RIP has one property no "modern" protocol has.  It works on simplex =
links (e.g. high-speed satellite downlink with low-speed terrestrial =
uplink).

Is that useful?  I don't know, but it is still a fact.

I once had cause to write a RIP broadcast daemon while on-site with a
client; they had some specific brokenness with a Novell server and some
other gear that was "fixed" by a UNIX box, a C compiler, and maybe 20
or 30 minutes of programming (mostly to remember the grimy specifics of
UDP broadcast programming).  I do not recall the specific routing issue,
but being able to just inject a periodic "spoofed" packet was sufficient
to repair them.

I've got a RIPv2 daemon written in a few dozen lines of Perl
to do something very similar.

In other situations, RIPv2 has strong KISS appeal.
