IGRP problems ??

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

2513 router all stringed togather 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 192.168.0.100: 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: 192.168.0.0 Routing Information Sources: Gateway Distance Last Update 192.168.4.4 100 00:01:16 Distance: (default is 100)

Just to give a fighting chance of properly diagnosing the problem you'll have to provide a lot more info. Which router is the desktop using as its GW? Include the output for sh ip route, sh ip protocol, and sh startup-config for all the routers otherwise we'd just be guessing. Does the network look like this:

router1 router2 router3 router4

If your using bridging you don't need to be running IGRP.

If you're bridging between the interfaces on the router then any routing protocol is useless because the routing is acting like a switch not a router.

You'ld have to explain why your desktop is acting as a router.
