One late comment --
OP stated that the companies were exchanging 'sensitive' traffic. I suspect
that they di *NOT* want this traffic to route over the public internet -if-
he private point-to-point link goes down. if they're running any sort of a
dynamic/active routing protocol then -that- route is going to disappear
if/*WHEN* the private link goes down, and the packets will be subject to
whatever other routing rules -- e.g. a 'default' route -- are in place.
This would seem to be a compelling reason to use a static route -- insuring
that traffic _fails_ to route, instead of failing over to a public internet
route, in the event of a link failure.
