On the Seattle Internet Exchange (SIX) we have ARIN-assigned addresses that we use on the Layer 2 fabric (your type 2 above). Hopefully the addresses aren't being announced at all, although we sometimes have to chase down people that announce it.I've had to deal with exchanges like this in the past, and frankly they have always been a pain for the support organization. You see, customers use tools like mtr or Visual Traceroute that do a traceroute and then continuously ping each hop. Many of these customers don't have a default route, or default to their _other_ provider. These tools end up showing 100% loss at the exchange, as they get the traceroute response and then can't ping it. They then open a ticket, and your support organization has to explain to them how all of this works and why it isn't the real cause of their problem.

My preference is that the exchange get an ASN, peer with everyone (e.g. from the route server) and announce the exchange prefix.
i do not like route servers or peering with strange things. treat the exchange as an internal route and announce it within your net and to your customer cone. randy
