DNS Cluster - Configuration

Community Support DNS
1

It is possible to create the following scenario for a DNS cluster:

  • Server 1: Hosting
  • Server 2: Hosting
  • Server 3: Hosting
  • Server A: MasterDNS
  • Server B: SlaveDNS

Flow:

  • Server 1 creates a DNS zone and sends it to Server A (MasterDNS).
  • Server A synchronizes the DNS zone with Server B (SlaveDNS).

The goal is for multiple hosting servers (Server 1, Server 2, Server 3) to send their DNS zones to Server A, which then automatically synchronizes with Server B.

The current issue I’m facing is that Server 1 successfully sends the zone to Server A, but Server A is unable to synchronize with Server B.

I would like to confirm if this scenario:

  • Server 1 >> Server A >> Server B
  • Server 2 >> Server A >> Server B
  • Server 3 >> Server A >> Server B

is indeed possible, and how I could resolve the synchronization issue between Server A and Server B.

edit: for now to simplify i made

Host.x (master) > NS.x(slave) works in that way

Server A do not communicate to Server B, instead servers 1, 2 and 3 communicate to both Server A and B

Follow these instructions:

Of course, I had already changed the flow before the response and it is already working.

Master > Slave A / Slave B
