Atleast that is my take on it.. That is my impression. My point is that DFZ routers don't store any topographical information - so the paper seems to have nothing to do with today's routers. > The thing I don't get is how does that relate to prefixes.

Maybe so - that's for the authors and others to respond to. An AS could span the entire world, and have routers all over the Net, with one or more of these routers advertising a particular prefix. As I understand the operation of the interdomain routing system, its not good enough to forward the packets whose destination addresses match this prefix to any router which belongs to this AS. They should be forward to the one or more routers which advertises the prefix. - Robin _______________________________________________ rrg mailing list [email protected] http://www.irtf.org/mailman/listinfo/rrg
