Configure the router in the 
VRRP group to work in 
preemptive mode and 
configure preemption delay 

vrrp vrid virtual-router-id 
preempt-mode [ timer delay 
delay-value ] 

Optional 

The router in the VRRP group 
works in preemptive mode and 
the preemption delay is 0 
seconds by default. 

Configure the  interface to be 
tracked 

vrrp vrid virtual-router-id track 
interface interface-type 
interface-number [ reduced 
priority-reduced ] 

Optional 

No interface is being tracked by 
default. 

Configure VRRP to track a 
specified Track object 

vrrp vrid virtual-router-id track 
track-entry-number [ reduced 
priority-reduced | switchover ]

Optional 

Not configured by default. 

 

 

z 

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 the preemptive mode. 

z 

Do not configure VRRP tracking of an interface or an object on an IP address owner. 

z 

If the state of the interface under tracking changes from down or removed to up, the priority of the 

router corresponding to the interface is restored automatically. 

z 

If the state of a Track object changes from negative or invalid to positive, the priority of the router 

corresponding to the Track object is restored automatically. 

 

Before configuring the VF tracking function, create a VRRP group and configure a virtual IP address for 

it. 

VRRP works in the load balancing mode. Suppose that the VF is configured to monitor the Track object. 

When the state of the Track object becomes negative or invalid, the weight values of all VFs on the 

routers decrease by a specified value; when the state of the Track object becomes positive, the weight 

values of all VFs on the routers restore their original values. 

Follow these steps to configure VF tracking: 

Enter system view 

system-view 

— 

Enter the specified interface 
view 

interface interface-type 
interface-number 

— 

Configure the VF to monitor a 
specified Track object 

vrrp vrid virtual-router-id 
weight track 
track-entry-number [ reduced 
weight-reduced ] 

Required 

No Track object is specified by 
default.
