Gurus,
Would appreciate some light;
R4----Fa0/4(SW2)====IP- Port-Channel===(SW3)Fa0/24----BB3.
R4/BB3 in the same IP Subnet and ports in same Vlan #4, with the port-channel between SW2&SW3 having its own IP subnet , with nothing else much configured R4 cant ping BB3 and vice versa, and if I remove the port-channel and keep normal trunks, they all Ping!! :-(
with restrictions, what all directions do i need to run?

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.
