Dual-homed DNS question

I need to know the best way to design my DNS setup for a couple of production servers.  Each server has two NICs, one in the 10.1 domain and the other in the 10.2 domain.  The 10.2 NICs are connected to a separate switch so I can do large file transfers, backups, etc. without impacting the users who connect via the 10.1 switches.  These servers all, because of the backup software I am using, must be able to resolve each others names to 10.2 addresses.  No problem, just bring up named on one of them and populate it with the four names.

My question is this.  How do I then resolve the names of the other servers who have the same domain name, but have 10.1 addresses?  I don't want to have to maintain two DNS zones on two servers for all of the 10.1 nodes.

I tried forwarders, but I guess I don't fully understand what that option does.  What I want is to resolve the name on the 10.2 server, but if the name isn't found, pass the request along to the other server which is authoratative for the rest of the names.

Hope this makes sense.
