The 12.2SRE for RSP720 on 7600 is going to be available shortly and it will support 4B ASNs. It was communicated a number of times on cisco-nsp@ for those who subscribe it and did care.

Even if i guess everybody is aware this is thankfully coming at some stage, and i personally find the shortly definition late 2009 a bit disappointing, i find the point being another: In late 2006 it was more or less monumentally announced that the paths of the switch and the router were to get separate: the 6500 and = SXH releases on one side, the 7600 and = SRA releases on the other. Then i see 32-bit ASNs being kindly implemented on the switch first, in SXI - with SRD for the router being released roughly in parallel; and one can amuse himself by reading issues people stumble upon with SXI. OK, a fuck-up on the way - it can happen: http://www.cisco.com/warp/public/707/cisco-sa-20090729-bgp.shtml And finally, yes, 32-bit ASNs for the router will come: by the end of this year and on a new release: SRE. Which, re-phrased from an operator point of view, essentially means: a candidate release for a production deployment is not less than another 1 year away. And frankly pages like the one below, with no mention of plans for the 6500/7600 platforms whatsoever, are not encouraging at all: http://www.cisco.com/en/US/prod/collateral/iosswrel/ps6537/ps6554/ps6599/data_sheet_C78-521821.html Cheers, Paolo
32-bit AS numbers
Hi all, As you (hopefully) know, as of 1-1-2010, the RIRs will only be giving out 32-bit AS numbers. I'm writing an article for Ars Technica about this, and I was wondering about the perspective of network operators who may be faced with customers with a 32-bit AS number in the near future, and how the vendor support for 32-bit AS numbers is working out. If you send me info in private mail, let me know your title/ affiliation and whether I can quote you or not. Iljitsch
RE: 32-bit AS numbers
Hi Iljitsch- This statement isnt entirely correct. Im not sure if this is just a word smithing error in your email or if the management of this issue in the ARIN region isnt well known. I can only address the ARIN region but in that region if there is a 16 bit ASN in the free pool it will be given out before a 32 bit one. They are going to manage the ASN free pool by lower bit number out first. Granted if zero 16 bit ASN's are in the pool then the only thing going out at the time would be a 32 bit ASN. However, I just wanted to clarify for the ARIN region that 16 bit ASN assignments will not be halted. If they exist in the free pool they will be used. Cheers!

RE: 32-bit AS numbers
We are running into the same issues regarding 12.0 train for 12008 GSR w/PRP-2's. Even though there are IOS's that have a fixed 4 Byte ASN code...it has other bugs in NSF-SSO that we use here extensively. So hence the reason we are waiting to upgrade.
