Recently Completed BGP Study on "Peerlock"/Defensive Filtering
by Tyler McDaniel 12 Aug '20

12 Aug '20

Hello! My colleagues and I at the University of Tennessee recently completed a study on the “Peerlock” route leak protection system ( https://archive.nanog.org/sites/default/files/Snijders_Everyday_Practical_B…) and related defensive filtering techniques. Specifically, we probed for evidence of these systems on the control plane and attempted to locate filtering sites. Additionally, we evaluated the system's effectiveness in simulation. The pre-print of this paper is available at: https://arxiv.org/abs/2006.06576. While this work was previously mentioned here by Job Snijders, we want to make an additional push for comments from network operators. Our experimental design and findings in Section 3 may be of some interest. Most importantly, if any of the Tier 1 networks could confirm or challenge our findings with respect to their filter placement, that would be enormously helpful! We realize that this information is often secret/under NDA, but providing some element of ground truth would assist us in correctly evaluating our work. Thank you!

RIPE Stat routing info
by Sergey Myasoedov 07 Aug '20

07 Aug '20

Hello, For the every IPv4/v6 network I'm checking, RIPE Stat gives me "announced": false result. I'm observing this since last hour or two. Is this the outage or output format change in the RIPE Stat? Thank you. -- Kind regards, Sergey Myasoedov

2019-08 Policy Proposal Withdrawn (SLURM file for Unallocated and Unassigned RIPE NCC Address Space)
by Petrit Hasani 09 Jul '20

09 Jul '20

Dear colleagues, The policy proposal 2019-08, "SLURM file for Unallocated and Unassigned RIPE NCC Address Space" has been withdrawn. This proposal aimed for the RIPE NCC to publish a SLURM file (Simplified Local Internet Number Resource Management with the RPKI), containing assertions with the origin “AS0” for all unallocated and unassigned address space under our control. The proposal is archived and can be found at: https://www.ripe.net/participate/policies/archived-policy-proposals/archive… Reason for withdrawal: The WG Chair felt that raised concerns remained unaddressed and that there was a strong opposition against the proposal in the community. Kind regards, -- Petrit Hasani Policy Officer RIPE NCC

2019-08 Review Phase (SLURM file for Unallocated and Unassigned RIPE NCC Address Space)
by Petrit Hasani 08 Jul '20

08 Jul '20

Dear colleagues, Policy proposal 2019-08, “SLURM file for Unallocated and Unassigned RIPE NCC Address Space", is now in the Review Phase. The proposal aims for the RIPE NCC to publish a SLURM file (Simplified Local Internet Number Resource Management with the RPKI), containing assertions with the origin “AS0” for all unallocated and unassigned address space under our control. The proposal has been updated following the last round of discussion. Version 3 of the proposal has moved from instructing the RIPE NCC to create ROAs to creating a SLURM file for use with Relying Parties/Validators. 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 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 23 June 2020. Kind regards, -- Petrit Hasani Policy Officer RIPE NCC

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. Best regards, Michalis [1]: https://www.gr-ix.gr <https://www.gr-ix.gr/> [2]: https://grnet.gr/en/ <https://grnet.gr/en/> [3]: https://www.manrs.org <https://www.manrs.org/> [4]: https://www.euro-ix.net/en/forixps/large-bgp-communities/ <https://www.euro-ix.net/en/forixps/large-bgp-communities/>
