Young,
Provided there are no routes explicitly configured on the
routers and the routing table reflects only connected
networks:
3600 will be able to ping the IBM router's ethernet
interface becuse 3600 e1 and IBM's ethernet interface are
in the same subnet. So both routers will have this subnet
as connected networks in their routing table.
when you are pinging from the PC(192.168.0.2/default
gateway:e0 interface of 3600), the echo request packets
will reach all the way till the IBM router's ethernet
interface but the IBM router does not have a route for
192.168.0.0 network. So this router will be unable to send
echo replies back to the PC.
HTH.
Thanks.
Murali.
