Hi all I am facing problem in pinging. I am attaching the running configuration of the two routers. From the router central i have defined a default route to my backbone. i can access the internet through this. I have defined the ethernet interface in the same network as backbone network. i am able to ping to the external network. The second router remote, i have connected through adsl to central.i am able to reach the last point in the router central, that is, the ethernet interface in central. But i can not ping to the external network. I can not ping to the default gateway also. i have defined a default route through the interface atm0. when i give debug ip packet, i am able to see the icmp request from the router remote. but sometimes i receive the icmp type 8 and code 0 output from the router central. please could some body help me out in this.
Thanks and regards Deepak Remote router Building configuration...
