- 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.
