Hi Minxue,
v-03 looks well-structured, and the technical content is clearly presented.
I have a few non-blocking comments after reading it:
1) About security considerations, I suggest adding a description of what would
happen if an End.IL SID is maliciously injected or tampered with in the SRH.
For example, an attacker could redirect traffic to an unintended underlay
connection.
2) Section 3 specifies that the underlay network connection "SHOULD" be
established before the associated End.IL SID is announced into the network. It
may be useful to clarify whether it also supports the SID being advertised
before the underlay connection is set up. If this mode is not supported, would
it be more appropriate to use "MUST" instead of "SHOULD" to avoid ambiguity?
3) Editorial nits
In Section 4.2, "In addition, For some type of services" – the "For" should be
lowercase ("for").
In Section 8.4, "performend" should be "performed".
Given that this work has been implemented by multiple vendors and verified
through interoperability testing, I believe this work is ready for continued
progress.
Best regards,
Yao

Dear WG,
We are sharing an updated version of
draft-ietf-spring-srv6-inter-layer-programming (revision -03) for your review
and feedback.
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.
Best regards,
Minxue (on behalf of coauthors)

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
