Configuring BFD Control Packet Mode for Static Routing
Network requirements
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.

Configuration procedure
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.
