Configuring BFD for RIP (Bidirectional Detection in BFD Control Packet Mode)

Network requirements
Switch A is connected to Switch C through Switch B. VLAN-interface 100 on Switch A,
VLAN-interface 200 on Switch C, and VLAN-interface 200 and VLAN-interface 100 on Switch B run
RIP process 1.
Configure a static route to Switch C on Switch A, and configure a static route to Switch A on Switch
C. Enable BFD on VLAN-interface 100 of Switch A and VLAN-interface 200 of Switch C.
Switch A is connected to Switch C through Switch D. VLAN-interface 300 on Switch A runs RIP
process 2; VLAN-interface 400 on Switch C, and VLAN-interface 300 and VLAN-interface 400 on
Switch D run RIP process 1.
Enable static route redistribution into RIP on Switch A and Switch C so that Switch A and Switch C
have routes to send to each other. Switch A learns the static route sent by Switch C, the outbound
interface is the interface connected to Switch B.
When the link between Switch B and Switch 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 Switch C and the route information received from Switch C. Then, Switch A learns the static
route sent by Switch C, the outbound interface of the route is the interface connected to Switch D.
