Thank you Ben,"With no forward {} the path for blah.bar.foo.com directed at
server A will be A > C > B"Do you see any reason why I would use this non
optimal path ?
In your example, how would C contact B, there would be a zone forward ?Regards

If you load foo.com on server A and delegate bar.foo.com to server B with a
global forwarder of server C you resolution will vary depending on forward
first vs forward only and forwarders {}.
With no forward {} the path for blah.bar.foo.com directed at server A will be A
> C > BWith forward {} the global forward will be short circuited for foo.com
and below resulting in a path of A > B

Thank you Ben for your answer
My server uses a global forwarding
I don't understand what you wrote"If it is master for a foo.com and also has
global forwarding it will use the global forward for any delegated child
domains under foo.com unless they are also loaded locally."
If my DNS is autoritative, why would I use a forwarding ?
For my sub domains I use delegationssub.mydomain.com NS
ns.sub.mydomain.comns.sub.mydomain.com A 1.1.1.1
What's the difference between the global forward for delegated child domains
and the delegation I do ?
Thank you

This would only change behavior if the server has global forwarding.
If it is master for a foo.com and also has global forwarding it will use the
global forward for any delegated child domains under foo.com unless they are
also loaded locally. The forward{} turns off global forwarding for that branch
of the tree.

Hello,
If my DNS is master/slave for a zone, why would I want it to use forwarders.
In other terms why would I wantzone "mydomain.com"
{
type master;
file "zones/master/com/mydomain.com ";
allow-update { acl; };
};
Instead of (forwarders {};)zone "mydomain.com"
{
type master;
file "zones/master/com/mydomain.com ";
allow-update { acl; }; forwarders {};};
Why would I want to forward requests if I'm autoritative for the zone ?
Thank you for those who can hightligh this point.
