Virtual Router Redundancy Protocol Commands

User Guidelines
This command has no user guidelines.
Example
The following configures VLAN 15 virtual router to learn the advertisement
interval used by the master virtual router.
console(config-if-vlan15)#vrrp 5 timers learn
vrrp track interface
Use the
vrrp track interface
command in Interface Configuration mode to
alter the priority of the VRRP router based on the availability of its interfaces.
It is useful for tracking interfaces that are not configured for VRRP. Only
routing interfaces may be tracked. A tracked interface is up if routing on that
interface is up. Otherwise, the tracked interface is down.
When the tracked interface is down, or the interface has been removed from
the router, the priority of the VRRP router will be decremented by the value
specified in the priority argument. When the interface is up for the IP
protocol, the priority will be incremented by the priority value.
A VRRP configured interface can track more than one interface. When a
tracked interface goes down, then the priority of the router will be decreased
by 10 (default priority decrement) for each downed interface. The default
priority decrement is changed using the priority argument. The default
priority of the virtual router is 100, and the default decrement priority is 10.
By default, no interfaces are tracked. If you specify, just the interface to be
tracked without giving the priority, which is optional, then the default priority
will be set.
Use the
no form of this command to remove the interface from the tracked
list or to restore the priority decrement to its default. When removing an
interface from the tracked list, the priority is incremented by the decrement
value if that interface is down.
