Multiserver DNS setup question

[spottraining]

Hi

Situation is fallowing:
I have one VPS in UK, where I have hosted main domain, let say domain.com. There I have nameservers ns1.domain.com and ns2.domain.com

Now I have second VPS in US, and I want to setup there ns3.domain.com and ns4.domain.com.

Multiserver is setupt and its adding zones etc.

But I don't understand right now - how I can add these ns3.domain.com and ns4.domain.com to second server.

I cannot add domain.com to second server, because it is added already in first server and Its gives error, that DNS zone exist in first server.
So I cannot make new nameservers under reseller level.

What is the right way to set up these new two nameservers?
And how I can add this possibility, that when I add domain to one of servers - it will add automatically 4 nameservers.

Something I found myself. Lets see - will everything work fine or not. Right now I am waiting with DNS resolving problems - its takes time.

What I have done, you can read there:

Maybe is not all correct, but at least I can add domains to both servers and its adding 4 nameservers as I want.


EDIT: Right now everything seems to work Even Eenet (Estonian top level domain registrar) automatic check shows, that all works fine. Domain has 4 nameservers, all nameservers works fine, all reverse lookups works also fine.
