Welcome to the real world ... Cisco SUP720-3BXL Cisco RSP720-3BXL and even the new and shiny SUP2T only supports 1 Mio routes (dicvided to IPv4 MPLS, IPv4 VRF, IPv4 global routes, etc). I guess this is still the truth: there are at least a few ten thousand of these devices running big parts of the internet. Take a look at some big players network - e.g. Level3. Their customer access routers in Slovakia, Austria and Germany are still based on the Cisco 6500/7600 platform. Of course there are many other vendors and platforms available which do NOT have this limitations. But there are also at least a ton of vendors on the market with exactly the same limitation :(. best regards Jürgen Jaritsch Head of Network & Infrastructure ANEXIA Internetdienstleistungs GmbH Telefon: +43-5-0556-300 Telefax: +43-5-0556-500 E-Mail: JJaritsch@anexia-it.com Web: http://www.anexia-it.com Anschrift Hauptsitz Klagenfurt: Feldkirchnerstraße 140, 9020 Klagenfurt Geschäftsführer: Alexander Windbichler Firmenbuch: FN 289918a | Gerichtsstand: Klagenfurt | UID-Nummer: AT U63216601 -----Ursprüngliche Nachricht----- Von: NANOG [mailto:nanog-bounces@nanog.org] Im Auftrag von Mike Hammett Gesendet: Freitag, 02.

If someone's network can't match that today, should I really have any pity for them? ----- Mike Hammett Intelligent Computing Solutions http://www.ics-il.com Midwest Internet Exchange http://www.midwest-ix.com ----- Original Message ----- From: "Matthew Kaufman" <matthew@matthew.at> To: "Mike Hammett" <nanog@ics-il.net> Cc: "NANOG" <nanog@nanog.org> Sent: Friday, October 2, 2015 10:48:29 AM Subject: Re: /27 the new /24 Cheaper than buying everyone TCAM Matthew Kaufman (Sent from my iPhone)

A /24 isn't that expensive yet...

I was in a discussion the other day and several Tier2 providers were talking about the idea of adjusting their BGP filters to accept prefixes smaller than a /24. A few were saying they thought about going down to as small as a /27. This was mainly due to more networks coming online and not having even a /24 of IPv4 space. The first argument is against this is the potential bloat the global routing table could have. Many folks have worked hard for years to summarize and such. others were saying they would do a /26 or bigger.
However, what do we do about the new networks which want to do BGP but only can get small allocations from someone (either a RIR or one of their upstreams)?
Just throwing that out there. Seems like an interesting discussion.
