In IPv6network, you need to manually configure the default gateway for VRRP standbygroup to share load.Troubleshooting VRRP Symptom 1:The console screen displays error prompts frequently.Analysis:This error is probably due to the inconsistent configuration of the other switch inthe standby group, or that a device is attempting to send illegitimate VRRPpackets.Solution:■ In the first case, modify the configuration.■ In the latter case, you have to resort to non-technical measures.Symptom 2:Multiple masters are present in the same standby group.Analysis:■ If presence of multiple masters only lasts a short period, this is normal andrequires no manual intervention.■ If it lasts long, you must ensure that these masters can receive VRRP packetsand the packets received are legitimate.Solution:Ping between these masters, and do the following:
