    IMPORTANT: You must create the VRRP group and assign a virtual IP address to it before you can associate it with any track entry. The vrrp vrid track command cannot take effect on an IP address owner. If you have configured the command on an IP address owner, the configuration takes effect after the router changes to be a non IP address owner.
