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.
While not the correct way to engineer a network, sometimes being able to
bring a client's network back on-line in a crisis is more important than
technical correctness. I feel reasonably certain that I would not have
been able to cobble together a quick solution if they had been relying
on OSPF, etc. A simple protocol can be a blessing. I concede it is more
often a curse.
