When the weight of a VF owner is higher than or equal to the lower limit of failure, its priority is
always 255 and does not change with the weight. To guarantee that an LVF can take over the VF
owner as the AVF when the upstream link of the VF owner fails, the reduced weight for the VF owner
must be higher than 245 so the weight of the VF owner can drop below the lower limit of failure.
Configuration procedure
To configure VF tracking:
Step
1.
Enter system view.
2.
Enter interface view.
3.
Configure the VFs in a VRRP
group to monitor a track entry
and configure the reduced
weight.

Configuring the IPv6 VRRP advertisement interval

This section describes how to configure the IPv6 VRRP advertisement interval.
Configuration guidelines
The routers in an IPv6 VRRP group can have different intervals for sending VRRP advertisements. The
master in the VRRP group sends VRRP advertisements at the specified interval and carries the
interval attribute in the advertisements. After a backup receives the advertisement, it records the
interval in the advertisement. If the backup does not receive a new VRRP advertisement from the
master when the timer (3 x recorded interval + Skew_Time) expires, it regards the master as failed
and takes over as the new master.
A high volume of network traffic might cause a backup to fail to receive VRRP advertisements from
the master within the specified time, resulting in an unexpected master switchover. To solve this
problem, configure a larger interval.
Configuration procedure
To configure the IPv6 VRRP advertisement interval:
Step
1.
Enter system view.
2.
Enter interface view.
3.
Configure the IPv6 VRRP
advertisement interval.
