You can use the ip vrrp track command (in conjunction with the track command) to track an object by its virtual router ID (VRID). When
the state of the object changes from an up state to a down state,
the priority of the vrid is decremented. When the object changes back
to an up state the priority is restored. You can specify a priority
value in the range 1–255 to be used for modifying the priority;
the default value is 10.
For information about the track command
see Managing the System in JUNOSe System Basics Configuration Guide.
Use to dynamically change the priority of a virtual router
ID (VRID) in response to a change in the state of a specified object.
You can specify the value by which the priority changes in the range
1–255 or use the default value (10). Multiple VRIDs can track
the same object and a single VRID can track multiple objects. The
object priority is restored when the state of the object returns to
an up state.
host1(config-if)#ip vrrp 25 track abc
host1(config-if)#ip vrrp track xyz decrement
Use the no version to disable
any tracking for the object.
