Need help with straight forward DNS solution

We are running a pair of BIGIP's v12.1.4.1 in a HA pair in a single data center.

 

We want to use the BIGIP as a master DNS server and allow a secondary provider to get slave updates from our BIGIP as the master.

 

I have been looking as some tutorials and all of them mention DNS Express. I do not see any DNS Express in v12.

 

I have gotten as far as:

 

-Creating a zone in zone runner.

-Creating a listener on an internal IP, which I have confirmed responds to queries of the zone in created in my zone runner.

 

My understanding is that what I have setup right now is just a very basic bind server, not DNS Express or any high performance DNS caching engine.

 

What do I do from here?

Has DNS Express been renamed to "Delivery -> Nameservers "?

 

Other question: Are there tmsh commands to modify zones? Or does it all need to be done through the gui?

    I think I have this sorted now:

     

    Listener: This is the DNS virtual server, and it will go directly to the local Bind server if a DNS Express zone doesn't exist. (I think this caused part of my confusion).

     

    Nameserver list: This is your list of nameservers that DNS Express will communicate with , whether to receive or to send NOTIFY messages, so in order to pull from the local bind server, you need to add a nameserver here with address 127.0.0.1.

     

    Zone list: DNS Express zones, Allow notify from 127.0.0.1 in order to pull from local bind server. Zone Transfer Clients to push to other secondaries.

     

    Zone runner: Local bind zones. Where the DNS Express will pull from if you tell it to pull from 127.0.0.1
