Hi Srini,

Please change the following command in your configuration -

ip route 0.0.0.0 0.0.0.0 FastEthernet4/0

Instead of pointing the route to fa4/0 point it to next hop IP address.

This statement must be causing ARP request to be generated on the ethernet for every destination the router finds through the default route because the router considers all of these destinations as directly connected to FA0.

Once you make the change keep the router under observation and see if its working properly.
