Date: Sun, 01 Nov 2009 09:25:34 +0900 From: Randy Bush <randy@psg.com> To: Christopher Morrow <morrowc.lists@gmail.com> In-Reply-To: <75cb24520910311612hf5cd2e1y647ee9d35eccdab9@mail.gmail.com> Cc: nanog@nanog.org Errors-To: nanog-bounces+nanog.discuss=bloom-picayune.mit.edu@nanog.org while i can understand folk's wanting to signal upstream using communities, and i know it's all the rage. one issue needs to be raised. bgp is a brilliant information hiding protocol. policy is horribly opaque. complexity abounds. and it has unfun consequences, e.g. see tim on wedgies etc. and this just adds to the complexity and opacity. so i ain't sayin' don't do it. after all, who would deny you the ability to show off your bgp macho? just try to minimize its use to only when you *really* need it. randy
