Using GTM as master with no DNS server

We are deploying a couple GTMs to act as the authoritative public DNS servers for a new domain. We aren't interested in doing any geographic load-balancing at this point, just hosting a few static A-...

A master zone within ZoneRunner is essentially going to be an authoritative zone for the device. Any queries directed to the GTM for a record in that zone will be answered by the GTM. You'll want a setup like this:

 

The parent provider zone (for example, company.com) will have NS records configured for your zone (for example, child.company.com) pointing to your two GTM appliances via hostname (ns1.child.company.com and ns2.child.company.com). You'll configure A records within your master zone (child.company.com) for ns1.child.company.com and ns2.child.company.com, corresponding to the public facing listeners on your GTMs.

 

So when a DNS server queries the parent zone at company.com and requests an NS record for child.company.com, the parent will hand back NS records of ns1.child.company.com and ns2.child.company.com. Then DNS servers will query your GTMs since these NS records correspond to your GTMs.

 

I hope this makes sense and I didn't ramble too much.

I think within your abc.co.in zone, you need to create your NS record as ns1.abc.co.in, and have your domain registrar configure delegation as such. Creating ns1.xyz.co.in within your abc.co.in zone isn't going to work.
