I'm not sure if Allen is joking. Anyway, I believe his email included
some 'IGRP derived' info.

Part of the info seems to include the largest size packet you probably
could send via this route without fragmentation by an intermediate
router/gateway/hop. This might prove helpful in investigating
performance problems possibly due to fragmentation. I seem to remember
such a discussion about 4-5 years ago somewhere on the net.

Please excuse me if I'm off base here, but I think that's the basis for
calculating & providing 'min MTU' info in a route cache.
