Caution:
z
The priority of an IP address owner is always 255 and not configurable.
z
Interface tracking is not configurable on an IP address owner.
z
The priority of a device is reset if the state of the interface under tracking changes
from down to up.
1.3.6 Configuring VRRP Packet Attributes
I. Configuration prerequisites
Before configuring the relevant attributes of VRRP packets, you should first create the
standby group and configure the virtual IPv6 address.
II. Configuration procedure
Follow these steps to configure VRRP packet attributes:
To do…
Use the command…

You may configure different authentication modes and authentication keys for the
standby groups on an interface. However, the members of the same standby group
must use the same authentication mode and authentication key.
Factors like excessive traffic or different timer setting on switches can cause the
Backup timer to time-out abnormally and change the state. To solve this problem, you
can prolong the time interval to send VRRP packets and configure a delay for
preemption.
