I configured server B in WHM as a secondary DNS server.
Server A is the primary master DNS server.
I click the &Synchronize DNS Records With Primary Nameserver& link in B's WHM.
All of A's zone files get copied over to B.
However none of B's zone files get copied over to A, even though they don't exist in A.
How do I change this? I'm creating accounts in B and using A as my primary DNS server. However if A isn't taking any of B's newly created zones then what's the point of having this setup?
