Unnumbered interfaces are not supported officially,
but it may still work..

A while ago it was possible to use 'route' to add a rout eto a p2p
interface by name and not assign it any addresses.
thus packets would still be passed across the link without it having
any addresses. (this is great for not wasting adresses)

I do not know it this still works, asd I have not tested it for
a long time (several years)

from memory the 'route' man page still  specifies how to do the route end
of thing.

you might try it and get back to us to let us know it it still works.
(it has to be a point-2-point interface, e.g. a sync serial card)
