By default, no interface is tracked. When the uplink interface of a router in a VRRP group fails, usually the VRRP group cannot be aware of the uplink interface failure. If the router is the master of the VRRP group, hosts on the LAN are not able to access external networks because of the uplink failure. This problem can be solved through tracking a specified uplink interface. After you configure to monitor the uplink interface, when the uplink interface is down or removed, the priority of the master is automatically decreased by a specified value, allowing a higher priority router in the VRRP group to become the master. Before executing the command, create a VRRP group on an interface and configure the virtual IP address of the VRRP group. If you configure an interface to be tracked on a router that is the IP address owner in a VRRP group, the configuration does not take effect. If the router is not the IP address owner in the VRRP group later, the configuration takes effect. When the status of the tracked interface turns from down or removed to up, the corresponding router automatically restores its priority. Related commands: vrrp vrid track and display vrrp.

Description Use vrrp vrid virtual-ip to create a VRRP group, and configure a virtual IP address for it, or, add another virtual IP address for an existing VRRP group. Use undo vrrp vrid virtual-ip to remove an existing VRRP group or the virtual IP address of the VRRP group. By default, no VRRP group is created. The system removes a VRRP group after you delete all the virtual IP addresses in it. 109

When the uplink interface of a router in a VRRP group fails, usually the VRRP group cannot be aware of
the uplink interface failure. If the router is the master of the VRRP group, hosts on the LAN are not able
to access external networks because of the uplink failure. This problem can be solved through tracking a

is down or removed, the priority of the master is automatically decreased by a specified value

Before executing the command, create a VRRP group on an interface and configure the virtual IP address
of the VRRP group.
If you configure an interface to be tracked on a router that is the IP address owner in a VRRP group, the
configuration does not take effect. If the router is not the IP address owner in the VRRP group later, the
configuration takes effect.
When the status of the tracked interface turns from down or removed to up, the corresponding router
automatically restores its priority.
