21.2 Configuring TRACK
21.2.1 Understanding track
Before the introduction of track feature, the VRRP had a simple tracking
mechanism that allowed you to track the interface link state only. If the link state
of the interface went down, the VRRP priority of the router was reduced, allowing
another VRRP router with a higher priority to become active. The Track feature
separates the tracking mechanism from VRRP and creates a separate standalone
tracking process that can be used by other processes in future. This feature allows
tracking of other objects in addition to the interface link state. VRRP can now
register its interest in tracking objects and then be notified when the tracked object
changes state. TRACK is a separate standalone tracking process that can be used by
other processes as well as VRRP. This feature allows tracking of other objects in
addition to the interface link state.
