Re: So -- what did happen to Panix?
Here is what we propose in PGBGP. If you have a more specific route and its AS Path does not contain any of the less specific route's origins, then ignore it for a day and keep routing to the less specific origin. If it's legitimate the less specific origin should forward the data on for the day. We see about 30 of these suspicious routes per day. I imagine some of you will not like this sceheme. Please let me know why. Josh On 2/8/06, Jeffrey Haas <[email protected]> wrote: > > On Wed, Feb 08, 2006 at 04:37:31AM +0000, Christopher L.
