Direct protocol affects BGP

[Benedikt Neuffer]

Hi Fabio,

so the routes are in FIB (kernel) but maybe not in RIB (bird).

Can you provide me the output of "show route for <prefix> table all all"
where <prefix> should be the prefix configured on the connection or the
ip address of the neighbor.

Regards,
Bene
