IGRP problems ??

I have IGRP problems ?? I have three Cisco Catalyst 3200/2503 and one

2513 router all stringed together as in 1,2,3 and 4. I am using IGRP protocol and ios v11.2 and v12.2 on each. When ever I log into router number 4's console I can ping throughout the network. From my desktop I can only ping to the 3rd router. When I ping interfaces on the 4th router from my desktop I receive an error message "Reply from Destination host unreachable". From my desktop I can ping the directly connected interface(s1) but not the other sides of the router(e0, tokenring0).

cis2513>sh ip protocol Routing Protocol is "igrp 10" Sending updates every 90 seconds, next due in 48 seconds Invalid after 270 seconds, hold down 280, flushed after 630 Outgoing update filter list for all interfaces is not set Incoming update filter list for all interfaces is not set Default networks flagged in outgoing updates Default networks accepted from incoming updates IGRP metric weight K1=1, K2=0, K3=1, K4=0, K5=0 IGRP maximum hopcount 100 IGRP maximum metric variance 1 Redistributing: igrp 10 Routing for Networks: Routing Information Sources: Gateway Distance Last Update 100 00:01:16 Distance: (default is 100)

"Destination unreachable" sounds like an acl problem..

If it were just a simple connectivity issue you would get a request "timed out" message
