6.4 Configuring VRRP to Track the Status of an Interface

By configuring a VRRP backup group to track the interface status, you can implement the backup
function when the interface fails.
6.4.1 Establishing the Configuration Task
Before configuring a VRRP backup group to track the interface status, familiarize yourself with
the applicable environment and complete the pre-configuration task of configuring a VRRP
backup group.
Applicable Environment
VRRP tracking interface status provides the backup function when the interface where the VRRP
backup group resides is faulty or when another interface on the switch is faulty.
The method of tracking the status of the interface are as follows:
1.
2.
Pre-configuration Tasks
Before configuring VRRP to track the status of an interface, complete the following tasks:

When the tracked interface is Down, the priority of the switch in the backup group reduces
by a certain value automatically to be lower than that of other switchs in the group.
The switch with the highest priority becomes the master switch and thus the master/backup
switchover of the VRRP backup group is complete.
