Configuration procedure
1. Configure IP addresses for the interfaces. (Details not shown)
2. Configure BFD:
# Configure static routes on Router A and enable BFD control packet mode for the static route
through the Layer 2 switch.
<RouterA> system-view
[RouterA] interface GigabitEthernet 3/1/1
[RouterA-GigabitEthernet3/1/1] bfd min-transmit-interval 500
[RouterA-GigabitEthernet3/1/1] bfd min-receive-interval 500
[RouterA-GigabitEthernet3/1/1] bfd detect-multiplier 9
[RouterA-GigabitEthernet3/1/1] quit
[RouterA] ip route-static 120.1.1.0 24 GigabitEthernet 3/1/1 12.1.1.2 bfd
control-packet
[RouterA] ip route-static 120.1.1.0 24 GigabitEthernet 3/1/2 10.1.1.100 preference
65
[RouterA] quit
# Configure static routes on Router B and enable BFD control packet mode for the static route
through the Layer 2 switch.
<RouterB> system-view
[RouterB] interface GigabitEthernet 3/1/1
[RouterB-GigabitEthernet3/1/1] bfd min-transmit-interval 500
[RouterB-GigabitEthernet3/1/1] bfd min-receive-interval 500
[RouterB-GigabitEthernet3/1/1] bfd detect-multiplier 9
[RouterB-GigabitEthernet3/1/1] quit
[RouterB] ip route-static 121.1.1.0 24 GigabitEthernet 3/1/1 12.1.1.1 bfd
control-packet
[RouterB] ip route-static 121.1.1.0 24 GigabitEthernet 3/1/2 13.1.1.2 preference 65
[RouterB] quit
3. Verify the configuration:
The following operations are performed on Router A. The operations on Router B are similar.
