My reading of the Routing spec indicates "no" but I'm unsure of the meaning of the term "nearest level 2 router," so perhaps it is permitted. The implementation that I'm maintaining (which is an Ethernet level 1 router) will forward to an area router outside its area. The area router (a VAX) accepts and routes the message. A VAX Level 1 router on the other hand, would have forwarded only to an area router in its own area. So, I would correct this seeming error, but I'm worried that it may actually be a feature, or it may actually be the correct behaviour. .........o . o--+-----o . o | 1 Cambridge Center Nik Langrind .
