Even without anycast, an ECMP shouldn't hash on the ECN bits. Doing so will split the flow over multiple paths; avoiding that is the whole point of doing the flow-based hashing in the first place. Anycast "only" turns a potential degradation of TCP performance into a hard failure... :) -Toke

Providing geofeed info to Google
by Hugo Slabbert 18 Sep '23

18 Sep '23

Google folks: I see historical reference to needing to use the Google Peering Portal ( http://peering.google.com) if you need to provide Google with geofeed info for GeoIP info on network blocks, ref https://mailman.nanog.org/pipermail/nanog/2015-May/075229.html. Is that still the case? Are there any avenues to provide Google with geofeed info if you're *not* currently peering with 15169? Or to get access to just the geofeed update portion of the Peering Portal? -- Hugo Slabbert

Soliciting suggestions and experiences from the community for RPKI-invalid filtering deployment
by Lancheng Qin 24 Aug '23

24 Aug '23

Hello, we have done a worldwide measurement to identify which ASes have propagated RPKI-invalid prefixes. We find an interesting phenomenon that some ASes may perform RPKI-invalid filtering only at partial interfaces (e.g., provider interfaces, customer interfaces, and peer interfaces). Although there are other studies [1, 2] noting the same phenomenon, little is known about why some network operators perform different filtering policies at different interfaces. We are trying to figure out the reasons and summarize the optimal deployment policy for RPKI-invalid filtering. To this end, we create an anonymous questionnaire and hope you can help fill out it. Questionnaire link: https://qfreeaccountssjc1.az1.qualtrics.com/jfe/preview/previewId/70bbaf01-… Reference: [1] Help Validate ROV Adoption Measurements from RoVista. https://labs.ripe.net/author/tijay-chung/help-validate-rov-adoption-measure… [2] 85% of MANRS Members Conformant to Actions 1 and 4. https://www.manrs.org/2023/01/85-of-manrs-members-conformant/ If you have any questions, concerns, issues, or comments, please send an email to qlc19(a)mails.tsinghua.edu.cn Best, Lancheng
