<b>主题:</b> Soliciting suggestions and experiences from the community for RPKI-invalid filtering deployment<br><br><div>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.</div><div><br></div><div>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.</div><div><br></div><div>Questionnaire link: </div><div>https://qfreeaccountssjc1.az1.qualtrics.com/jfe/preview/previewId/70bbaf01-b4a6-4f7d-aac4-33cff5b135a3/SV_dj62hVBXcEy5ryC?Q_CHL=preview&Q_SurveyVersionID=current</div><div><br></div><div>Reference:</div><div>[1] Help Validate ROV Adoption Measurements from RoVista. https://labs.ripe.net/author/tijay-chung/help-validate-rov-adoption-measurements-from-rovista/</div><div>[2] 85% of MANRS Members Conformant to Actions 1 and 4. https://www.manrs.org/2023/01/85-of-manrs-members-conformant/</div><div><br></div><div>If you have any questions, concerns, issues, or comments, please send an email to qlc19@mails.tsinghua.edu.cn</div><div><br></div><div>Best,</div><div>Lancheng</div><div><br></div></blockquote>
