Hi, this would at least help to get rid of many old routing engines around the world :) ... or people would keep their "learn nothing smaller than /24" filters in place. Also an option - but not for companies who act as an IP transit provider. 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 Justin Wilson - MTIN Gesendet: Freitag, 02. Oktober 2015 16:32 An: NANOG Betreff: /27 the new /24 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.
