NOTE:
•
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 preemptive mode.
• If you configure an interface to be tracked or a track entry to be monitored on a router that is the IP
address owner in a VRRP group, the configuration does not take effect. If the router is not the IP address
owner in the VRRP group later, the configuration takes effect.
• If the state of a tracked interface changes from down or removed to up, the priority of the router where
the interface resides is automatically restored.
• If the state of a track entry changes from negative or invalid to positive, the priority of the router where
the track entry is configured is automatically restored.
