Grid Setup: Zone Transfer vs. bloxSYNC [ Edited ]

[#1]

Dear Sir,

Do Infoblox appliances use bloxSYNC to synchronize their zones in a grid setup? Can zone transfer be used to synchronize zone files between grid members?

I am working on an airport project and one of the requirements is to use a dedicated interface for zone transfer. I understand, zone transferred can be configured to use LAN 2 interface, if required, but does the grid members use zone transfer if they are part of a grid? Also, can bloxSYNC can be configured to use a dedicated interface?

Our setup includes:

1. HA Grid Master
2. HA Internal DNS Servers
3. 2 External DNS Servers (no HA)

As always, appreciate the support provided.

Thanks,

Senthil Kumar
