Usage Guidelines This command ties the hot standby priority of the router to the availability of its tracked objects. Use the track interface or track ip route global configuration command to track an interface object or an IP route object. The HSRP client can register its interest in the tracking process by using the standby track command commands and take action when the object changes.

When a tracked object goes down, the priority decreases by 10. If an object is not tracked, its state changes do not affect the priority. For each object configured for hot standby, you can configure a separate list of objects to be tracked.

The optional priority argument specifies how much to decrement the hot standby priority when a tracked object goes down. When the tracked object comes back up, the priority is incremented by the same amount.

When multiple tracked objects are down, the decrements are cumulative, whether configured with priority values or not.

Use the no standby group-numbertrack command to delete all tracking configuration for a group.
