H3C S5500-EI Series Ethernet Switches
Caution:
The priority of an IP address owner is always 255 and not configurable.
Interface tracking is not configurable on an IP address owner.
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:
Enter system view
Enter the specified
interface view
Configure the
authentication mode and
authentication key when
the standby groups send
and transmit VRRP
packets
Configure the time interval
for the Master in the
standby group to send
VRRP advertisement
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.
