I would say this the other way around, all exchange point blocks should be transited by someone. Back in the day, things like the mae-east FDDI were originated by a half dozen AS's. Why? If you had "full routes", but didn't connect to the mae, you could traceroute but not ping it, and things of that nature. It confused people. Of course, the inconsistent announcements were also an issue. The right thing is for each exchange point to be announced by one AS. I'm not sure if I favor having one AS per exchange, or one AS for all exchanges, but the point is the same. The AS should announce the route. The AS should get transit (possibly over the exchange) from one or more players. The exchange operator should run the box "announcing" the exchange. -- Leo Bicknell - bicknell@ufp.org - CCIE 3440 PGP keys at http://www.ufp.org/~bicknell/ Read TMBG List - tmbg-list-request@tmbg.org, www.tmbg.org
