The output shows that the neighbor and route information on Switch A and Switch B keep unchanged
during the active/standby switchover on Switch S. The traffic from Switch A to Switch B has not been
impacted.
Configuring BFD for RIP (single-hop echo detection for a
directly connected neighbor)
Network requirements
As shown in
VLAN-interface 200 of Switch A runs RIP process 2. VLAN-interface 300 of Switch C and
VLAN-interface 200 and VLAN-interface 300 of Switch B run RIP process 1.
•
Configure a static route destined for 100.1.1.1/24 and enable static route redistribution into RIP
on Switch C. This allows Switch A to learn two routes destined for 100.1.1.1/24 through
VLAN-interface 100 and VLAN-interface 200 respectively, and uses the one through
VLAN-interface 100.
