Step 3 Configure basic BFD functions.
# Configure a peer BFD session on Router A.
<RouterA> system-view
[RouterA] bfd
[RouterA-bfd] quit
[RouterA] interface gigabitethernet 2/0/0
[RouterA-GigabitEthernet2/0/0] ip address 10.1.1.1 24
[RouterA-GigabitEthernet2/0/0] quit
[RouterA] bfd atob bind peer-ip 10.1.1.2 interface gigabitethernet 2/0/0
[RouterA-bfd-session-atob] discriminator local 1
[RouterA-bfd-session-atob] discriminator remote 2
[RouterA-bfd-session-atob] min-rx-interval 50
[RouterA-bfd-session-atob] min-tx-interval 50
[RouterA-bfd-session-atob] commit
[RouterA-bfd-session-atob] quit
# Configure a peer BFD session on Router B.
<RouterB> system-view
[RouterB] bfd
[RouterB-bfd] quit
[RouterB] interface gigabitethernet2/0/0
[RouterB-GigabitEthernet2/0/0] ip address 10.1.1.2 24
[RouterB-GigabitEthernet2/0/0] quit
[RouterB] bfd btoa bind peer-ip 10.1.1.1 interface gigabitethernet 2/0/0
[RouterB-bfd-session-btoa] discriminator local 2
[RouterB-bfd-session-btoa] discriminator remote 1
[RouterB-bfd-session-btoa] min-rx-interval 50
[RouterB-bfd-session-btoa] min-tx-interval 50
[RouterB-bfd-session-btoa] commit
[RouterB-bfd-session-btoa] quit
# After completing the preceding configurations, run the display bfd session command on
Router A or Router B. The peer BFD session is Up. In the following example, the display on
Router A is used.
[RouterA] display bfd session all

Step 4 Associate the VRRP backup group with the peer BFD session.
# Configure the VRRP backup group to track the peer BFD session on Router B and allow
Router B to increase its VRRP priority by 40 if the peer BFD session goes Down.
[RouterB-GigabitEthernet2/0/0] vrrp vrid 10 track bfd-session 2 increased 40
[RouterB-GigabitEthernet2/0/0] quit
After completing the preceding configurations, run the display vrrp command on Router A or
Router B. The VRRP status is Master on Router A and Backup on Router B. The command
output on Router B also shows that the VRRP backup group is tracking the peer BFD session
and the peer BFD session goes Up.
