1.2.6 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 IP address.
II. Configuration procedure
Follow these steps to configure VRRP packet attributes:
To do…
Use the command…

Enabled by default
Do not create a standby
group before executing
this command.
Note:
z
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.
z
Factors like excessive traffic or different timer setting on switches can cause the
Backup timer to time-out abnormally and trigger a change of the state. To solve this
problem, you can prolong the time interval to send VRRP packets and configure a
preemption delay.
