Each VRRP group can track up to 12 interfaces, which may affect the priority of the VRRP group. If the tracked interface goes down, the VRRP group's priority is decreased by a default value of 10 (also known as cost). If the tracked interface's state goes up, the VRRP group's priority is increased by 10. The lowered priority of the VRRP group may trigger an election. As the Master/Backup VRRP routers are selected based on the VRRP group's priority, tracking features ensure that the best VRRP router is the Master for that group. The sum of all the costs of all the tracked interfaces should not exceed the configured priority on the VRRP group. If the VRRP group is configured as Owner router (priority 255), tracking for that group is disabled, irrespective of the state of the tracked interfaces. The priority of the owner group always remains at 255. To track an interface, use the following command in the VRRP mode: Task Command Syntax Monitor an interface and, optionally, set a value to be subtracted from the interface's VRRP group priority. track interface [priority-cost cost]] Cost Range: 1-254 Default: 10 Command Mode INTERFACE-VRID The sum of all the costs for all tracked interfaces must be less than or equal to the configured priority of the VRRP group. 960 | Virtual Router Redundancy Protocol (VRRP)
