So, I am trying to not use routing instances. Is there a way to tell a
BGP group to use a different primary RIB than inet.0 (for family inet
unicast)? There is the rib-group directive but it enforces that the
first member of the rib-group to be the primary RIB.

There is also "topology", but the documentation says that routes are
still placed in the default RIB.
