Survey on Segment Routing deployment
by Dekinder Florian 14 Mar '25

14 Mar '25

Hello RIPE community, I recently shared a survey (2 months ago) as part of a research project on segment routing (SR) deployment practices among network operators. The goal is to gain insights into how SR is currently deployed and managed across different ASes. If you are involved in SR management in your network and if you missed the first request, I would greatly appreciate your input. The survey takes no more than 5 minutes to complete. https://docs.google.com/forms/d/e/1FAIpQLSd9d77tMC_azhcfWWCMR_nHCBlfzu8VI-v… Thank you in advance for your time and contribution! Best regards, Florian Dekinder

Registry scoped members for RPSL set objects
by Sasha Romijn 21 Feb '25

21 Feb '25

Hello, We would like to share our draft "Registry scoped members for RPSL set objects" with the working group: https://datatracker.ietf.org/doc/draft-romijn-grow-rpsl-registry-scoped-mem… This draft addresses the ambiguity of references between sets in RPSL, where currently one set includes another by its RPSL primary key. As the same primary key may exist in multiple IRR registries, these references are ambiguous, while the referred objects sometimes have very different contents. There was some earlier discussion on the routing-wg list on this issue and how to resolve it, but it didn't lead to any practical solution. This new proposal adds a new attribute where references to other sets must be scoped to a specific IRR registry. Specific resolving and validation rules ensure that we keep backwards compatibility with older RPSL objects, authoritative servers, and resolvers. At the same time, it provides benefits even with partial deployment. We welcome your feedback and discussion, though preferably on the GROW mailing list: https://mailarchive.ietf.org/arch/msg/grow/mdoTvD2vQBZqsDO0VRWRo-ADD3c/ Sasha
