Hi Minxue and WG,
I have read the document and I believe this work is ready for continued progress. The End.IL behavior of this document extends SRv6 programming into the underlay, enabling differentiated carriage and deterministic low latency by leveraging underlying transport capabilities. This approach has been validated in live network deployments with multi‑vendor interoperability. Given its practical value and maturity, I encourage the WG to move this document forward.

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: 2026-08-11Abstract: 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.The IETF datatracker status page for this Internet-Draft is:https://datatracker.ietf.org/doc/draft-ietf-spring-srv6-inter-layer-programming/There is also an HTMLized version available at:https://datatracker.ietf.org/doc/html/draft-ietf-spring-srv6-inter-layer-programming-03A diff from the previous version is available at:https://author-tools.ietf.org/iddiff?url2=draft-ietf-spring-srv6-inter-layer-programming-03Internet-Drafts are also available by rsync at:rsync.ietf.org::internet-drafts_______________________________________________spring mailing list -- [email protected] unsubscribe send an email to [email protected]
