Optional
The router in the VRRP group
works in preemptive mode and
the preemption delay is 0
seconds by default.
If the router in the VRRP group
works in non preemptive mode,
the preemption delay changes
to zero seconds automatically.

z
The running priority of an IP address owner is always 255 and you do not need to configure it. An IP
address owner always works in the preemptive mode.
z
Do not configure VRRP tracking of an interface or an object on an IP address owner.
z
If the state of the interface under tracking changes from down to up, the priority of the device
corresponding to the interface is restored automatically.
z
If the state of a Track object changes from negative to positive, the priority of the device
corresponding to the Track object is restored automatically.
