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. Commands in this Chapter This chapter explains the following commands: Virtual Router Redundancy Protocol Commands ip vrrp vrrp accept-mode vrrp authentication vrrp description vrrp ip vrrp mode vrrp preempt vrrp priority vrrp timers advertise vrrp timers learn vrrp track interface vrrp track ip route show vrrp show vrrp interface show vrrp interface brief show vrrp interface stats Pingable VRRP Commands ip vrrp accept-mode show ip vrrp interface Virtual Router Redundancy Protocol Commands 1381
