VLAN-interface100 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 onSwitch C. Enable BFD on VLAN-interface 100 of Switch A and VLAN-interface 200 ofSwitch C.• Switch A is connected to Switch C through Switch D. VLAN-interface 300 on Switch A runsRIP process 2 and VLAN-interface 400 on Switch C. 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 Switch A and SwitchC have routes to send to each other. Switch A learns the static route sent by Switch C, theoutbound interface is the interface connected to Switch B.• When the link between Switch B and Switch C fails, BFD can quickly detect the link failureand notify it to RIP, and the BFD session goes down. In response, RIP deletes the neighborrelationship with Switch C and the route information received from Switch C. Then, Switch Alearns the static route sent by Switch C, with the outbound interface of the route being theinterface connected to Switch D.
