Hi Pablo, Great!! Thank you for solving my confusion. It confuses me a long time.
It is very happy to know I am correct. Haha. Thanks, Cheng From: Pablo Camarillo (pcamaril) [mailto:[email protected]] Sent: Wednesday, March 06, 2019 5:27 PM To: Chengli (Cheng Li) <[email protected]> Cc: [email protected]; Lizhenbin <[email protected]> Subject: Re: draft-filsfils-spring-srv6-network-programming Hi Cheng, Thanks for the support. In reply to your questions: 1.- Alignment with the latest SRH draft. 2.- The End, End.X or End.T behaviors cannot be the last SID of the SID list unless combined with the USD flavor (or USP) in which case they can be the last SID. I will review the text and make the editorial changes if needed to make sure this is clear (your last sentence). Thanks, Pablo.

The content of these drafts has been stable for a while, I think they are ready to progress. I have some comments regarding to PSP, USP and USD flavors in draft-filsfils-spring-srv6-network-programming-07. 1: What is the motivation for introducing the USD flavor? With USD, then the END, END.T and END.X can be the last SID? 2: In section-4.1<https://tools.ietf.org/html/draft-filsfils-spring-srv6-network-programming-06#section-4.1> , 4.2 and 4.3, the document says that End, End.X, End.T can not be the last SID of SID list. But in section-4.21.2<https://tools.ietf.org/html/draft-filsfils-spring-srv6-network-programming-06#section-4.21.2>, the End, End.X, and End.T can be the last SID when there is another SRH following. Even, in that case, the last SID of the SID list MUST be SID of End, End.X, and End.T, correct? If End, End.X, End.T can not be the last SID of SID list, then USP of End, End.X, End.T can not work. So I think the text should be: End, End.X, and End.T SID can be the last SID if (1) it has USD flavor or (2) it has USP flavor while there is another SRH following it.

There are several minor updates to the document, mainly addressing ICMP and having better alignment with SRH draft. Also, based on WG feedback, we have split the document moving the illustrations into a new informational draft. As always, any feedback or question is more than welcome. https://datatracker.ietf.org/doc/draft-filsfils-spring-srv6-network-programming/ https://datatracker.ietf.org/doc/draft-filsfils-spring-srv6-net-pgm-illustration/ We believe that the content of both drafts is mature and has been stable since the first revision in March 2017. We are tracking several opensource and vendor proprietary implementations. Some of these have actually participated in a public interop more than a year ago. For these reasons we believe that both documents are ready to progress and be adopted by the working group. Thanks, Pablo (on behalf of authors&contributors)
