He`s quite right; we've had *lots* of trouble with ppp connections
that have any netmask other than 255.255.255.255; the router appears
to get completely munged, and adds any route within same class C
as the target (i.e., any route I'm likely to add on a network this small)
to that interface.

An alternative:  Perhaps route should let us specify which interface to use?
This would be a great feature.
