If the pdns server is authoritive for the domain, every recursor in the
world will look at your pdns server when it want to ask about that
domain. Because the root and TLD will point them to your pdns server.

Thus so will your own recursor.

I suggest you set up a few domains in your recursor to point to your
pdns for the domains. The few domains you use internally (don't forget
your reverse DNS blocks).

Just in case you lose connectivity to the outside world and the external
root/TLD-servers can't be reached.

Well, I hope the above makes sense to you. Atleast if that is the setup
you want then it should not need any other configuration then what I
mentioned above.
