I have 3 pc's connected to the ethernet interfaces of 3 2500 series routers. The 3 routers are running rip on a 10.0.0.0 network across all the interfaces. The pc's are right,middle and left and are connected to the routers bottom, middle and top respectively. My problem is this. The right pc will not ping beyond the aui interface of the bottom router and ony the right pc's local router (bottom) can ping the rightpc, yet I have full connectivity between all other routers and pc's. The 3 host pc's have identical ip configs (different addresses of course).
ip address 10.10.90.7 mask 255.255.255.0 default gateway 10.10.90.1
aui ip 10.10.90.1 mask 255.255.255.0
no ip directed braoadcast
I have a sniffer running on the bottom pc, if I ping the bottom pc from say left pc I can see the echo request come in. The right pc simply does not echo reply. Yet if I ping the right pc from its local router bottom I can see the echo request and reply no problem.
I can ping the left and middle pc' and the top and middle routers from the bottom router and vice versa. Usually the logic of such a failure would point one towards the fault but this is ones got me. Any pointers would would earn points
