RIS modifications for 4-byte ASNs on 27 March
by Erik Romijn 28 Mar '07

28 Mar '07

[Apologies for duplicates] Dear Colleagues On 1 January 2007, we began assigning 4-byte Autonomous System Numbers (ASNs). We need to modify the Routing Information Service (RIS) and RIS raw data dumps to include these in its output. You may need to update any tools that parse RIS output. We will switch one Remote Route Collector (RRC) to 4-byte ASN supporting software on 27 March 2007, somewhere between 09:00 and 13:00 (UTC). We plan to switch the other RRCs to 4-byte ASN supporting software on 28 March 2007, between 09:00 and 17:00 (UTC). Details of the changes to the RIS can be found at: http://www.ripe.net/projects/ris/docs/asn.html If you have any questions, please send an e-mail to <ris(a)ripe.net>. Regards, Erik Romijn Information Services Department RIPE NCC

RIS Maintenance Announcement: Thursday 22 March, 2007
by Erik Romijn 20 Mar '07

20 Mar '07

[Apologies for duplicate e-mails] Dear Colleagues, On Thursday, 22 March 2007, there will be planned maintenance on the Routing Information Service (RIS). This work will make the RIS database compatible with 4-byte Autonomous System Numbers. At 16:45 (UTC), the RIS database will stop inserting data. Between 17:00 and 18:00 (UTC), the database servers will be stopped twice for about 30 minutes. All RIS tools, except the Looking Glass, will be unavailable for up to one hour. Data collection will continue during the maintenance. When the system restarts, it may be a few hours until all the stored updates are inserted. We thank you for your patience and apologise for any inconvenience this may cause. If you have any questions about this work, please e-mail us at: ris(a)ripe.net Regards, Erik Romijn Information Services RIPE NCC

Update to RIS raw data format for 4-byte ASNs
by Erik Romijn 15 Mar '07

15 Mar '07

Dear Colleagues, This is an update concerning 4-byte Autonomous System Numbers (ASNs). An IETF draft has been released describing a new version of the MRT format, used for RIS raw data. We have published a new version of libbgpdump to support this, which can be downloaded from: http://www.ris.ripe.net/source/ There is at this stage no set date on which 4-byte ASNs will appear in the RIS. The current raw data does not use the new format. Details of the changes to RIS for 4-byte ASNs, including more information on the new raw data format, can be found at: http://www.ripe.net/projects/ris/docs/asn.html If you have any questions, please send an e-mail to <ris(a)ripe.net>. Regards, Erik Romijn Information Services Department RIPE NCC
