the same argument can be made about using PNIs instead of IXPs for interconnection. Provisioned properly, most service providers aren't going to see much of a practical difference between connecting to their IXP over a switch and connecting directly with a router. For a larger organisations, it makes less sense to put a switch in the middle but let's face it, most organisations which connect to IXPs aren't giants. So yes: "YMMV". Mileage varies quite a good chunk across the sort of provider profile you see at IXPs. Don't write off something which makes plenty of sense for a small organisation just because it makes almost none for a large one. Nick
