Thank you for your answer! I'm sorry, but I don't clearly understand
what you want to say? Does this feature limitation of unbound
is by-design? And can it be fixed by any reconfiguration of primary DNS
server which is running BIND? Or there is a hope that developers of unbound
will made a transparent-forward feature.
Just for note, djbdns works properly in this case, it gets by
including required zone to forward section. In other case it resolves
and cache zone via root servers.
