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:
•
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.
