Deployments of Provider Backbone Bridging (PBB)
by Etienne-Victor Depasquale 25 Aug '23

25 Aug '23

Hello folks, Based on data I've gathered through quantitative and qualitative surveying, I can detect no application of Provider Backbone Bridging (MAC-in-MAC). Please bear with me while I clarify that I am not enquiring about Provider Bridging (QinQ). I would like to ask specifically about knowledge of deployments of PBB. If anyone would care to share data points, on- or off-list, I would love to know about them. I am open to anything on the subject of PBB's adoption that you are free to share with me. I am bound by GDPR and will anonymize any data that is not open for public disclosure. Thank you! Etienne -- Ing. Etienne-Victor Depasquale

Contact from Astound/Wave?
by Dan Mahoney 24 Aug '23

24 Aug '23

Hey there, could someone from Astound/Wave please contact me? A friend just moved in to a rental property at the end of a long private road in Ferndale, WA, and has spoken to her neighbors and gotten word that her neighbors in every direction got together and paid Wave to extend their network into the space, but Wave still claims that service is not available there. I need someone beyond the usual 800 numbers and web-lookup tool who has a clue about this and can tell us what the actual history is, and if such things allow people who weren’t privvy to the original extension run to use it. -Dan

*A (Tech) Road Less Traveled * *Cohen Shares How a Passion for Travel Led to a Career in Tech* As a 20-something U.S. citizen playing pro tennis in Europe during the late 1980s, a career in tech was not what Cohen envisioned for his future. Married and father of two, Principal Program Manager for Microsoft, Peter Cohen said he has been in the "convincing business" side of the Internet industry for more than two decades. However, a passion for travel and culture has steered his non-linear career. *READ MORE <https://www.google.com/url?q=https://nanog.org/stories/articles/a-tech-road…>* *Introducing the New 2023 Election System! * *NANOG Transitions to Ranked Choice Voting * To encourage more membership voting and provide more transparency in votes received, we are moving to Ranked Choice Voting for the 2023 election cycle. *LEARN MORE * <https://www.google.com/url?q=https://www.nanog.org/members/elections/ranked…> *Sponsor the NANOG 89 Hackathon!* *Unlock Innovation at the Nexus of Networking* Join us in catalyzing innovation, forging connections, and propelling the networking industry into uncharted territories.

JunOS config yacc grammar?
by Lyndon Nerenberg (VE7TFX/VE6BBM) 24 Aug '23

Any chance somebody out there has a yacc grammar that will parse a Juniper config files? My immediate interest involves v19.X on our EX4300s, but anything in the ballpark would save me having to write one from scratch. --lyndon

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

OFFS people, spare me the bikeshed. It was a simple yes/no question.

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.
