many hand-on routing workshops start with rip, though with the
warning "you will now learn why not to use rip." it makes it
easy to teach poison reverse, ... in a relatively small setting.
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.
Absolutely agreed, however, that such teaching also necessarily
involves emphatic shouting of "YOU WILL NOT TURN THIS ON IN YOUR
PRODUCTION NETWORK".
[ObAnecdote: I once heard of an airline reservations desk in Hong
Kong which had a backup connection to the airline's main centre of
operations far distant from Hong Kong, using dial-on-demand ISDN,
circa 1995. The monthly invoice for international ISDN charges that
followed a contractor's decision to "fix the router by turning on
RIP" was apparently an impressive thing to behold, especially given
the agressive ISDN idle tear-down configured on the router and
minimum 1-minute billing per call.]
