Bind not forwarding all requests

Hello,

yes I have a db.root file which contains Root servers.
/etc/resolv.conf is configured to ask to him self.

Forward is not configured at zone level, it is specified in
named.conf.options
In an option{} block, so I guess this should apply for all, if not specify
at the zone level.

Here is my conf for root zone :

// prime the server with knowledge of the root servers
zone "." {
        type hint;
        file "/etc/bind/db.root";
};


should I try to force forwarders in zone "." ?
