Troubleshooting VRRP
An error prompt is displayed
Symptom
An error prompt "The virtual router detected a VRRP configuration error." is displayed during
configuration.
Analysis
This symptom is probably caused by the following reasons:
• The VRRP advertisement interval in the packet is not the same as that for the current VRRP
group (in VRRPv2 only).
• The number of virtual IP addresses in the packet is not the same as that for the current VRRP
group.
• The virtual IP address list is not the same as that for the current VRRP group.
• A device in the VRRP group receives illegitimate VRRP packets. For example, the IP address
owner receives a VRRP packet with the priority 255.
Solution
• Modify the configuration on routers in VRRP groups to ensure consistent configuration.
• Take fault location and anti-attack measures to eliminate potential threats.
Multiple masters appear in a VRRP group
Symptom
Multiple masters appear in a VRRP group.
Analysis
It is normal for a VRRP group to have multiple masters for a short time, and this situation requires no
manual intervention.
