You may have many DECnet areas on the same segment, but each area
should have its own router. The cisco interface can only have one
DECnet address, thus can be the router for only one DECnet area, as
an area router must be in the same area that it is going to route
for. You could designate one of your VAXen an area router for the
other area though.
