Verify VRRP tracking

Updated: February 6, 2026

Overview

Provides details about verifying the operational status of VRRP groups and their associated track objects. These commands help you confirm that the system is actively monitoring leaked routes and responding correctly to changes in their reachability status.

Verifying VRRP tracking provides insight into the operational status of VRRP groups and their associated track objects. This information is crucial for confirming that VRRP is actively monitoring the reachability of leaked routes.

VRRP group status details

The following is a sample output from the show vrrp details command that shows the status of the configured VRRP groups on a Cisco IOS XE Catalyst SD-WAN device.
