Hi,
The RETRY LIMIT EXCEEDED: Indicates that EIGRP did not receive the
acknowledgement from the neighbor for EIGRP reliable packets and that EIGRP
already has tried to retransmit the reliable packet 16 times without any
success.
To troubleshoot this problem, ping the neighbor interface with a small packet
(100 bytes) and then with large packets (1400 -1500 bytes)
if it does not works then check if you have High CPU Utilization on the
routers, or, you could have a Layer 1/2 Problem.
if the ping works check then the routing table for the neighbor interface IP
Address.
is the neighbor showing the correct next-hop address?? if not then you have a
Routing Problem, that means, that is possible that your neighbor next-hop IP
Address does not correspond to the actual physical connection. if the next
hop is correct then Repeat the Test from the neighbor router.
HTH

Subject: LabDate-24thFEB: Need advice -EIGRP "retry limit exceeded"
Gurus,
Was doing this IEWB lab V4 (coincidentally my friend had same issue in some
other place .), had config'd EIGRP over Ethernet between 3 routers, very
simple config, nothing happened, the Adj came up.
then after sometime, they started flapping with "retry limit exceeded",
between this time, nothing was changed, initially routers were in half-duplex
mode, i thot, it shudn't make any impact as im looking for
connectivity/routing , might not be optimum.
So my request, the possible issues that cud be there and the "Gotchas"
what we should be looking at....any inputs at this hour will be a lifesaver.
Shukla.
