In Cisco fast switching, the cache is pulled from the router FIB, *not* the BGP RIB. Nor is the FIB a direct derivative of the BGP RIB. The router FIB is constructed from *multiple* protocol RIBs including the connected RIB, the static RIB, the OSPF RIB, etc.
While technically true this neglects the point that in real networks, the BGP-derived subset of the FIB tends to dominate (for large values of "dominate").
