Run the display bfd session command on Router A and Router B. You can see that BFD sessions
are Up. Use the display on Router A as an example.

Step 4 Associate BFD with RRPP.
# Track the BFD session on the backuprouter. If the BFD session is Down, the priority of Router
B increases by 40.
[RouterB] interface gigabitethernet 2/0/0
[RouterB-GigabitEthernet2/0/0] vrrp vrid 10 track bfd-session 2 increased 40
[RouterB-GigabitEthernet2/0/0] quit
Run the display vrrp command on Route A or Router B. You can see that Router A is the master
and Router B is the backup. You can also see the tracked BFD session and its status on Router
B.
