Hello Zhenqiang Li,

Thanks for your review and comments. Please check inline below.

Subject: Re: [Lsr] WG Adoption Call for draft-li-lsr-ospfv3-srv6-extensions

support the adoption with the following comments.

1. What does SRH stack mean in section 4.2? AS specified in RFC8200 and draft-ietf-6man-segment-routing-header, only one SRH can be presented in one IPv6 header.

[KT] Thanks for catching this error and will fix as below:


OLD: The Maximum End Pop MSD Type specifies the maximum number of SIDs in
   the top SRH in an SRH stack to which the router can apply Penultimate
   Segment Pop (PSP) or Ultimate Segment Pop (USP)


NEW: The Maximum End Pop MSD Type specifies the maximum number of SIDs in

   the SRH for which the router can apply Penultimate

   Segment Pop (PSP) or Ultimate Segment Pop (USP)

2. The abbreviations used in this draft should be listed in a seperated section or point out where they are defined.
[KT] We've followed the convention of expanding on first use as also providing reference where necessary. Please do let know if we've missed doing so anywhere.

3. Algorithm field is defined for End.x SID to carry the algorithm the end.x sid associates. But no algorithm field is defined for End SID in section 7. May I know the reason?
[KT] The SRv6 Locator TLV that is the parent of the SRv6 End SID Sub-TLV carries the algorithm and hence there is no need to repeat in the Sub-TLV. This is not the case for SRv6 End.X SID Sub-TLV and hence it has the algorithm field.

Thanks,
Ketan

Best Regards,
Zhenqiang Li
