Hi all, At this point in time two candidates made themselves available to serve the community as Routing WG co-chair: Ben Cartwright-Cox and Alessandro Improta. I appreciate both candidates stepping forward. The following procedure will be used to select one candidate: step 1) The candidates are given 3 minutes of microphone time to introduce themselves to the working group and motivate their candidacy. step 2) After all statements have been heard, the working group is asked as many times as there are candidates to express support for the candidate through "IETF humming", or abstain through silence. step 3) The Routing WG co-chairs and RIPE community chairs delibrate together on their interpretation of the sound of the humming. step 4) If the humming appeared preferential to one of the candidates, the new co-chair has been found (procedure ends). If the humming could not be interpreted in a conclusive way, proceed to step 5. step 5) toss of a coin to overcome the tie-breaker (random selection) The procedure's objective is to gauge whether the working group has a clear preference for one or the other candidate, and if all candidates appear to be supported by the working group to make an arbitrary choice. The above procedure was agreed upon by Routing WG chairs & RIPE chairs. Execution of this process at the upcoming RIPE86 Routing WG meeting will serve as input into improving the description of the Routing WG chair selection document. Kind regards, Job outgoing co-chair Routing WG

Late Revocation of CA Certificates due to Bug in RIPE NCC CA Software
by Ties de Kock 17 May '23

17 May '23

Dear colleagues, As a result of a software bug introduced in our RPKI CA system on 16 May at around 08:49 UTC, our CA system failed to revoke certificates for members/End Users that lost their final resources. This issue affected two certificates, one containing a /22 and another containing a single AS Number. In violation of our CPS [0, Section 4.9.5], we did not revoke the affected certificates within eight hours of changing the resources. These certificates did not issue any leftover CA products (ROAs). A fix for this issue was deployed to production today, 17 May at 08:20 UTC, and the two certificates were correctly revoked at 08:29 UTC on 17 May. Since the /22 certificate involved the consolidation of resources and no ROAs were present, we believe there was no impact on the validity of prefixes. Similarly, there was no impact for the AS Number returned to the free pool. We have checked the prefixes affected by all transfers that happened during the time period the bug was present. No other certificates were affected: Either the CA still had resources, or there was no CA certificate for the member/End User to lose resources. To detect bugs like this and to prevent them from being introduced in the future, we will (1) improve the monitoring that verifies that the resources of the published certificates match the registry and (2) introduce tests that cover this scenario. Kind regards, Ties de Kock Specialist Software Engineer RIPE NCC [0]: https://www.ripe.net/publications/docs/ripe-751

Upcoming chair selection for the RIPE Routing Working Group
by Paul Hoogsteder 17 May '23

17 May '23

Dear Routing Working Group, As Job Snijders is going to step down as co-chair of the Routing WG we asked for volunteers, and I'm glad someone responded: Ben Cartwright-Cox. Chair selection is done during a RIPE Meeting (not on the mailing list), and we happen to have one next week in lovely Rotterdam: https://ripe86.ripe.net/programme/meeting-plan/ Our WG session will take place on Wednesday morning, 9AM CEsT. If you have questions about the chair selection process or want to volunteer please contact routing-wg-chairs(a)ripe.net, NOT this mailing list. Kind regards, Paul Hoogsteder co-chair of the RIPE Routing WG

Call for presentation Routing WG at RIPE86 (Rotterdam, Netherlands)
by Job Snijders 18 Apr '23

18 Apr '23

Dear RIPE Routing WG, This is a call for presentation proposals for RIPE 86! The RIPE 86 meeting takes place in about 66 days: https://ripe86.ripe.net/ We ask both the Working Group and RIPE NCC for presentation proposals for the eminent 1.5 hour Routing WG slot on Wednesday, May 24th, 2023. The Routing Working Group is concerned with all aspects of IP routing technologies. This includes dissemination and discussion of issues affecting operators, new technologies and new applications of current technologies, and discussion of concerns relevant to inter and intra-AS routing. A non-exhaustive list of topics of interest includes BGP, Routing Security, RPKI (ROV, ASPA, BGPsec), LSR (OSPF/ISIS), Anycast, and BGP Monitoring (MRT, BMP). When you submit a proposal please also include slides for the chairs to review. If you've presented similar material elsewhere please share with us when and where. Proposals can be sent to routing-wg-chairs(a)ripe.net We look forward to seeing you all in Rotterdam! Kind regards, Job, Ignas, Paul RIPE Routing Working Group Co-Chairs

stepping down as routing-wg co-chair & transition
by Job Snijders 28 Mar '23

28 Mar '23

Hi all, The "Routing WG Chair Selection Process" [1] suggests chairpersons at some point step down to allow for new candidates to step up. Having been a co-chair of the Routing WG for over 3 years, I think the upcoming RIPE86 meeting will be a good time for me to step down to make room for new people! It's been a lot of fun, thanks to you all. If you're interested in helping organize the Routing WG sessions at RIPE meetings as co-chair together with Paul and Ignas, please reach out to routing-wg-chairs(a)ripe.net for more information. I'll set aside time to help with a co-chair transition. Kind regards, Job Routing WG co-chair [1]: https://www.ripe.net/participate/ripe/wg/active-wg/routing/routing-wg-chair…

RPKI Quarterly Planning Q2 2023
by Ties de Kock 21 Mar '23

21 Mar '23

Dear colleagues, The next quarterly plans for RPKI can now be found at: https://www.ripe.net/manage-ips-and-asns/resource-management/rpki/rpki-plan… This quarter, we'll continue building an audit framework for RPKI and start making improvements to the RPKI dashboard and rsync repositories. We hope that by providing these plans, we can better inform the community of the ongoing developments on RPKI and get feedback on our work. If you have any comments or questions, we hope you'll discuss them with us on the list, or if you prefer, you can always contact the team directly at rpki(a)ripe.net . Kind regards, Ties de Kock Senior Software Engineer RIPE NCC

BGP Best Path data from different RIS
by Ehsan Ghazizadeh 20 Mar '23

20 Mar '23

Hi everyone I'm trying to write a python script to fetch bgp best path data for my prefixes from different locations. Apparently ripe stat only returns the full routing table not the best path, also connecting via telnet to routeviews routers and parsing bgp commands output is not an ideal method, so I was wondering is there any other method to achieve this (preferably using api)?

Improved timeliness of RIS dump files
by Emile Aben 07 Mar '23

07 Mar '23

Dear colleagues, We are planning to replace the pipeline that generates MRT dump files publicly available from the RIPE NCC. The new pipeline will have significantly less delay, and also some changes on the structure of the MRT file format [*]. Files in the newer format are available for testing here: https://www.ris.ripe.net/dumps-per-rrc-rest/prototype/ We have received feedback from MRT parser implementers that these files work fine for their parsers, but in case you haven't tested your MRT parser implementation, we ask you to test the new files before we make the switch. Our plan is to make this switch on 3 April 2023. After we make the switch the bview files available at our main location for downloading MRT files will be generated using the new pipeline and we will be able to produce these files in a more timely manner. Kind regards, Emile Aben RIPE NCC [*] These changes are documented here: https://ris.ripe.net/docs/40_Prototypes/15_per_rrc_dumps.html, but beware at this point we are only changing the files, not the frequency of dump files, nor putting the API in production. We did not receive feedback about these, but please let us know if you find them useful.
