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.

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.
