Layer 3 Routing Commands 1944
decrease the priority of the device within the VRRPv3 group when the BFD
session goes down. Similarly, the priority is increased when the BFD session
comes up. The default decrement is 10.
The overall state of a track object is only when both the interface and BFD
session are up. The increment and decrement is performed based on the
overall state of the track object.
