A and GigabitEthernet 4/1/1 of Router C.
• Router A is connected to Router C through Router D. GigabitEthernet 4/1/1 on Router A runs RIP
process 2; GigabitEthernet 4/1/2 on Router C, and GigabitEthernet 4/1/1 and GigabitEthernet
4/1/2 on Router D run RIP process 1.
• Enable static route redistribution into RIP on Router A and Router C so that Router A and Router C
have routes to send to each other. Router A learns the static route sent by Router C, the outbound
interface is the interface connected to Router B.
• When the link between Router B and Router C fails, BFD can quickly detect the link failure and
notify it to RIP, and the BFD session goes down. In response, RIP deletes the neighbor relationship
with Router C and the route information received from Router C. Then, Router A learns the static
route sent by Router C, and the outbound interface of the route is the interface connected to Router
D.
