Setup of Ns3.domain.com and Ns4.domain.com as slave nameservers

[topdog]

I was wondering how I'd setup 2 additional name servers, but as slave servers?
I have ns1.domainname.com and ns2.domainname.com, as an example, setup already as primary name servers. How, then, can I add a second machine, running ns3.domainname.com and ns4.domainname.com as slaves, and also add those 2 new NS servers to DA for all to use?

For make slave i suggest you to search in this forum for master2slave technology for have nameserver not using DA.
