Configuring VRRP Interface State Tracking

Interface state tracking changes the priority of the virtual router based on the state of another interface
in the device. When the tracked interface goes down or the IP address is removed, Cisco NX-OS assigns
the tracking priority value to the virtual router. When the tracked interface comes up and an IP address
is configured on this interface, Cisco NX-OS restores the configured priority to the virtual router (see
the"Configuring VRRP Priority" section on page
Note For interface state tracking to function, you must enable preemption on the interface.
