Symptom 1: Frequent prompts of configuration errors on the consoleThis indicates that incorrect VRRP packets are received. It may be because of theinconsistent configuration of the switches within the backup group, or the attempt ofother devices sending out illegal VRRP packets. The first possible fault can be solvedthrough modifying the configuration. And as the second possibility is caused by themalicious attempt of some devices, non-technical measures should be resorted to.II. Symptom 2: More than one master existing within a backup groupThere are also 2 reasons. One is short time coexistence of many master switches,which is normal and needs no manual intervention. Another is the long time
