Microsoft DNS and BIND Secondary

I have a Microsoft DNS environment and Im introducing BIND as secondary servers.

I have added the new BIND servers as Name Servers on one of the Forward and one of the Reverse Lookup Zones on one of the Master Microsoft DNS servers. By doing this the BIND servers should replicate through to all the other Microsoft DNS servers within the environment. I have 20 different Forward Lookup Zones, 15 different Reverse Lookup Zones and 10 different Conditional Forwarders.

My questions are:

1.   Do I need to add the BIND servers to ALL of the 35 zones that I have within the environment? As BIND are secondary servers they should have all the zones as Microsoft DNS servers do, correct?

2.   Do I need to enable Zone transfers on ALL of the 35 zones that I have within the environment or being that I added the servers as Named Servers, the BIND servers will get the zone info for all 35 zones that way?

2a.   If I need to enable Zone transfers on ALL of the 35 zones, should I configure it to go to ALL the Named Servers or just the Master servers that I have listed for BIND to get zone info from?

Thank you in advance!!


CONDITIONAL Forwarder
zone "lab.com" {
  type forward;
  forward only;
  forwarders { ip-of-server1; ip-of-server2; };
};

Open in new window



FORWARD Lookup Zone
zone "appsdr.com" {
  type slave;
  masters { ip-of-server1; ip-of-server2; };
  file "/var/named/named.appsdr.com";
  allow-notify { none; };
  allow-transfer { localhost; p-of-server1; p-of-server2; };
  request-ixfr yes;
  masterfile-format text;
};

Open in new window



REVERSE Lookup Zone
zone "10.in-addr.arpa" {
  type slave;
  masters { ip-of-server1; ip-of-server2; };
  file "/var/named/named.10.in-addr.arpa";
  allow-notify { none; };
  allow-transfer { localhost; ip-of-server1; ip-of-server2; };
  request-ixfr yes;
  masterfile-format text;

Thanks for your comment.
Should I enable zone transfers to all servers on names servers tab or just to dedicated servers in the zone transfers tab?
