Step 3 Configure the Layer 2 forwarding function on the switch.
<HUAWEI> system-view
[HUAWEI] sysname Switch
[Switch] vlan 10
[Switch-vlan10] port gigabitethernet 1/0/0
[Switch-vlan10] quit
[Switch] interface gigabitethernet 1/0/1
[Switch-GigabitEthernet1/0/1] undo shutdown
[Switch-GigabitEthernet1/0/1] port trunk allow-pass vlan 10
[Switch-GigabitEthernet1/0/1] quit
[Switch] interface gigabitethernet 1/0/2
[Switch-GigabitEthernet1/0/2] undo shutdown
[Switch-GigabitEthernet1/0/2] port trunk allow-pass vlan 10
[Switch-GigabitEthernet1/0/2] quit
Step 4 Configure sub-interfaces for dot1q VLAN tag termination.
# Configure Router A.
[RouterA] interface gigabitethernet 2/0/0.1
[RouterA-GigabitEthernet2/0/0.1] control-vid 1 dot1q-termination
[RouterA-GigabitEthernet2/0/0.1] dot1q termination vid 10
# Configure Router B.
[RouterB] interface gigabitethernet 2/0/0.1
[RouterB-GigabitEthernet2/0/0.1] control-vid 1 dot1q-termination
[RouterB-GigabitEthernet2/0/0.1] dot1q termination vid 10
Step 5 Configure a BFD session.
# Configure Router A.
[RouterA] bfd
[RouterA-bfd] quit
[RouterA] bfd atob bind peer-ip default-ip interface gigabitethernet 2/0/0.1
[RouterA-bfd-session-atob] discriminator local 1
[RouterA-bfd-session-atob] discriminator remote 2
[RouterA-bfd-session-atob] dot1q vid 10
[RouterA-bfd-session-atob] commit
[RouterA-bfd-session-atob] quit
# Configure Router B.
[RouterB] bfd
[RouterB-bfd] quit
[RouterB] bfd atob bind peer-ip default-ip interface gigabitethernet 2/0/0.1
[RouterB-bfd-session-atob] discriminator local 2
[RouterB-bfd-session-atob] discriminator remote 1
[RouterB-bfd-session-atob] dot1q vid 10
[RouterB-bfd-session-atob] commit
[RouterB-bfd-session-atob] quit
After the configuration, run the display bfd session all verbose command. You can view that
the BFD session is Up. Take the display on Router A as an example.
[RouterA] display bfd session all verbose
