Andrew,
(& all of the ASs behind them) have withdrawn more specific routes. If you could identify the home-ASs of the withdrawn nets, that would probably be more helpful & more accurate. --asp () uunet uu net (Andrew Partan)
During this tranisition from the classful world to the classless, home ASs still have meaning. It does not seem clear that home ASs will be relevant when we treat all routes as classless entities, because most assignments can be further subdivided. There will be no base unit such as class A, B or C on which to hang the home AS tag. We may want to move from "one net/one home AS" to "prefix and length/ announcing AS" - since an AS downstream or upstream may aggregate a subset or superset. I'm not commenting directly on your suggestion on how to express meaningful information about the specific nets that AS 701 has withdrawn from its announcment to AS 690, but trying to explore how we should look at keeping information about classless entities. These lists (regional-techs and bgpd) seem like the right place to discuss what information the operators need in a classless routing world. --Elise - - - - - - - - - - - - - - - - -
