So who do you blame...the RFC or the vendor that ignores it? Dropping the session seems to break the "be conservative in what you send and liberal in what you accept" suggestion. If you know someone else will ignore the rules (there's always someone) breaking due to their error kind of sucks. -- ---------------------------------------------------------------------- Jon Lewis *jlewis@lewis.org*| I route System Administrator | therefore you are Atlantic Net | _________ http://www.lewis.org/~jlewis/pgp for PGP public key_________ ---------- Forwarded message ---------- Return-Path: <if@sil.at> Received: from mailhost.mmaero.com (mailhost.mmaero.com [208.152.224.3]) by redhat1.mmaero.com (8.11.6/8.9.3) with ESMTP id f984S0Z24869 for <jlewis@redhat1.mmaero.com>; Mon, 8 Oct 2001 00:28:00 -0400 Received: from waste.silverserver.co.at (waste.silverserver.co.at [194.152.178.7]) by mailhost.mmaero.com (8.11.2/8.11.2) with ESMTP id f984Rxp20147 for <jlewis@lewis.org>; Mon, 8 Oct 2001 00:28:00 -0400 Received: from ikarus (ikarus.sil.at [194.152.178.41]) by waste.silverserver.co.at (8.11.6/8.11.6) with ESMTP id f984Roi31471 for <jlewis@lewis.org>; Mon, 8 Oct 2001 06:27:50 +0200 Date: Mon, 8 Oct 2001 06:27:51 +0200 (MEST) From: Ingo Flaschberger <if@sil.at> X-Sender: chaoztc@ikarus To: jlewis@lewis.org Subject: Re: BGP noise tonight?

(over routers VendorX). rfc-compliant routers dropped the peering session after receiving this malformed route ebone has contaced the provider and he has already fixed this announcement. thnx & bye, Ingo -- "I worry about my child and the Internet all the time, even though she's too young to have logged on yet. Here's what I worry about. I worry that 10 or 15 years from now, she will come to me and say 'Daddy, where were you when they took freedom of the press away from the Internet?'" --Mike Godwin
