Correct. And there you have minimum frame spacing requirements (IFG) and (e.g. with 10Base2 networks) minimum distance between stations attached to the bus to allow CSMA/CD work correctly. I'm not aware of any BGP timing stuff that makes it inherently explode at a certain amount of routes. So what we ACTUALLY talk about is the fear that control planes (and associated forwarding plane adjacency lookup systems) won't be able to keep up with the granularity growth in routing information. Which is a different thing than "we have a BGP scaling problem". Best regards, Daniel -- CLUE-RIPE -- Jabber: [email protected] -- [email protected] -- PGP: 0xA85C8AA0
