Configuration procedure:
Switch A:
Switch#config
Switch(config)#bfd mode active
Switch(config)#interface vlan 100
Switch(config-if-vlan100)#ip address 10.1.1.1 255.255.255.0
Switch(config)#interface vlan 200
Switch(config-if-vlan200)#ip address 20.1.1.1 255.255.255.0
Switch(config)#router rip
Switch (config-router)#network vlan 100
Switch (config-router)#network vlan 200
Switch(config)#interface vlan 100
Switch(config-if-vlan100) #rip bfd enable
Switch B:
Switch#config
Switch(config)#bfd mode passive
Switch(config)#interface vlan 100
Switch(config-if-vlan100)#ip address 10.1.1.2 255.255.255.0
Switch(config)#interface vlan 300
Switch(config-if-vlan300)#ip address 30.1.1.1 255.255.255.0
Switch(config)#router rip
Switch (config-router)#network vlan 100
Switch (config-router)#network vlan 300
Switch(config)#interface vlan 100
Switch(config-if-vlan100) #rip bfd enable
When the link between Switch A and Switch B is failing, BFD can detect it immediately and
notifies RIP to delete the learnt route.
42.3.3 Example for Linkage of BFD and VRRP
Example:
When the master is failing, the backup cannot become the master until the configured
timeout timer expires. The timeout is generally three to four seconds and therefore the
