Hi Ran, The questions/points raised by Sasha, et all on the thread below also applies to this draft that you have brought up - i.e. how things work when this is modeled as a L1 interface and why not L3. https://mailarchive.ietf.org/arch/msg/spring/IrzGONQP1zXvBHkvmZyaHOEwC68/ Additionally, I am not familiar with the concept of "channel" used here and specifically what standard covers that. Would be good if you can elaborate. Otherwise, the draft-dong and draft-han are similar with the main difference being that one is proposing a variant of End.X while the other is End.B (BSID). On a side note (but important one), I am concerned when you said that this proposal has been implemented by ZTE but I find no allocation made for the code point. Please do not squat - especially in this case where the registry is FCFS: https://www.iana.org/assignments/segment-routing/segment-routing.xhtml#srv6-endpoint-behaviors Thanks, Ketan On Wed, Nov 9, 2022 at 1:21 PM <chen.ran@zte.com.cn> wrote: > Hi Joel，Sasha，Ketan and WG > > > There is a similar proposal ， and in which we want to provide the > end-to-end SRv6 tunnel to bind the L1 connection directly.
