Document: draft-ietf-lisp-vendor-lcaf-09 Reviewer: Christer Holmberg Review Date: 2022-04-11 IETF LC End Date: 2022-04-12 IESG Telechat date: Not scheduled for a telechat Summary: The document is well written, and easy to read and understand. However, I do have a couple of issues. Major issues: Q1: I do wonder why the document is published as Experimental, however, due to the following reasons: a) The document defines usage of the Type value 255. b) Section 3 says: "If a LISP device receives a LISP message containing a Vendor Specific LCAF with an OUI that it does not understand, it MUST drop the message and it SHOULD create a log message." This sounds like an update to LISP. c) Section 3 defines new header fields. Minor issues: N/A Nits/editorial comments: Q2: Section 1 says: “The Vendor Specific LCAF allows organizations to create LCAF addresses to be used only internally on particular LISP deployments.” Is “allows” the best wording? Where organizations previously disallowed to do this? Would it be more correct to say “defines how organizations can create…”?
