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.
