Direct protocol affects BGP

[Fabiano D'Agostino]

Hi all,
why if I disable the direct protocol the BGP routes are not
imported/exported? If I run show route, it is empty, while if I enable the
direct protocol show route has directly connected routes and BGP routes.
My configuration is very easy, two routers make a eBGP peering and they
import and export all routes. I am using Bird 2.0.7.
Thanks,

Fabiano
