Dell EMC SmartFabric OS10 User Guide Release 10.5.0

Object tracking

As a client, VRRP can track up to 20 interface objects plus 12 tracked interfaces supported for each VRRP group. You can assign a unique priority-cost value, from 1 to 254, to each tracked VRRP object or group interface.

If a tracked VRRP object is in a Down state, the priority cost is subtracted from the VRRP group priority. If a VRRP group router acts as owner-master, the run-time VRRP group priority remains fixed at 255. Changes in the state of a tracked object have no effect.

In VRRP object tracking, the sum of the priority costs for all tracked objects and interfaces cannot equal or exceed the priority of the VRRP group.
