by Job Snijders 15 Jun '20

15 Jun '20

Dear colleagues, An interesting paper has been made available as pre-print: "Peerlock: Flexsealing BGP" by Tyler McDaniel, Jared M. Smith, and Max Schuchard from the University of Tennessee. The paper probably is the most formal description of Peerlock so far. They even conducted active measurements to reverse-engineer what the state of peerlock deployment is in the global Intenet routing system. Abstract: https://arxiv.org/abs/2006.06576 PDF: https://arxiv.org/pdf/2006.06576.pdf Recommended reading! Kind regards, Job

RPSL
by ripedenis＠yahoo.co.uk 30 May '20

30 May '20

Colleagues Just a comment on the RPSL issue from the RIPE 80 session today. RPSL has little to do with the accuracy of data in the RIPE IRR. RPSL is just a language. Assuming you understand the language, it is your choice whether or not you maintain your data and keep it accurate and up to date. If we were to change from RPSL to something else the data would not necessarily be of any better quality. But it would be 'non standard' compared to all the other IRRs. Changing RPSL, as a means of inputting and outputting routing data, is not something that can be considered unilaterally within the RIPE Database. Perhaps a different question to ask could be, "is all the routing information contained in the RIPE Database still meaningful, useful and necessary (regardless of the language)?". cheersdenis co-chair DB-WG

by Mirjam Kuehne 08 May '20

08 May '20

Dear colleagues, In less than two years from now, the number of IPv4 prefixes in the global BGP routing table will hit the one million figure. Should you be worried? Read Berislav Todorovic's RIPE Labs article to find out: https://labs.ripe.net/Members/berislav_todorovic/the-1m-day-is-not-that-far… Kind regards, Mirjam Kühne RIPE NCC

RIPE 80 - proposed Routing WG Agenda
by Job Snijders 06 May '20

06 May '20

Dear group, We have been given the opportunity to organise a 30 minute Routing Working Group session at the virtual RIPE 80 meeting. Please read https://ripe80.ripe.net/attend/how-to-participate/ carefully, this virtual meeting will not be as simple as just showing up in person. The expectation is that people register beforehand in order to participate via the Zoom platform. We propose the following agenda for RIPE 80: 5 minutes - opening / welcome / agenda Routing WG Chairs poll: request to working group to approve minutes from RIPE 79 minutes are available here: https://www.ripe.net/participate/ripe/wg/routing/minutes/routing-working-gr… 5 minutes - "DB Task Force requests input from Routing WG on what to do with RPSL in RIPE DB" Nick Hilliard 5 minutes - "Update on Policy Proposal 2019-08 "RPKI ROAs for Unallocated and Unassigned RIPE NCC Address Space" Massimiliano Stucchi, Melchior Aelmans, and Martijn Schmidt. 5 minutes - "PeeringDB 'never_via_routeservers' option" Johannes Moos 5 minutes - "RPKI deployment update" Ben Cox 5 minutes - filler space Some of the above presentations are pre-recorded, our hope is that by not doing everything 'live', we will an overall smoother experience switching between presenters. We personally do not expect this lightning talk session format to become the norm, we expect to be able to provide the group with more time and opportunity to share work and insights with each other at a later point. See you next week! :-) Kind regards, Job & Paul

New on RIPE Labs: RPKI: Past, Present and Future
by Mirjam Kuehne 06 May '20

06 May '20

Dear colleagues, With RPKI experiencing a huge growth in its deployment and becoming a key part in the operations of the Internet, we have been investing significant amount of resources in making its infrastructure resilient, secure, and highly available. Recent outages have raised concerns about the maturity level of this relatively new technology and we have taken these incidents very seriously. We are now in the process of making long-term, significant improvements to our technical infrastructure, operational procedures, and software development processes to meet the growing expectations of the technical community worldwide. Please find more details on RIPE Labs: https://labs.ripe.net/Members/felipe_victolla_silveira/rpki-past-present-an… Kind regards, Mirjam Kühne RIPE NCC
