Virtual Router Redundancy Protocol Commands

Interface Tracking
For interface tracking, VRRP is a routing event client. When a routing
interface goes up or down (or routing is disabled globally, implying all routing
interfaces are down), VRRP checks if the interface is tracked. If so, it adjusts
the priority. Interface tracking is useful for tracking interfaces that are not
configured for VRRP. Only IP interfaces are tracked.
Route Tracking
The network operator may perform this task to track the reachability of an IP
route. A tracked route is considered up when a routing table entry exists for
the route and the route is accessible. For route tracking, make VRRP a best
route client of RTO. When a tracked route is added or deleted, change the
priority. For simplicity, routes are not distinguished with the next hop
interface that has VRRP enabled. So VRRP Route Tracking can ignore route
modifications.
