Please refer to https://www.ietf.org/iesg/statement/discuss-criteria.html for more information about IESG DISCUSS and COMMENT positions. The document, along with other ballot positions, can be found here: https://datatracker.ietf.org/doc/draft-ietf-bess-evpn-vpws/ ---------------------------------------------------------------------- COMMENT: ---------------------------------------------------------------------- [ For -11 / -12 ] This document is very heavy on the acronyms, and could do with some expanding of these -- for example, the document starts out with "This document describes how EVPN can be used...". I'm no MPLS VPN person, so much time was spent searching to try figure out what everything meant. I also agree with Spencer's "In multihoming scenarios, both B and P flags MUST NOT be both set. " being hard to parse, and disagree with Acee that is it clear. [ For -13 ] The draft was revised to address Alia's DISCUSS, and also Spencer's "traditional way" and "both B and P flags MUST NOT be both set" comment, but still does not expand EVPN; I also agree with Spencer that it would be helpful to expand P2P on first use. I reread the document and have some additional comments - note that these are are only comments, but I think that they would make the document more readable... 1: Introduction: "that in EVPN terminology would mean a single pair of Ethernet Segments ES(es)." - I'm confused by the 'ES(es)' - guessing this was an editing failure and 'Ethernet Segments (ES)' was intended? If not, You use both "Ethernet AD" and "Ethernet A-D" - please choose and stick with one. 1.1: Terminology: "EVI: EVPN Instance." -- Ok, but EVPN is still not defined / referenced. 3.1 EVPN Layer 2 attributes extended community " A PE that receives an update with both B and P flags set MUST treat the route as a withdrawal. If the PE receives a route with both B and P clear, it MUST treat the route as a withdrawal from the sender PE." Do the above 2 sentences say the same thing? It sure sounds like repetition, if not, please explain the difference. If not, removing one would make this less confusing. Figure 3: EVPN-VPWS Deployment Model You use the terms / labels "PSN1", "PSN2" - what are these? "Provider <something> Network"? _______________________________________________ BESS mailing list BESS@ietf.org https://www.ietf.org/mailman/listinfo/bess
