Analysis:

requires no manual intervention.
■ If it lasts long, you must ensure that these masters can receive VRRP packets
and the packets received are legitimate.
Solution:
Ping between these masters, and do the following:
■ If the ping fails, check network connectivity.
■ If the ping succeeds, check that their configurations are consistent in terms of
number of virtual IP addresses, virtual IP addresses, advertisement interval, and
authentication.
Symptom 3:
Frequent VRRP state transition.
Analysis:
The VRRP advertisement interval is set too short.
Solution:
Increase the interval to sent VRRP advertisement or introduce a preemption delay.
