Dear WG, From a hardware perspective, the SRv6 Locator allocation via DHCPv6 extensions primarily impacts the control plane and system software stack, while the data plane forwarding requirements remain aligned with standard SRv6 packet processing capabilities. Our network chips already provide comprehensive SRv6 SID support, including Locator-based forwarding, which forms the foundation for this DHCPv6-based dynamic allocation mechanism.
The document has been thoroughly reviewed from an implementation standpoint. The proposed DHCPv6 extensions for SRv6 Locator distribution represent a significant improvement in network automation and scalability, particularly for CPE deployments where manual SRv6 configuration becomes operationally challenging. The hardware forwarding performance remains unaffected, as the dynamic Locator assignment operates entirely within the control plane. I support progressing this draft to publication from the perspective of a network chip vendor. This standardization effort addresses a critical operational need in SRv6 network deployments and we recommend its advancement.

Draft link：https://www.ietf.org/archive/id/draft-ietf-spring-dhc-distribute-srv6-locator-dhcp-08.html This revision addresses all comments received to date, and we believe the document is now ready for Working Group Last Call (WGLC). We would like to express our sincere appreciation to Nick for agreeing to serve as the document shepherd. Backgroud of the draft: - Proposes a mechanism for SRv6 locator assignment to Segment Endpoint Nodes via DHCPv6, applicable within trusted domains. - Successfully implemented by H3C and Raisecom. - Validated through field testing by China Mobile, confirming full functional and interoperability compliance with requirements. Request for Feedback To facilitate comprehensive alignment with the broader SPRING and DHC WGs, we kindly request feedback on the following aspects: - Further Technical Review - Use Case Expansion, such as: Are there additional deployment scenarios that should be explicitly addressed? - Any other editorial or technical suggestions to improve clarity and interoperability. Best regards, Weiqiang Cheng On behalf of the co-authors
