VRRP IP Tracking Feature

For setup, refer to Figure VRRP- Topology 3.

VRRP enables a group of devices to form a single virtual device (aka VRRP group). The VRRP object tracking describes how to track an IP object using a VRRPv3 group. For individual objects, the tracking process allows tracking of a state of an interface line protocol, state of an IP route, or the reachability of a route.

Each VRRP group can track multiple objects that may affect the priority of the VRRP device. VRRP is notified of any change to a specified object to be tracked. VRRP increments (or decrements) the priority of the virtual device based on the state of the object being tracked.

Note: The VRRP IP Tracking Feature only works for VRRP Version 3.

This section describes the configuration commands for VRRP IP tracking feature.

Query is a set of ping packets that is sent out of a switch. The switchover of Master to Backup and vice versa case depends on the number of query success and failure. Ideally if it is set minimum, a quick switch over time can be achieved.
