Hi Alexander, In my head, I had explicitly excluded the idea of taking this to the IETF. The reason beind that I can see all manor of problems arising from either trying to deprecate the attributes and/or trying to modify the FSM, during the transition period as networks upgrade their BGP implementations at different rates.
Networks will come to different conclusions about which path is the best path. Within a large network it will differ within a single network, as it takes time to rollout the BGP upgrade. There could be forwaridng loops too. Getting IETF approval, then getting vendor adoption, then getting most of the major networks to roll it out to reach critical mass; I can see that being a 10 year project. If someone really wants to take this to the IETF, probably the path of lesser resistance would be to get a new BCOP published which recommends everyone bleach the origin type to IGP to implicitly deprecate the attribute, and advise networks do things that avoid the FSM getting as far down the process as router ID. With kind regards, James Bensley (he/him) ________________________________ From: Alexander Zubkov <[email protected]> Sent: 22 October 2025 21:55 To: James Bensley <[email protected]>; [email protected] <[email protected]> Subject: bgp origin attribute ⚠️ Caution: This email originated from outside of your organization.

Have you thought already about making an RFC draft to not consider Origin attribute in the BGP decision process? It seems to be a reasonable next step. PS. And maybe Router ID as well. :) Regards, Alexander Zubkov Qrator Labs [CompanySignature] Inter..link GmbH | Boxhagener Straße 80, 10245 Berlin, Germany | Managing Directors: Marc Korthaus, Theo Voss | Commercial Register: Amtsgericht Charlottenburg, HRB 138876 | VAT ID: DE281288887 | Email: [email protected]<mailto:[email protected]> | Web: inter.link<https://inter.link>
