	I would agree.  Folks doing this are being very silly with their
configuration, the added load to their direct port should be expected, as
they are providing transit, the fact that they can cheat a bit and
not have their router take the switching load is just a nice thing.

unfortunate that the small folks like this are ruining it for themselves
because they don't have a real NOC.
