bind 9.1.2 selective forward

Hi,
  I have three servers:
server1 serves acme.com domain;
server2 serves eng.acme.com domain;
server3 serves corp.acme.com domain;

Both server 2 and server 3 use server1 as its
name server , eg. in /etc/resolv.conf.

I want to be able to lookup servers in
eng.acme.com from server3 (corp.acme.com).

Is this possisble on bind 9.1.2?

I try this in server1 /etc/named.conf and it does not work.

zone "eng.acme.com" {
type forward;
forwarders { 10.1.2.3; };
forward only;
};


-thanks

I don't believe you'll have any success trying to use forwarders from the top-level domain back into a sub-domain.

It sounds like you may not have properly set up delegation of the sub-domains on the top-level DNS server. If that is done properly nothing else is needed to be able to resolve a name for a host in one sub-domain from a host in another. There is a very straight forward discussion of setting up delegation of sub-domains in "DNS and BIND (O'Rielly & Assoc.).
