Since when is BGP a bug-free protocol? Let's not forget the BGP best path selection algorithm itself is broken (there are circumstances under which it will NEVER converge on a best path see ietf draft on IDR route oscillation). Not to mention the various malformed AS-Path bugs which have shown up over the years. I took a vendor class once where they made us do a lab where we had to run BGP w/o an IGP, in a later revision of the class they removed that lab because they decided it was too much of a nightmare even for a lab environment. -----Original Message----- From: Iljitsch van Beijnum [mailto:iljitsch@muada.com] Sent: Tuesday, September 03, 2002 10:39 AM To: alex@yuriev.com Cc: nanog@merit.edu Subject: Re: AT&T NYC On Tue, 3 Sep 2002 alex@yuriev.com wrote:
That is why their route is *nailed* via BGP to the router that *always* provide connectivity to them. If they have to move, BGP injectors are your friends. Takes seconds.
Talking about things that take seconds: would you mind sharing your BGP hold time values with us? Iljitsch van Beijnum
