In a VRRP HSB Scenario, When the Active AC Is Restarted, an Active/Standby Switchover Is Triggered Normally. After the Original Active AC Is Restarted, All APs Become Faulty and Services Are Interrupted. Why?
Run the vrrp recover-delay command on the active AC. If the vrrp recover-delay command is not used, two masters may exist when the original active AC is restarted after an active/standby switchover. In this case, APs enter the Fault state.
