DNS Setup for Open Directory Children

I am curious. I have setup a server as an Open Directory Master. Works great! DNS is functional, KDC works, and I'm able to login on both Mac and PC without a hitch. Now what I would like to do is add two additional servers for AFP network home directories. They would be children to the OD Master. How I would setup the DNS on them? Would I set it up identical to the way I setup the OD Master Server, except for the names of the servers? Your suggestions/help is graciously appreciated!
