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… Remarks
Enter system view

Enter the specified interface

—
Configure the authentication
mode and authentication key
when the standby groups send
and transmit VRRP packets
vrrp ipv6 vrid

Optional

not performed by
default
Configure the time interval for
the Master in the standby
group to send VRRP
advertisement
vrrp ipv6 vrid
virtual-router-id timer
advertise adver-interval
Optional
100 centiseconds
by default
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.
