Troubleshooting VRRP

Symptom 1:

The screen frequently displays error prompts.
Analysis:
This error is probably caused by:

•

Inconsistent configuration of the devices in the VRRP group.

•

A device is attempting to send illegitimate VRRP packets.

Solution:

•

In the first case, modify the configuration.

•

In the latter case, resort to non-technical measures.

Symptom 2:

Multiple masters are present in the same VRRP group.
Analysis:

•

Multiple masters coexist for a short period: This is normal and requires no manual intervention.

•

Multiple masters coexist for a long period: This is because devices in the VRRP group cannot receive

VRRP packets, or the received VRRP packets are illegal.

Solution:
Ping between these masters, and do the following:

•

If the ping fails, check network connectivity.

•

If the ping succeeds, check that their configurations are consistent in terms of number of virtual IP
addresses, virtual IP addresses, advertisement interval, and authentication.

Symptom 3:

Frequent VRRP state transition.
Analysis:
The VRRP advertisement interval is set too short.
Solution:
Increase the interval to sent VRRP advertisement or introduce a preemption delay.
