Hi All,
we have below connectivity
WAN CE ---> SW (3750) ---> ISP MUX --> ISP Router, on CE router side we have created sub interface on which EIGRP is running with Service provider.It is flapping daily .ISP confirmed ,as they dont have any issue.We are facing this issue for more than 3 Sites .
Oct 25 17:27:16.112: %DUAL-5-NBRCHANGE: EIGRP-IPv4 222: Neighbor X.X.X.X (GigabitEthernet0/0/3.500) is down: Interface PEER-TERMINATION received

The error message very clearly indicates that there is some problem on the neighbor side of the connection. The error message says:"Interface PEER-TERMINATION received". The peer termination says that the neighbor has decided for some reason to tear down the neighbor relationship. I suggest that you talk to them again, and point out this error message.
They may not see any interface go down and that might be the basis for them to say that there is no problem. But the error message does indicate that there is something on their end. It may be something like packet loss. If there is packet loss and you lose 3 consecutive hello messages then EIGRP will treat that as an error and will tear down the neighbor relationship. I wonder if something like that is going on.

Please verify the Bandwidth Utilization also, since the protocol used is EIGRP i would suggest to check even the bandwidth part also.

Hi,
In continuation with Rick and Hemakumar's suggestion, I would also suggest to checkout the following points:
1. Cabling at each point in between.
2. Check at your switch whether interface is going down or whether it is accumualting errors.
3. Debugs can give you better insight, why you are receiving peer termination.
