As shown in the following figure, configure a static route to subnet 14.1.1.0/24 on Switch A and 

configure a static route to subnet 13.1.1.0/24 on Switch B. Both routes have BFD control packet mode 

enabled. When the link between Switch A and Switch B fails, BFD can detect it immediately.

1) Configure 

BFD 

# Configure Switch A. 

<SwitchA> system-view 

[SwitchA] interface vlan-interface12 

[SwitchA-vlan-interface12] ip address 12.1.1.1 24 

[SwitchA-vlan-interface12] bfd min-transmit-interval 500 

[SwitchA-vlan-interface12] bfd min-receive-interval 500 

[SwitchA-vlan-interface12] bfd detect-multiplier 9 

[SwitchA-vlan-interface12] quit 

[SwitchA] ip route-static 14.1.1.0 24 vlan-interface 12 12.1.1.2 bfd control-packet 

[SwitchA] quit 

# Configure Switch B. 

<SwitchB> system-view 

[SwitchB] interface vlan-interface12 

[SwitchB-vlan-interface12] ip address 12.1.1.2 24 

[SwitchB-vlan-interface12] bfd min-transmit-interval 500 

[SwitchB-vlan-interface12] bfd min-receive-interval 500 

[SwitchB-vlan-interface12] bfd detect-multiplier 9 

[SwitchB-vlan-interface12]] quit 

[SwitchB] ip route-static 13.1.1.0 24 vlan-interface 12 12.1.1.1 bfd control-packet 

[SwitchB] quit 

2)  Verify the configuration.
