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. Configure a static route and enable static route redistribution into RIP on Switch C. Switch A learns the static route sent by Switch C, the output interface of the route is the interface connected to the Layer 2 switch. Configure BFD so that when the link between Switch C and the Layer 2 switch 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 40
