Configuring BFD for RIP (Single-Hop Detection in BFD Echo Packet Mode)

Network requirements
Switch A and Switch C are interconnected through a Layer 2 switch. VLAN-interface 100 of the two
switches runs RIP process 1, BFD is enabled on VLAN-interface 100 of Switch A.
Switch A is connected to Switch C through Switch B. VLAN-interface 200 on Switch A runs RIP
process 2; VLAN-interface 300 on Switch C, and VLAN-interface 200 and VLAN-interface 300 on
Switch B run RIP process 1.
