From henk at ripe.net Fri Aug 18 11:45:00 2006 From: henk at ripe.net (Henk Uijterwaal (RIPE NCC)) Date: Fri, 18 Aug 2006 11:45:00 +0200 (CEST) Subject: RPSL support for 32 bit ASN Message-ID: RPSL list, RFC2622 and 4012 say: An AS number x is represented as the string "ASx". That is, the AS 226 is represented as AS226. This was written assuming 16 bit (0-65536) AS numbers (ASN16). There is now a draft to expand the AS number space to 32 bits (ASN32, see draft-ietf-idr-as4bytes-12.txt) as well as proposals in the various regions to start deploying those (RIPE2005-08, ARIN 2005-9, APNIC 032-v2 and others) as of January 2007. Draft draft-michaelson-4byte-as-representation-01.txt suggests that ASN are written as: <16 msb in decimal>.<16 lsb in decimal> with the first part dropped for values <65536. (In other words, the AS are labelled 0, 1, 2, .... 65534, 65535, 1.0, 1.1, 1.2 ... 1.65535, 2.0). I can imagine that people will want to use 32 bit ASN in RPSL starting 1/2007. Question: How to adapt RPSL for this? Solutions: 1) Change the definition in RFC2622 to An AS number x is represented as the string "AS[0-9]+ or AS[0-9]+.[0-9]+. (In other words, follow the Michealson draft). 2) Other? If so, what? I guess in all cases, implementors will have to check that their implementations can deal with ASN >65535. Is there a WG where we can submit a draft with these extensions?

I should have made it clearer that the two comments were separate. I think that it would be best to reflect the usage in the draft but it might also be the case that the current software would "support" a single integer purely because the size of the number wasn't checked.

My next step is to cut an 02 draft and put it to Yakov Rechter/Susan Hares for discussion in IDR at San Diego. I've been led to believe this is the most appropriate WG for it to get signoff and move on from. cheers -George From william at elan.net Thu Aug 24 20:17:04 2006 From: william at elan.net (william(at)elan.net) Date: Thu, 24 Aug 2006 11:17:04 -0700 (PDT) Subject: Fwd: Re: RPSL support for 32 bit ASN In-Reply-To: <20060823174750.GB24822@nokia.com> References: <7.0.1.0.2.20060823112119.035181e8@ripe.net> <20060823174750.GB24822@nokia.com> Message-ID: On Wed, 23 Aug 2006, David Kessens wrote: > For the record, I am willing to sponsor this document as soon as IETF > has decided what the 'standard' notation is going to be.

That is, it will not come out of an IETF working group but will be contributed by an individual (Henk). This document would be last called so everybody has a chance to comment, and as you can see from the discussions among the CC'ed, a good set of people who are involved with RPSL in one way or the other have been involved by Henk.
