Maybe Im wrong but hey if you are taking 200megs from any > one ASN I would hope you knew about it. Also, that method has the same "knowing the routes" problem as netflow. Whereever you are getting your list of ASN's route ASN.*"'s routes, there is pretty much no way they are accurate (for an ASN of ANY size). You would have to statically route (or otherwise inject routes with a specific nexthop) a list of their customer prefixes that would have to be manually transmitted. -- Richard A Steenbergen <[email protected]> http://www.e-gerbil.net/ras GPG Key ID: 0xF8B12CBC (7535 7F59 8204 ED1F CC1C 53AF 4C41 5ECA F8B1 2CBC)
