Configuration procedure
1) Configure IP addresses for interfaces (omitted).
2) Configure BFD
# Configure a static route on Switch A and enable BFD on it. Implement BFD through BFD echo
packets.
<SwitchA> system-view
[SwitchA] bfd echo-source-ip 123.1.1.1
[SwitchA] interface vlan-interface 10
[SwitchA-vlan-interface10] bfd min-echo-receive-interval 500
[SwitchA-vlan-interface10] bfd detect-multiplier 7
[SwitchA-vlan-interface10] quit
[SwitchA] ip route-static 120.1.1.1 24 vlan-interface 10 10.1.1.100 bfd echo-packet
[SwitchA] ip route-static 120.1.1.1 24 vlan-interface 11 11.1.1.2 preference 65
[SwitchA] quit
3) Verify the configuration
# Display BFD session information on Switch A.
