The best I have come across is the Looking Glass at http://www.usenet.net.net/lg.cgi. Obviously, ignore the 0/0 route. "203.109.156.69" (the peer on that LG) appears to be an APE-connected router. Thats all I know. Perhaps someone else can shed some more light on this?
If there is a better way of doing this without having any of my own BGP sessions I'm all ears.
How do those ISP's who have a the same upstream(s) for intl and natl differentiate between the two for billing? Do they differentiate between them?
One way to do this is to have two connections to their upstream. One learns all the upstreams domestic routes, the other learns default only. Thus if there is a route in the table for it, it's domestic out interface A, otherwise it'll take the default route, international, out interface B. How they actually bill that though, I couldn't tell you. Tim Harman
