Both of them have been implemented and deployed. Of course, each has its own flaw. The former has no protocol type field (https://www.ietf.org/mail-archive/web/nvo3/current/msg01520.html) and the latter' ECMP capability is not good enough. Xiaohu, A minor nit is that it was the Independent Stream Editor at the RFC Editor who published these documents, not the IETF. In most cases that doesn't make a difference. Regards, Erik > > If the NVo3 WG still wants to publish some RFCs on NVo3 data plane encapsulation, it seems reasonable to build on the above two approaches and fix their flaws accordingly. VXLAN-GPE is designed to fix the flaw of VXLAN although whether or not to use a different port number than VXLAN's port number is still controversial. Personally, I prefer to the approach as defined in (https://tools.ietf.org/html/draft-yong-l3vpn-nvgre-vxlan-encap-03#page-3) since it seem much simpler than the current approach as defined in (https://tools.ietf.org/html/draft-quinn-vxlan-gpe-03#page-8). GRE-in-UDP is a very good choice to fix the flow of NVGRE. > > Best regards, > Xiaohu > >> -----Original Message----- >> From: nvo3 [mailto:nvo3-bounces@ietf.org] On Behalf Of Black, David >> Sent: Friday, July 15, 2016 2:42 AM >> To: Manish Kumar (manishkr); NVO3 >> Subject: Re: [nvo3] Mail regarding NVO3 data plane drafts >> >>> I believe GRE(+UDP) deserves a discussion as well. >> FYI - over in TSVWG, this GRE/UDP draft is standards track and has completed >> WG Last Call: >> https://datatracker.ietf.org/doc/draft-ietf-tsvwg-gre-in-udp-encap/ >> Thanks, --David >> >>> -----Original Message----- >>> From: nvo3 [mailto:nvo3-bounces@ietf.org] On Behalf Of Manish Kumar >>> (manishkr) >>> Sent: Thursday, July 14, 2016 12:54 PM >>> To: Bocci, Matthew (Nokia - GB); NVO3 >>> Subject: Re: [nvo3] Mail regarding NVO3 data plane drafts >>> >>> Hi Matthew, >>> >>> I agree this is an important aspect that’s just lingering around. >>> Although not being adopted and not a part of the WG, if there is a >>> discussion on pros-cons/merits- demerits, I believe GRE(+UDP) deserves >>> a discussion as well.
