Hi Thomas, I've read the draft and have some questions. 1) RFC 9160 introduces new protocol types for SR-MPLS top label. Considering that the MPLS top label is always the label to be processed, the user can know which protocol the SR-MPLS SID to be processed is learned from. But this draft describes the routing protocol where the last SRv6 segment has been learned from, instead of the SRv6 segment to be processed by the current hop. As for my understanding, the current draft is inconsistent with RFC 9160 in this aspect.
2) Related to point 1，in SR-MPLS, exporting the top label can provide the information of the segment to be processed, but in SRv6, segment list and segments left(currently not defined in the draft) are both needed to provide the similar information. 2) Element for SRH TLV is not defined in the draft, what's the consideration about that?

The document aims to be on par with MPLS-SR. Describe the routing protocol or PCEP extension where the last SRv6 segment has been learned from, the SRv6 segment list and all other properties from the Segment Routing header. I would appreciate your document review and feedback. I aim to present at IETF 113 at OPSAWG and SPRING and request adoption at OPSAWG.
