Virtual Router Redundancy Protocol Commands

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.

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.

This chapter explains the following commands:
