external DNS

[prashant]

Hi All,

I am new to BIND and would like to have the following setup for my LAN.

BIND is configured to resolve any request from any host in the LAN.

And the BIND server's IP address is 192.168.1.2. All host having this 
DNS entry resolve all the services.

I would also like to add my ISP DNS so that anything which cannot be 
resolved by the internal BIND DNS

is resolved by the external DNS which is 212.135.1.36.

Any one can help me with that.. where to add additional config to as to 
allow this.

Many thanks

Prashant
