That's all you should need to do.

Is the name of the subdomain server in the subdomain that it serves,
i.e. is it something like:

subdom.parent.  NS  ns.subdom.parent.

In that case, you also need a "glue record", i.e. an A record in the parent
domain:

ns.subdom.parent.  A  1.2.3.4

Otherwise, you have an infinite regress problem: in order to look something
up in the subdomain you have to query the subdomain server, but to get its
address you would have to query it.

This is all explained in the DNS & BIND book, in the section on Parenting.
