[dhimancisco]

I want to configure DNS in router having two default routes...how it can be possible? after configuring I can't ping the DNS server from router....

Before configuring DNS were you able to ping the DNS server from the router? (is the problem caused by the DNS configuration or did it exist before the DNS configuration?)

It would probably help if you post the configuration of the router and post the output of show ip route from the router.
