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

Hello, We have a circuit in MI1 that we are trying to relocate, but there's a crazy delay. Does anyone have the ability and desire to coordinate a Equinix cross connect and sell us DIA for 3-4months? Usage is 2-3Gbps Residential, we can use our own IPs/ASN if necessary. Eric

Re: Destination Preference Attribute for BGP

And you know what? Hashing / memory storage HAS been a problem with multiple vendors in many other contexts, not just BGP community stuff. Has nothing to do with "2023 hardware". You can bog down top of the line DDR5 memory pretty easily if you make certain coding choices. You can choose ( as you apparently have ) to just presume that a problem that happened before won't ever happen again. Prob not a great idea though.

[HELP] Opinion the Sparkle Scrubbing Center (AS6762)
by Anna Fernández 21 Aug '23

21 Aug '23

Hello folks, I would like colleagues' opinion on Sparkle/Telecom Italia's scrubbing center services (AS6762). I am interested in this type of service in Brazil, I heard reports that they will have a scrubbing center there in the next few days. What makes me curious is knowing the experiences of other colleagues, I met someone who used it and the report on their SOC did not make me excited to hire the service, it may have been a bad experience, so I ask my colleagues for their opinion. Best Regards.
