Router log error: %PIM-5-NBRCHG:

Unanswered Question
Apr 20th, 2009

I have a Cisco 7206 that has EIGRP configued as well as Multicast. Every once in a while I see this error in the log:

Apr 20 07:06:16.415 EDT: %PIM-5-NBRCHG: neighbor 10.0.0.1 DOWN on interface GigabitEthernet0/1 non DR

Apr 20 07:06:29.843 EDT: %PIM-5-NBRCHG: neighbor 10.0.0.1 UP on interface GigabitEthernet0/1


The network is a stub network and EIGRP really isn't needed so I added static routes but left EIGRP routing enabled.

Multicast isn't needed on this router either. The routers peer doesn't get this message.


I'm thinking this message is due to multicast but not sure exactly why.


I don't see any performance / application problems because of this and I see on Cisco that "No Action is required" for this error but I'd really like to know what might be causing it.


Any help would be greatly appreciated

It means that it has lost connection to it's PIM (multicast) neighbor.


Normally because connection has been lost with the other side of G0/1.

First off, thanks for for the reply.

I don't see the physical interface going down though.

Shouldn't I see this error in the logs of both routers for the g0/1 link?


Also, is it fair to say this is a multicast error and not a routing error?
