First Hop Redundancy Protocol: Object Tracking

Object tracking can check on specific objects in the network, and work with First Hop Redundancy Protocols to take various actions depending on that objects status.

For example, the reachability of route of can be tracked with the following command in global configuration mode:

track 10 ip route reachability

The status of that object tracking can be checked with the command show track.

Use With Hot Standby Router Protocol and Virtual Router Redundancy Protocol

HSRP can utilise tracking objects to increase or decrease the priority on the router. An example of tracking object 10 in interface configuration mode would be:

standby 20 track 10 decrement 20

If the tracking object 10 returns a negative result, the priority of the HSRP will decrease by 20
