ip vrrp track interface
This command alters the priority of the VRRP router based on the availability of its interfaces. This
command is useful for tracking interfaces that are not configured for VRRP. Only IP interfaces are
tracked. A tracked interface is up if the IP 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 decrement argument. W hen the
interface is up for IP protocol, the priority will be incremented by the decrement value.
A VRRP configured interface can track more than one interface. W hen a tracked interface goes down,
then the priority of the router will be decreased by 10 (the default priority decrement) for each downed
interface. The default priority decrement is changed using the decrement 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 optional priority, then the
default priority will be set. The default priority decrement is 10.
Syntax
ip vrrp <1-255> track interface {<slot/port> | vlan <vlan-id>} [decrement <1-254>]
no ip vrrp <1-255> track interface {<slot/port> | vlan <vlan-id>} [decrement]
<1-255> -
The range of virtual router ID is 1 to 255.
< 1-254 > -
The range of decrement is 1 to 254.
<vlan-id> -
VLAN ID. The range of VLAN ID is 1 to 4093.
<no> -
This command removes the interface from the tracked list or to restore the priority
decrement to its default.
