interface to BGP

[Maria Matejka]

Hello!

Your config only _allows_ this prefix to be exported but doesn't load it from anywhere.

If any address of 192.0.2.0/24 is assigned to a local interface, you may generate the route by "protocol direct".

If you added the route to kernel by hand, you can use "learn" inside the "protocol kernel" block.

Last but not least, you may just create the route with "protocol static".
