This draft does not propose that intermediate node add extension header. - If this is not clear to you, please read the draft. - If it's clear, please let's stick to technical comment on _this_ draft. Bringing irrelevant points to the discussion is really not helping (both the discussion and the argument). This draft does not propose that intermediate node add/or remove arbitrary extension header. This draft, and more specifically the PSP flavor [1], is about removing the SRH header by an SR EndPoint. - with regards to PMTUD, can you clarify how reducing the size of the packet break PMTUD? And if there is an impact, let's remember that this is the source of the packet which instruct the SR EndPoint to remove the SRH. - with regards to AH, the SRH specification explicitly states that the use of SRH with AH by an SR source node is _not_ defined [2]. I don't think you can break something which is not working/defined. That been said, as an individual contributor, I think the PSP section should explicitly raise that point.

Again, thank you for that, I believe this is useful. But while this errata is not reviewed and accepted, RFC 8200 stands as is. --Bruno > Thanks! > > Cheers, > -- > Fernando Gont > SI6 Networks > e-mail: [email protected] > PGP Fingerprint: 6666 31C6 D484 63B2 8FB1 E3C4 AE25 0D55 1D4E 7492 > > > > > -------------------------------------------------------------------- > IETF IPv6 working group mailing list > [email protected] > Administrative Requests: https://www.ietf.org/mailman/listinfo/ipv6 > -------------------------------------------------------------------- _________________________________________________________________________________________________________________________ Ce message et ses pieces jointes peuvent contenir des informations confidentielles ou privilegiees et ne doivent donc pas etre diffuses, exploites ou copies sans autorisation.
