I was finishing task when in bullet 4 I noticed i need to send traffic throght SW4 to R5.
Problem is SW4 can't ping R5 interface or vise versa.
Could it be issue where F0/0 flapping and creating huge Ques with RTO of 5000 ?
Rack1R5#sh ip eigrp neighbors
IP-EIGRP neighbors for process 100
H Address Interface Hold Uptime SRTT RTO Q Seq
(sec) (ms) Cnt Num
0 183.1.105.10 Fa0/0 12 00:00:21 1 5000 2 0
It's flapping every few minutes.
*Mar 1 01:35:09.947: %DUAL-5-NBRCHANGE: IP-EIGRP(0) 100: Neighbor 183.1.105.10 (FastEthernet0/0) is down: retry limit exceeded
*Mar 1 01:35:10.815: %DUAL-5-NBRCHANGE: IP-EIGRP(0) 100: Neighbor 183.1.105.10 (FastEthernet0/0) is up: new adjacency
Which debugs can i run to troubleshoot this issue, I think eigrp configuration is correct, could it be IOS issue ?
SW4 is 3550 in my case with 12.1(22)EA10
