GR-IX drops RPKI invalids
by Michael Oikonomakos 06 Jul '20

06 Jul '20

Dear all, It has been a long journey but thankfully it has come to an end!!! We are happy to announce that as of today (06/07/2020) GR-IX route servers drop RPKI invalids for both our infrastructures in Athens & Thessaloniki. GR-IX [1] is a neutral and independent Internet Exchange in Greece, owned and operated by GRNET [2] (the Greek NREN). Please let us share with you the brief version of the story behind it and any lessons learned. - GRNET was an early supporter of RPKI. It started by signing ROAs for GRNET and their customers (all Greek Universities and Research Institutes). Moreover, it performed marking on each prefix received for further statistical / monitoring process. In the early days, GRNET was not dropping RPKI invalids, but put those prefixes with lower priority in their routing table. - GRNET & GR-IX were early supporters of MANRS [3] and successfully became a member of MANRS as a Network Operator & IXP respectively. - As of 10/2019, GRNET decided to start dropping invalid IPv4 and IPv6 RPKI prefixes received from GR-IX peerings and from GRNET upstream. No major issues were reported until now. - As of today, GR-IX drops invalid IPv4 & IPv6 RPKI prefixes on their route servers. We are using the BGP large communities proposed by euro-ix [4] in order to mark the prefixes accordingly. We noticed no prefix with RPKI invalid status which hasn't already been filtered by our route servers due to our strict IRRDB filtering. We would like to thank all our members (GRNET & GR-IX ones) for their help and support in this effort - either via simply signing their ROAs, or by participating in our tech mailing list and discussions we had during various fora. Internet was built of smaller or bigger ecosystems such as ours in Greece, in which we take great pride of its vibrant participation and technical expertise and are happy of being part of it. We do hope you’re staying safe and healthy during these hard times and wish you a great summer. Should you need any further information, please do contact us.

Ensuring RPKI ROAs match your routing intent
by Alex Band 01 Jul '20

01 Jul '20

Hi everyone, Over the last two years NLnet Labs has been working on free, open source RPKI software and research for the community, supported by the RIPE NCC Community Projects Fund, Brazilian NIR NIC.br and Asia Pacific RIR APNIC. I have an update that we’d like to share. When creating a ROA in RPKI, it can have an effect on one or more BGP announcements, making them either Valid, Invalid or NotFound. Understanding what exactly determines these three states is not immediately obvious, especially in the beginning. At times, this can make creating ROAs a bit of a shot in the dark. I’ve seen several examples in the past where an operator created a ROA in their RIR Portal, waited for it to be published and then checked in services like BGPMon or the HE BGP Toolkit to see if everything turned out as expected. This is why, during my time at the RIPE NCC, we put a lot of work into making it immediately obvious what the effect of a ROA is going to be on the BGP announcements with your address space. Several RIRs have followed in these footsteps since. I presented on this journey at NANOG 63 in 2015: https://archive.nanog.org/meetings/abstract?id=2500 Now, in my new adventure at NLnet Labs, we’ve gotten the same team together to make simple, intuitive ROA management for Delegated RPKI available for everyone, seamlessly across RIR regions. With Krill 0.7.1 ‘Sobremesa’ you can easily create and maintain ROAs in a user interface that incorporates all of the best practices and lessons learned over the last 10 years and monitor them in ways never before possible, such as through Prometheus.

The dangers of demonizing bogons 2019-08 : (Fwd: [ncc-announce] [news] Sanctions and the RIPE NCC: Status Update)
by Job Snijders 26 Jun '20

26 Jun '20

Dear group, This message is in context of 2019-08 and related policy proposals in other regions of the world. When the RPKI is changed from an "opt-in" to an "no opt-out" mechanism, things will break horribly. Christian's message should make that clear. Imagine that the sanctions progress in intensity, to a state where RIPE NCC must de-register the resources assigned to the 3 members on the sanctions list. Their resources would stop being assigned, and move into the unassigned pool. This means they'll end up on the SLURM file, and if *you* use that SLURM file you will NOT be able to communicate via the Internet with fellow humans who happened to be born into an unfortunate situation. For this reason I will not use such SLURM files, they have the potential to do far more harm than they are doing me good. https://labs.ripe.net/Members/job_snijders/dont-terminate-peoples-internet-… The people in charge will find a way to browse the web anyway (satellite, lease IPs from other places), where stuff like this really hurts is the small people that are trying to find information on the Internet about the state of the world. Please read the below and ask yourself whether it really is worth it to pursue 2019-08 or related policies in other regions. Kind regards, Job ----- Original message ----- From: Christian Kaufmann <exec-board(a)ripe.net> To: ncc-announce(a)ripe.net Subject: [ncc-announce] [news] Sanctions and the RIPE NCC: Status Update Date: Wednesday, June 24, 2020 13:09 Dear members, I want to briefly update you on the current situation involving sanctions, following my last email back in April[1]. In short, there have been no major developments and the situation is largely unchanged. However, to keep you informed, allow me to briefly run through this again. STATUS OF EXEMPTION REQUEST AND FROZEN MEMBERSHIPS In April, we mentioned that the RIPE NCC was seeking an exemption from EU sanctions regulation from the Dutch authorities. The authorities have indicated that their response will take longer than usual, possibly due to the COVID-19 situation. We will inform you when we receive a decision on our request. For the three members believed to be on the sanctions list, this means that their LIR accounts remain frozen and they remain unable to access RIPE NCC services. While this is not ideal, it does mean that their resources have not been deregistered. BANK TRANSFERS FROM IRANIAN AND SYRIAN MEMBERS My earlier email also mentioned that the RIPE NCC's bank had temporarily revoked its ability to receive bank transfers from members in Iran and Syria. Unfortunately, this restriction remains in place and will likely remain so until the RIPE NCC receives a response to its exemption request. As this will probably take longer than the 1 July payment deadline, the RIPE NCC is looking at ways to address this and will follow up with affected members directly. RIPE NCC EXECUTIVE BOARD POSITION This is also unchanged, but I think you'll agree that this is a good thing: "The Executive Board of the RIPE NCC believes that the means of communication should not be affected by political discussions or disputes. This includes the provision of correctly registered Internet numbering resources."[2] At our board meeting last week, we reaffirmed that the RIPE NCC is committed to pursuing all legal means to continue providing services to all of its members. As we have already stated, we believe the Internet is a critical tool for humanity and should not be affected by political discussions. I regret that we are not yet able to give a more positive update, we are doing all we can to resolve this issue. If you have any questions or comments for the board, please contact us at <exec-board(a)ripe.net>. Regards Christian Kaufmann RIPE NCC Executive Board Chairman [1] Sanctions and the RIPE NCC: Current Status and Executive Board Position: https://www.ripe.net/ripe/mail/archives/ncc-announce/2020-April/001413.html [2] Executive Board Resolution on Continuity of Services to all RIPE NCC Members: https://www.ripe.net/publications/news/about-ripe-ncc-and-ripe/executive-bo…

New on RIPE Labs: Route Flap Damping in the Wild?!
by Mirjam Kuehne 24 Jun '20

24 Jun '20

Dear colleagues, BGP Route Flap Damping and its use has been a controversial topic in the past. Recommendations have been revised multiple times over the past two decades and still differ from vendor default values. In this article on RIPE Labs Clemens Mosig and his co-authors dive into how Route Flap Damping is measured in the real world, uncover which configurations are in use, and provide parameter sets based on past recommendations for your router: https://labs.ripe.net/Members/clemens_mosig/route-flap-damping-in-the-wild Kind regards, Mirjam Kühne RIPE NCC

From Zero to RPKI Hero: Live Demo
by Nathalie Trenaman 17 Jun '20

17 Jun '20

Hi all, The community has teamed up to bring something very exiting to network operators around the world! This Friday, from 17:00 CEST, we are doing a live demo “From Zero to RPKI Hero” where we will show how to create ROAs, set up Routinator, RIPE NCC Validator, configure Juniper, Arista, Nokia and Cisco routers to perform RPKI Origin Validation. This has never been done before! And it will be live! People can join over Zoom: https://arista.zoom.us/s/93051476697 <https://arista.zoom.us/s/93051476697> <https://arista.zoom.us/s/93051476697 <https://arista.zoom.us/s/93051476697>> or join the Facebook live stream: https://www.facebook.com/events/183972346373123/186010836169274/ <https://www.facebook.com/events/183972346373123/186010836169274/> Later on, this will be uploaded to YouTube. Please note: This is not an event organised by any of the vendors, nor is it a commercial event. Just a bunch of techies (Ties de Kock, Florian Hibler, Greg Hankins, Jeff Tantsura, Orhan Ergun, Melchior Aelmans, Alex Band and Nathalie Trenaman) coming together to show “how it’s done” Best regards, Nathalie Trenaman

academic paper: "Peerlock: Flexsealing BGP"
by Job Snijders 15 Jun '20

15 Jun '20

Dear colleagues, An interesting paper has been made available as pre-print: "Peerlock: Flexsealing BGP" by Tyler McDaniel, Jared M. Smith, and Max Schuchard from the University of Tennessee. The paper probably is the most formal description of Peerlock so far. They even conducted active measurements to reverse-engineer what the state of peerlock deployment is in the global Intenet routing system. Abstract: https://arxiv.org/abs/2006.06576 PDF: https://arxiv.org/pdf/2006.06576.pdf Recommended reading! Kind regards, Job
