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. Each VRRP group can track changes in the status of up to 12 interfaces and up to 20 additional objects, which may affect the priority of the VRRP group. If a tracked interface or object goes down, the VRRP group's priority is decreased by a default value of 10 (also known as cost). If the state of a tracked interface or object 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 must be less than 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. For a virtual group, you can track the line-protocol state or the routing status of any of the following interfaces with the interface interface parameter: • 40-Gigabit Ethernet: Enter fortygigabitethernet slot/port in the track interface command (refer to Step 1 below). • 10-Gigabit Ethernet: Enter tengigabitethernet slot/port. • Port channel: Enter port-channel number, where valid port-channel numbers are: 1 to 128. • VLAN: Enter vlan vlan-id, where valid VLAN IDs are from 1 to 4094.
