Remarks
Configure the interface to be
tracked
vrrp vrid virtual-router-id track

Optional
No interface is being tracked by

Configure VRRP to track a
specified track entry

priority-reduced | switchover ]
Optional
Not configured by default.
NOTE:
•
The running priority of an IP address owner is always 255 and you do not need to configure it. An IP
address owner always works in preemptive mode.
•
Do not configure VRRP tracking for an interface or a track entry on an IP address owner.
•
The tracked interface can be a Layer 3 Ethernet interface, a VLAN interface, or a Layer 3 aggregate
interface.
•
If the state of a tracked interface changes from down or removed to up, the priority of the router where
the interface resides is automatically restored.
•
If the state of a track entry changes from negative or invalid to positive, the priority of the router where
the track entry is configured is automatically restored.
Configuring VF Tracking
Configuration prerequisites
Before configuring the VF tracking function, create a VRRP group and configure a virtual IP address for
it.
Configuration procedure
VRRP works in load balancing mode. Suppose that the VF is configured to monitor the track entry. When
the state of the track entry becomes negative, the weight values of all VFs on the routers decrease by a
specified value; when the state of the track entry becomes positive or invalid, the weight values of all VFs
on the routers restore their original values.
Follow these steps to configure VF tracking:
