Sorry, I just re-read your post and realized what you were actually asking and I am sure there is someone more qualified than I to answer this, but, my understanding is that the FIB is a destination prefix cache used in high-speed forwarding or "switching" like CEF and the RIB is basically an older(?) version used by slower process switching and other CPU based decision making processes. Anyone feel free to correct this as needed.
