Automatically Synchronize between 02 slave name server?

[synthetic5995]

Hi guy,

I'd like to config this topology:

Master DNS ---recursive---> Slave DNS 01 ---auto-sync---> Slave DNS 02

I can do the first step of this topology:

Master DNS ---recursive---> Slave DNS 01

But can not do the next step:

Slave DNS 01 ---auto-sync---> Slave DNS 02

I thought about rescission between 02 slave Server but It will only update if I modify 1 existing zone, it can NOT update if I add a new zone. Does anybody do this solution? Please give me an idea

Thank You!
