What is a reasonable range for global BGP table size?
How big is the global BGP table running these days? 100K? 110K? Bigger? -Rob
A 'show ip bgp sum' at route-views.oregon-ix.net shows most providers have between 110k and 113k... On Wed, 17 Jul 2002, Rob Healey wrote:

Hmm. We don't filter, and 112942 network entries and 391859 paths using 25288182 bytes of memory On Wed, 17 Jul 2002, Jared Mauch wrote:

it appears to depend upon which hemisphere you get transit in :) Steve On Thu, 18 Jul 2002, Alex Rubenstein wrote:

We don't filter either and... 117800 network entries and 339843 paths using 23660948 bytes of memory "about 135k prefixes last i checked." is not what we see here from any of our upstreams. -Robert Tellurian Networks - The Ultimate Internet Connection http://www.tellurian.com | 888-TELLURIAN | 973-300-9211 "Good will, like a good name, is got by many actions, and lost by one." - Francis Jeffrey
I was going off my data analysis of route-views data. wc -l oix.home_as.out 135949 oix.home_as.out this file has prefix:home_asn (where home_asn is the last asn in the as_path. prefixes with inconsistent home_as will appear twice. this may be cause of some of your confusion. eliminating those brings it to 120131 prefixes) - jared On Thu, Jul 18, 2002 at 12:37:09PM -0400, Robert Boyle wrote:

Hi, Rob. ] How big is the global BGP table running these days? I'm seeing an average of around 115K prefixes. The delta isn't very high. You can see some data here: http://www.cymru.com/BGP Thanks, Rob. -- Rob Thomas http://www.cymru.com ASSERT(coffee != empty);
