You can configure the VF tracking function when VRRP works in either the standard protocol mode 

or the load balancing mode; however, the VF tracking function is effective only when VRRP works 

in the load balancing mode. 

z 

Do not configure VF tracking on an IP address owner. 

z 

By default, the weight of a VF is 255, and its lower limit of failure is 10. 

z 

If the weight of a VF is higher than or equal to the lower limit of failure, the priority of the VF is 

always 255 and does not change with the weight value. Therefore, in case of an uplink failure, only 

when the weight of the VF owner decreases a properly specified value and becomes lower than the 

lower limit of failure, can another VF takes over the VF owner's work and becomes the AVF. 

 

Before configuring the relevant attributes of VRRP packets, you should first create a VRRP group and 

configure a virtual IP address for it. 

Follow these steps to configure VRRP packet attributes: 

Enter system view 

system-view 

— 

Enter the specified interface 
view 

interface interface-type 
interface-number 

— 

Configure the authentication 
mode and authentication key 
when the VRRP groups send 
and receive VRRP packets  

vrrp vrid virtual-router-id 
authentication-mode { md5 | 
simple } key 

Optional 

Authentication is not performed 
by default 

Configure the time interval for 
the Master in the VRRP group 
to send VRRP advertisement 

vrrp vrid virtual-router-id timer 
advertise adver-interval 

Optional 

1 second by default 

Disable TTL check on VRRP 
packets 

vrrp un-check ttl 

Optional 

Enabled by default 

You do not need to create a 
VRRP group before executing 
this command.
