Dear all, From my perspective as a contributor, I would like to thank Minxue and the authors for the updates in revision -03.
Based on the multi-vendor interoperability experience, I believe the newly added Operational Considerations section provides valuable guidance for operator deployment. Furthermore, the registration requests for REPLACE-CSID and NEXT-CSID flavors in the IANA section enable End.IL to fully support SRH compression mechanisms, while the additional combinations of two flavors (e.g., PSP & USP, PSP & USD, USP & USD) offer more flexible deployment options. These enhancements are valuable for various inter-layer scenarios where fine-grained packet overhead control is required. I support the current technical direction of the draft. Thanks.

This draft describes the SRv6 End.IL behavior, which steers packets to underlay connections to achieve efficient inter-layer coordination. The draft was presented at both the Hackathon and WG session at IETF 125. Based on feedback, we have made the following updates: 1. An Operational Considerations section is added, and the information of implementations and interoperability test among multiple vendors is documented. 2. Two contributors are added based on their contributions to the implementation and interoperability test. 3. In the IANA section, the registration requests for End.IL behavior with different CSID flavors is added. We would appreciate your review and comments on the list. Thank you for your time and consideration.

Title: SRv6 for Inter-Layer Network Programming Authors: Liuyan Han Jie Dong Minxue Wang Ran Chen Zongpeng Du Name: draft-ietf-spring-srv6-inter-layer-programming-03.txt Pages: 16 Dates: 2026-08-11 Abstract: The Segment Routing over IPv6 (SRv6) Network Programming framework enables a network operator or an application to specify a packet processing program by encoding a sequence of instructions in the IPv6 packet header. Following the SRv6 Network Programming concept, this document defines SRv6 based mechanisms for inter-layer network programming, which can help to integrate the packet network layer with its underlying layers efficiently. For inter-layer path programming, a new SRv6 behavior is defined for steering packets to underlay network connections. The applicability of this new SRv6 behavior in typical scenarios is illustrated.
