Running a routing protocol on a unix box doesn't mean you're using it as a
router.  Perhaps he just wants OSPF on a few servers so they can send
their packets more efficiently.  Consider a case where you have a few
access servers and unix servers on the same switch and a router connecting
that POP to your backbone.  Having a routing protocol on those unix boxes
means they can send packets directly to the appropriate access server (or
the router) rather than everything to the router, just to have it spit the
packets back out headed for an access server on that segment.
