DUAL-5-NBRCHANGE: EIGRP-IPv4 100: Neighbor (Vlan202) is down: retry limit exceeded

[Tracey Campbell]

Hi,

Need some help stopping these EIGRP sys logs.

Any ideas?

If all you are trying to do is stop the actual syslog messages, rather than fix the cause of them, then look into the logging discriminator command.

This question has been asked a few times on CSC so I will point you to a thread which may help.

I would like to resolve the issue.

In that case you really would need to supply some more information. 

Topology to begin with and relevant parts of the config of the devices involved. Has this worked up until now?

Is this physical devices or GNS3?

Grant has asked some good questions and answers to them may help us identify the problem and how to solve it. It would be helpful to know if this in an intermittent issue (neighbor frequently stays up for a while and then fails) or is it that the neighbor comes up, then fails, then comes up, then fails, over and over. 

The message indicates that you are having problems maintaining the neighbor relationship with the neighbor in vlan 202. It looks like you received an EIGRP hello from that neighbor and built a neighbor relationship. You have sent EIGRP messages to that neighbor and it did not respond. You retried the messages and it did not respond. So you drop the neighbor relationship. It might be helpful to look in the logs of that device and see if it is logging errors about EIGRP, or errors about the interface used to connect to your device. It might also be helpful to check for any connectivity problems between these interfaces.
