The EIGRP running devices send the updates around 16 times after which we get this error.
The updates require acknowledgement from the devices it has formed adjacency with.
If the acknowledgment is not received these error messages are seen.
Although the adjacency was formed at the first place, but now there is some communication problem, like k value mismatch, or probably the MTU value, etc. Check what is the difference in the version? Are the routes or the adjacency getting refreshed now and then?

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.
