Troubleshooting VRRP
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.
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 checks:
•
If the ping fails, check network connectivity.
