The CCNA study guide does a real poor job (as does the cisco command reference) of describing exactly what the difference between mac-address-table restricted and mac-address-table permananet does. Resticted seems to just make sure that only a specific source mac can be plugged into a specific port But permanent seems to route frame with a specific destination mac out a specific interface (or interfaces) Which to me seems like routing, and I'm hard pressed to figure out why you would want to do that statically.
