RIP also has the advantage that a worked, non-trivial example of the protocol can fit on a whiteboard, which makes it a reasonable way to teach the concept of a routing protocol to a classroom full of people who have never heard of such at thing.
Which is exactly the reason why I mentioned RIP as a routing protocol to start with. Using RIP instead of OSPF or IS-IS has 2 advantages: one is the simplyness of the concept and the second one you already mentioned:
Absolutely agreed, however, that such teaching also necessarily involves emphatic shouting of "YOU WILL NOT TURN THIS ON IN YOUR PRODUCTION NETWORK".
You learn why not to use RIP in an early stage of your career. Mentioning the terms "router-lsa", "network-summary-lsa" or "nssa-lsa" to a person who potentially does not even know the difference between a distance-vector and a link-state protocol has no positive effect on the learning curve. -- Sabri please do not throw salami pizza away
