John, Speaking just for myself, I can say that the intent was not crystal clear for me – may be my personal problem, of course.
I have looked up the latest version of the 7432bis draft, and I see that the authors have added the highlighted text in Section 7.11: [RFC8214<https://www.rfc-editor.org/info/rfc8214>] defines and requires this extended community ("L2-Attr"), to be included with per-EVI Ethernet A-D routes when multihoming is enabled. To me this suggests that that the intention probably was not so clear for other people as well😊 My 2c, Sasha From: John Scudder <j...@juniper.net> Sent: Tuesday, March 5, 2024 3:17 PM To: bess@ietf.org Subject: [EXTERNAL] Re: [Technical Errata Reported] RFC8214 (7837) This looks like a candidate “hold for document update”. The original document doesn’t seem to be in error, the erratum is just suggesting some editorial improvements/clarifications. Note that RFC 2119 keywords are not mandatory [*] in IETF specifications, what’s important is that the intent is clear, and I think the intent is crystal clear with the lowercase “mandatory“. Unless there’s disagreement, I’ll verify this as HFDU later this week. —John [*] see what I did there? > On Mar 5, 2024, at 5:50 AM, RFC Errata System > <rfc-edi...@rfc-editor.org<mailto:rfc-edi...@rfc-editor.org>> wrote: > > > > The following errata report has been submitted for RFC8214, > "Virtual Private Wire Service Support in Ethernet VPN". > > -------------------------------------- > You may review the report below and at: > https://urldefense.com/v3/__https://www.rfc-editor.org/errata/eid7837__;!!NEt6yMaO-gk!ECfJun-NPxU03B9Sfleq6xIj3IAePWsksETEL7ltxPlKDab3vqjlsXLZwlk3CGcfbqzdDpIW8cKMZwUTyuXDWw$<https://urldefense.com/v3/__https://www.rfc-editor.org/errata/eid7837__;!!NEt6yMaO-gk!ECfJun-NPxU03B9Sfleq6xIj3IAePWsksETEL7ltxPlKDab3vqjlsXLZwlk3CGcfbqzdDpIW8cKMZwUTyuXDWw$> > > -------------------------------------- > Type: Technical > Reported by: Alexander ("Sasha") Vainshtein > <alexander.vainsht...@rbbn.com<mailto:alexander.vainsht...@rbbn.com>> > > Section: 3.1 > > Original Text > ------------- > This document defines a new extended community [RFC4360], to be included with > per-EVI Ethernet A-D routes.
