Step 5 Configure the mVRRP backup group to track each link BFD session to allow BFD sampling to
help rapidly trigger a master/backup VRRP switchover.

# After completing the preceding configurations, run the display vrrp interface command on
each NPE. The allowable maximum number of tracked link BFD sessions in the Down state is
2; the mVRRP backup group has been bound to a peer BFD session and four link BFD sessions;
the status of each BFD session is UP.

Total UP/DOWN Session Number : 5/0
NOTE
The configuration is performed only for the mVRRP backup group on GE 1/0/1.1 of each NPE since service
VRRP backup groups have been bound to the mVRRP backup group.
