No, but UDP is, and RIP runs on top of UDP. Oh, so you mean there IS some sort of solid definition of 'protocol' for this discussion? See below...

Note my quotes around the word routing. The only protocol that people route is IP. Therefore, if you "route" all of the other protocols you mentioned, you must inherently route all protocols L4 on up that run on IP. Routing is done at L3. Therefore, if you want to talk about things running L4 and up, the question should be about filtering and not routing. That's my point...that if we're talking about which protocols are being routed, it's either "IP and IPv6" or "everything from L4 up that runs on IP", depending on how you take the question.
