Configuring BFD for VRRP

To configure BFD for VRRP, you need to configure a BFD track entry and then bind the track entry to a
VRRP group.
Track starts and stops the BFD session. Upon detecting a neighbor failure, BFD notifies Track of the
failure. Then, Track notifies it to VRRP for quick VRRP master/backup switchover.
Before associating a VRRP group with a track entry, you need to create the VRRP group on the
interface and assign a virtual IP address to it.
Follow these steps to configure BFD for VRRP:
To do...
Enter system view
Configure the source
address of echo packets

entry
Enter interface view
Bind a VRRP group with
the Track entry
Use the command...
