RIPE 80 - proposed Routing WG Agenda
by Job Snijders 06 May '20

06 May '20

Dear group, We have been given the opportunity to organise a 30 minute Routing Working Group session at the virtual RIPE 80 meeting. Please read https://ripe80.ripe.net/attend/how-to-participate/ carefully, this virtual meeting will not be as simple as just showing up in person. The expectation is that people register beforehand in order to participate via the Zoom platform. We propose the following agenda for RIPE 80: 5 minutes - opening / welcome / agenda Routing WG Chairs poll: request to working group to approve minutes from RIPE 79 minutes are available here: https://www.ripe.net/participate/ripe/wg/routing/minutes/routing-working-gr… 5 minutes - "DB Task Force requests input from Routing WG on what to do with RPSL in RIPE DB" Nick Hilliard 5 minutes - "Update on Policy Proposal 2019-08 "RPKI ROAs for Unallocated and Unassigned RIPE NCC Address Space" Massimiliano Stucchi, Melchior Aelmans, and Martijn Schmidt. 5 minutes - "PeeringDB 'never_via_routeservers' option" Johannes Moos 5 minutes - "RPKI deployment update" Ben Cox 5 minutes - filler space Some of the above presentations are pre-recorded, our hope is that by not doing everything 'live', we will an overall smoother experience switching between presenters. We personally do not expect this lightning talk session format to become the norm, we expect to be able to provide the group with more time and opportunity to share work and insights with each other at a later point. See you next week! :-) Kind regards, Job & Paul

New on RIPE Labs: RPKI: Past, Present and Future
by Mirjam Kuehne 06 May '20

06 May '20

Dear colleagues, With RPKI experiencing a huge growth in its deployment and becoming a key part in the operations of the Internet, we have been investing significant amount of resources in making its infrastructure resilient, secure, and highly available. Recent outages have raised concerns about the maturity level of this relatively new technology and we have taken these incidents very seriously. We are now in the process of making long-term, significant improvements to our technical infrastructure, operational procedures, and software development processes to meet the growing expectations of the technical community worldwide. Please find more details on RIPE Labs: https://labs.ripe.net/Members/felipe_victolla_silveira/rpki-past-present-an… Kind regards, Mirjam Kühne RIPE NCC

RIPE NCC Executive Board election
by Ronald F. Guilmette 17 Apr '20

17 Apr '20

Greetings all, I know that all is not right with the world right now, and that most of you, like me, have much more pressing things on your minds right now, but someone just sent me the following link and I cannot exactly ignore it: https://www.ripe.net/participate/meetings/gm/meetings/may-2020/confirmed-ca… I would like to call everyone's attention to the last of the three candidates who have, it seems, "qualified" as candidates for open seats of the RIPE NCC Executive Board. As I have already said, I know that things are bad in the world right now, but I must ask this question: Is there really no one other than these three candidates who is willing and/or able to stand for the three open seats on the RIPE NCC Executive board... three open seats that will be voted on at the next general meeting, 13-15 May 2020 ? If not, then it seems that RIPE NCC will soon be following in the new tradition, established first by AFRINIC only last year, of placing well and widely known crooks on it board. I desperately hope it won't come to that, but that is not for me to decide. The decision is in your hands dear friends. Regards, rfg

Subject: RPKI ROA Deletion: Post-mortem
by Nathalie Trenaman 06 Apr '20

06 Apr '20

Dear colleagues, After our accidental deletion of RPKI ROAs on Wednesday evening, we have a post-mortem report to share with the working group. Following an update to our internal registry software on 1 April at 18:16 (UTC+2), 2,669 ROAs were deleted from Provider Independent (PI) address assignments. This was caused by our registry software classifying these assignments as not-certifiable. From our logs, we can confirm that these blocks never left the RIPE Registry, and within 15 minutes the registry was back to normal. However, by that time the ROAs had already been deleted and could not be restored without intervention from our engineers. Affected users with alerts set up in the LIR Portal received a notification email on 31 March at 22:23, stating that their ROAs were missing. Some of these users emailed our Customer Service Department to ask why their ROAs had been deleted. As this was outside of office hours, our staff did not discover the issue until the next morning. Our engineers were able to reinstate all of the missing ROAs by 13:15 on 2 April. We then informed our membership via ncc-announce and notified the affected users directly. We have since implemented stricter checks on both our registry and RPKI software. We are also investigating whether any of these PI assignments suffered from route-leaks or hijacks after their ROAs were deleted. We apologise for any inconvenience this may have caused and we are taking all necessary steps to ensure this does not happen again in the future. Kind regards, Nathalie Trenaman Routing Security Programme Manager RIPE NCC

NTT/AS2914 enabled RPKI OV 'invalid = reject' EBGP policies
by Job Snijders 04 Apr '20

04 Apr '20

Dear Routing WG, Exciting news! Today NTT's Global IP Network (AS 2914) enabled RPKI based BGP Origin Validation on virtually all EBGP sessions, both customer and peering edge. This change positively impacts the Internet routing system. The use of RPKI technology is a critical component in our efforts to improve Internet routing stability and reduce the negative impact of misconfigurations or malicious attacks. RPKI Invalid route announcements are now rejected in NTT EBGP ingress policies. A nice side effect: peerlock AS_PATH filters are incredibly effective when combined with RPKI OV. For NTT, this is the result of a multiyear project, which included outreach, education, collaboration with industry partners, and production of open source software shared among colleagues in the industry. Shout out to Louis & team (Cloudflare) for the open source GoRTR software and the OpenBSD project for rpki-client(8). I hope some take this news as encouragement to consider RPKI OV "invalid == reject"-policies as safe to deploy in their own BGP environments too. :-) Kind regards, Job

Re: [routing-wg] 2019-08 Review Phase (RPKI ROAs for Unallocated and Unassigned RIPE NCC Address Space)
by JORDI PALET MARTINEZ 04 Mar '20

04 Mar '20

Hi Job, I don't think I'm the one that should calculate that. However, if we have an alternative proposal with the SLURM file, it can be calculated (approximately) as part of the analysis impact that will be needed as well, right? May be anyone from the community that already has done that job and integrated the SLURM in their routers, can provide an estimate cost, and then multiply it for the number of all the RIRs members? I believe (I may be wrong) that the AS0 is much cheaper to implement by RIPE NCC even if it is several thousand euros, than the number of worldwide folks that will need to use the SLURM in addition to RPKI (for non-AS0).

Can you provide us with an estimate of the cost to the collective community if this proposal is *not* implemented as RPKI ROAs but just as SLURM file instead?

2019-08 Review Phase (RPKI ROAs for Unallocated and Unassigned RIPE NCC Address Space)
by Petrit Hasani 03 Mar '20

03 Mar '20

Dear colleagues, Policy proposal 2019-08, "RPKI ROAs for Unallocated and Unassigned RIPE NCC Address Space", is now in the Review Phase. The goal of the proposal is to ask the RIPE NCC to create ROAs with origin AS0 for all unallocated and unassigned address space under its control. The proposal has been updated following the last round of discussion. Version 2 of the proposal includes a specification for the RIPE NCC to create all AS0 ROAs under a specific Trust Anchor. The RIPE NCC has prepared an impact analysis on this latest proposal version to support the community’s discussion. You can find the proposal and impact analysis at: https://www.ripe.net/participate/policies/proposals/2019-08 https://www.ripe.net/participate/policies/proposals/2019-08#impact-analysis And the draft documents at: https://www.ripe.net/participate/policies/proposals/2019-08/draft As per the RIPE Policy Development Process (PDP), the purpose of this four week Review Phase is to continue discussion of the proposal, taking the impact analysis into consideration, and to review the full draft RIPE Policy Document. At the end of the Review Phase, the Working Group (WG) Chairs will determine whether the WG has reached rough consensus. It is therefore important to provide your opinion, even if it is simply a restatement of your input from the previous phase. We encourage you to read the proposal, impact analysis and draft document and send any comments to <routing-wg(a)ripe.net> before 20 March 2020. Kind regards, -- Petrit Hasani Policy Officer RIPE NCC

RPKI Outage Post-Mortem
by Nathalie Trenaman 02 Mar '20

02 Mar '20

Dear colleagues, From Saturday 22 February at 08:24 (CET), any newly created, modified, or deleted ROAs (176 in total) could not be added to our publication server due to a disk problem. From that moment on, all the data was stored on the database, but the publication did not happen. The disk did not report any problems and, therefore, no engineer was alerted of this incident. Due to the disk problem, starting from Sunday 23 February at 09:10 (CET), our CRL expired and our repository could not be properly updated. This was reported to us on Monday 24 February at 11:44 (CET). Immediately, our engineers fixed the disk problem, however, since the CRL expired, all underlying objects also expired. Depending on the Relying Party software an operator used, this abnormal behaviour appeared differently. Initially, our engineers tried to do a full re-population of the RPKI repository, but unfortunately, this did not update the CRL in the validation tree. At 15:03 (CET), we performed a full CA key-roll, which was completed at 21:02 (CET) and resolved the problem. At 19:58 (CET), all objects in the backlog were published. We apologise for any inconvenience this may have caused and we are taking all the necessary steps to ensure this incident does not appear again in the future. Kind regards, Nathalie Trenaman Routing Security Programme Manager RIPE NCC

Looking for recommendations
by Nathalie Trenaman 17 Feb '20

17 Feb '20

Dear colleagues, As presented at the last Routing WG meeting at RIPE 79, the RIPE NCC is planning on carrying out an extensive technical and procedural audit on RPKI throughout this year. We are currently looking for an organisation that can help us with this exercise. Particularly, we are looking for an organisation that is familiar with the RPKI audit frameworks and ,ideally, has extensive knowledge on BGP routing and cryptography. We are planning on starting the consultation in two weeks and are looking forward to your recommendations. Kind regards, Nathalie Trenaman Routing Security Programme Manager RIPE NCC

An agreed community value to signify test invalid prefixes would help. Maybe a ripe doc (399 or 706) could be updated? Maybe a discussion point for next meeting.

RPKI: Forthnet drops invalids
by Tassos Chatzithomaoglou 10 Feb '20

Hi to everyone, I would like to inform you that it's been almost one month since Forthnet started dropping invalid prefixes on all peering/transit links, either national or international. It's important to note that during this month we haven't received any complaints. Having monitored the invalid prefixes for more than a year and experimenting with routing them across different links, we decided that it was time to move to the next phase and start dropping prefixes that are declared as invalid in the RPKI ecosystem. Two were the main reasons that helped us take the drop decision: a) during the last year our volume of invalid prefixes traffic decreased from ~1% of total traffic to less than 0,2%, b) we updated our prefix validation policy by including a whitelist (until we evaluate SLURM) in order to bypass issues quickly if/when they arise. Note #1: in the context of the above actions we have noticed that invalid prefixes used for testing purposes have recently begun to grow (each large provider creates one?). This may lead to incorrect conclusions in the future (at least in terms of prefixes, since i don't expect traffic from those). Maybe these invalid prefixes should have some extra "attributes" in order to be recognized more easily while troubleshooting. Note #2: In order to increase adoption of a similar policy, maybe MANRS should be updated to promote dropping invalids. If i'm not mistaken, their current action is about creating ROAs only. -- Tassos

new tool: rpki-ov-checker

I wrote a simple tool to figure out what kind of invalid a rpki invalid is, this can aid people in understanding the impact of "invalid == reject" routing policies. Only "invalid_unreachable" routes present an operational issue in my opinion, IP addresses covered by "notfound" or "valid" less specific routes will still be reachable. You pass it a file name (or via stdin) with one prefix and origin ASN per line (white space separated) representing your full BGP RIB, and then you can grep specific for the task at hand to extract the info you need: $ rpki-ov-checker full_rib | fgrep -f customer_prefixes | grep invalid | sort -R | head invalid_covered_by_notfound 123.101.0.0/21 4809 covering route: 123.101.0.0/16 4134 invalid_covered_by_valid 46.3.74.0/24 134121 covering route: 46.3.0.0/16 207636 invalid_unreachable 83.231.209.0/24 3949 invalid_unreachable 124.30.247.0/24 9583 invalid_covered_by_valid 125.21.232.0/24 9730 covering route: 125.21.0.0/16 9498 invalid_unreachable 120.29.92.0/24 17639 invalid_unreachable 31.40.164.0/24 200872 invalid_covered_by_notfound 45.12.139.0/24 40676 covering route: 45.12.136.0/22 35913 invalid_covered_by_valid 122.160.178.0/24 24560 covering route: 122.160.0.0/16 24560 invalid_covered_by_valid 61.90.251.0/24 21734 covering route: 61.90.192.0/18 7470 NTT is using this to figure out who we need to help fix their ROA or correct their BGP announcements.
