Document: draft-ietf-opsawg-ac-lxsm-lxnm-glue-11 Reviewer: Reese Enghardt Review Date: 2024-12-06 IETF LC End Date: 2024-12-09 IESG Telechat date: Not scheduled for a telechat Summary: The document is fairly clear and concise. I have a few clarification questions and suggestions to make the document more accessible. Major issues: None. Minor issues: Section 1: Please consider a sentence to explain the high-level motivation for this document. Is it to allow VPNs to be modeled as Attachment Circuits (ACs), where ACs are means to attach routers to other routers or end systems? Section 2: Even though the term "Attachment Circuit" is defined in the referenced draft I-D.ietf-opsawg-teas-attachment-circuit, please consider providing the definition in this document, as it appears fundamental to understanding the document. Section 4.1: As Section 4 is titled "Sample Uses of the Data Models", and this document is about VPNs, I expected an example that mentions VPNs, but I didn't see any explicit mention of a VPN in this section. Could any of the ACs presented in this example be used to host a VPN, if defined using the data model introduced in this draft? Please consider adding a brief explanation of how does the data model introduced in this draft relates to the example. Section 4.2: "Customers can request a bearer ("ietf-bearer-svc") or an attachment circuit ("ietf-ac-svc") to be put in place, and then refer to that bearer or AC when requesting VPN services that are bound to the bearer or AC ("ietf-ac-glue")." From this text, it sounds like bearer or AC are interchangeable, yet, according to Section 3, ietf-ac-gue does not reference ietf-bearer-svc. In the model itself, I see that the title of ietf-ac-svc mentions both Bearer and ACs. So, is it still necessary to reference ietf-bearer-svc in this section? Nits/editorial comments: None.
