Note that you can configure a tracked object for a VRRP group (using the
INTERFACE-VRID mode) before you actually create the tracked object (using a
in CONFIGURATION mode). However, no changes in the VRRP group's priority will occur until the
tracked object is defined and determined to be down.
In addition, if you configure a VRRP group on an interface that belongs to a VRF instance and later
configure object tracking on an interface for the VRRP group, the tracked interface must belong to the
VRF instance.
To track an interface, use the following command in the VRRP mode:
Task
Monitor an interface and, optionally, set a value
to be subtracted from the interface's VRRP
group priority.
(Optional) Display the configuration and UP or
DOWN state of tracked objects, including the
client (VRRP group) that is tracking an object' s
state.
(Optional) Display the configuration and UP or
DOWN state of tracked interfaces and objects
in VRRP groups, including the time since the
last change in an object's state.
(Optional) Display the configuration of tracked
objects in VRRP groups on a specified
interface.
he sum of all the costs for all tracked interfaces must be less than the configured priority of the VRRP
T
group.
