Configuration procedure
Follow these steps to configure VRRP packet attributes:
n
■ 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.
