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:

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.
