Hi Yimin,

    Thank you very much for your suggestions/comments.
    I will add reference RFC 8679 with some texts into the draft.

Best Regards,
Huaimo

Hi authors,



I’d like to suggest this draft to reference RFC 8679.



In particular, RFC 8679 as a generic EP framework with a lot of general discussions (see the points below), which are applicable to both MPLS and IPv6 data plane, and all types of transport tunnels. However, this draft seems to have almost no consideration or discussion on these topics. I don’t think the draft needs to repeat these discussions, but I suggest to add a section(s) to discuss these points generally by referencing RFC 8679.



  *   general scope and requirements
  *   transport layer failure/protection vs. service layer failure/protection
  *   applicability
  *   failure detection mechanisms
  *   egress node protection
  *   egress link protection
  *   relationship between EP and global repair
  *   co-existing of different types of transport tunnels and bypass tunnels
  *   security





Thanks,



-- Yimin Shen
