That's a little dangerous! That means all ISP's are in the same AS. More than likely, as the days go by, there will be filtering issues as well as BGP policy issues, since a route reflector approach essentially makes all ISP's one ISP. This is the model the KIXP (.ke) took, and have since been trying to rectify the situation. Forget scaling, this is just not the way to do it. I worked with some .gh folk on this, and thought they'd be taking the more typical approach. > The full mesh approach will work for the cases where > you have operators who know exactly what they are > doing. Well, the requirements in the initial stages of the exchange point are not entirely heavy that you need a degree in the thing :), but I know folk in .gh who are capable of running BGP at a basic level. Peering with each other is like peering with a single router, except that you are repeating the configuration for different peers, and have more long term flexibility. > But it also invites undue meddling via industry > politics.

Should peering be mandatory, or not? At one of the workshops we did for .bw (their BINX is now up and running), one of the ISP's refused to peer with the other, and as much as they were being urged to by their ISPA, the last time I checked they hadn't reconsidered. Different networks will peer for different reasons. To be free and fair, forcing an ISP to peer with another isn't going help the IXP's cause. Mark.
