redundant DNS setup with bind_dlz possible ?

[Andreas Oster]

Hello all,

I am currently have a samba4 setup with bind9 as DNS server
running on the same machine using the bind_dlz module provided
by samba4. I am now curious if it is possible to set up a
redundant/second samba4/bind9 DC for redundancy. I know that
the AD part is no problem but what about the DNS part ? Will
the zone infos be replicated between the two DCs ? What do I
have to configure to add the new DC/bind9 as a secondary DNS ?
How would secure DNS updates be handled ?

Thank you for your kind help

best regards

Andreas
