The RIBs which the control plane protocols populated are normally dictated
by the address family. In the case of multiple topologies, a specific RIB
(as identified by name) will need to be explicitly associated with the
topology in the control plane protocol as opposed to being connected to
the control plane protocol at a higher level.
