Summary: we recently upgraded a router and circuit at one site. Router was upgraded to a 3825 from a 3640, circuit upgraded from a 3xATM/IMA to a 15 Mbit ATM DS3. All prior connections reconnected, and are working fine, except one.
Once a minute, every minute, a get the syslog EIGRP message (truncated) on this pvc:
06-05-2008 09:29:21 Neighbor 192.168.101.122 (ATM1/0.35) is up: new adjacency
06-05-2008 09:29:21 Neighbor 192.168.101.122 (ATM1/0.35) is down: retry limit exceeded
All EIGRP timers are default settings; I have run pings without any losses; I am not getting any other messages related to the other pvc on this new router.
SH IP EIGRP NEI shows a Q CNT of 1 on this link.
I am getting quite a few input errors and giants on the other end of this circuit, which is a frame-relay btw. It also has an mtu of 1500, whereas I think the 3825 has a mtu of 4470. No other errors seen on 3825 at interface or pvc (subinterface) level.
Thanks in advance. Patrick
