Alexey Melnikov has entered the following ballot position for draft-ietf-lisp-rfc6833bis-16: Discuss When responding, please keep the subject line intact and reply to all email addresses included in the To and CC lines. (Feel free to cut this introductory paragraph, however.) Please refer to https://www.ietf.org/iesg/statement/discuss-criteria.html for more information about IESG DISCUSS and COMMENT positions. The document, along with other ballot positions, can be found here: https://datatracker.ietf.org/doc/draft-ietf-lisp-rfc6833bis/ ---------------------------------------------------------------------- DISCUSS: ---------------------------------------------------------------------- I have a list of smaller points that should be relatively easy to address. The two main ones: I believe [I-D.ietf-lisp-sec] needs to be a Normative Reference for this document. This will address some of the issues raised by Benjamin, but will also make description of various security bits meaningful. Similarly, in Section 5.6: I: This is the xTR-ID bit. When this bit is set, what is appended to the Map-Register is a 128-bit xTR router-ID and then a 64-bit site-ID. See LISP NAT-Traversal procedures in [I-D.ermagan-lisp-nat-traversal] for details. This description makes [I-D.ermagan-lisp-nat-traversal] a normative reference. ---------------------------------------------------------------------- COMMENT: ---------------------------------------------------------------------- Abstract By using this Control-Plane service interface and communicating with Map-Resolvers and Map-Servers, LISP Ingress Tunnel Routers (ITRs) and Egress Tunnel Routers (ETRs) are not dependent on the details of mapping database systems, which facilitates modularity with different database designs. Since these devices implement the "edge" of the LISP Control-Plane infrastructure, connect directly to LISP-capable Internet end sites, and comprising the bulk of LISP-speaking devices, reducing their implementation and operational complexity should also reduce the overall cost and effort of deploying LISP. The last sentence: I've reread it several times and still not sure what it says. I suggest rewording, possibly breaking up into shorter sentences. In Section 5.1 the acronym SMR is used before it is defined (It is defined on the next page). In 5.2: A: This is an authoritative bit, which is set to 0 for UDP-based Map- Requests sent by an ITR. It is set to 1 when an ITR wants the destination site to return the Map-Reply rather than the mapping database system. This sentence seems to be missing a word at the end, because you don't return "the mapping database system". In Section 5.6: T: This is the use-TTL for timeout bit. When set to 1, the xTR wants the Map-Server to time out registrations based on the value in the "Record TTL" field of this message. And what happens when it is 0? 11.4. LISP Address Type Codes Therefore, there is no longer a need for the "LISP Address Type Codes" registry requested by [RFC6830]. This document requests to remove it. IANA registries are not supposed to be removed, they typically declared closed when not needed. Can you elaborate of whether this registry was ever used?
