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-records. The GTMs don't seem to want to do this (or I'm too unfamiliar with the interface to figure out how).

 

 

Could someone give me a hint as to how to set up a new domain and then add a couple A-records to it directly. Everything on F5s site talks about doing a zone-transfer from an existing DNS server, which we don't have.

 

 

I'm pretty familiar with DNS/BIND, but not at all with F5-GTMs.

 

 

Thanks

 

 

Derek

    Hey Derek did you look into zonerunner?

    Can any one explain me what is the use of Master server while creating Zone. And if I have two different zone on GTM with two different NS record for both zone, so I want that when ever I do DNS watch for NS for any of the zone (domain) its should resolve with both Ns.

    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.

      Cory I will make it more clear for you what is my requirement. Take an E.g I have a zone created on my GTM i.e xyz.co.in, within the same zone xyz.co.in I have created the NS record i.e ns1.xyz.co.in and I have added A record for the Same NS which is Self IP of GTM within the same Zone. Now I have created one more Zone say abc.co.in , now within abc.co.in zone I have created different NS record i.e NS1.abc.co.in and added A record within the zone which is Self IP of Another GTM. Now my concern is when I do DNS watch for record NS for abc.co.in it should show me both NS record i.e NS record of abc.co.in and NS record of xyz.co.in I have inform my domain registrar to add NS record for abc.co.in for NS. Action plan from my side- I tried creating NS record (ns1.xyz.co.in) in zone abc.co.in however it not allowing me to do it.

      One more thing I missed out, when I do DNS watch of NS record for abc.co.in it get resolved by both NS but the output which DNS watch gives out , over there I cannot see.

      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.
