Document: draft-ietf-homenet-babel-profile-05 Reviewer: Stewart Bryant Review Date: 2018-02-20 IETF LC End Date: 2018-02-26 IESG Telechat date: Not scheduled for a telechat Summary: This is understandable, and close to completion. There are a few minor points that need attention, and couple of major points that may just need clarification. Major issues: In addition, if implementations use conflicting route selection policies, persistent oscillations might occur. SB> Is this consistent with the statement earlier in the para that SB> " Distinct SB> implementations of RFC 6126bis Babel will interoperate, in the SB> sense that they will maintain a set of loop-free forwarding paths"? ======= Since IPv6 has some features that make implementations somewhat simpler and more reliable (notably link-local addresses), we require carrying control data over IPv6. SB> Earlier you said that IPv4 also had Link Local addresses, so how SB> can link local addresses be the deciding selection criteria? Is there SB> something technically better about IPv6 LL? Minor issues: Rationale: support for wireless transit links is a "killer feature" of Homenet, something that is requested by our users and easy to explain to our bosses. In the absence of dynamically SB> Not sure explicability to your boss counts for much as a basis for SB> a feature an international standard. ====== Nits/editorial comments: Abstract This document defines the subset of the Babel routing protocol and its extensions that a Homenet router must implement, as well as the interactions between HNCP and Babel. SB> HNCP needs to be expanded SB> Both need a reference, but the reference needs to be expanded SB> i.e. RFC7788 not [RFC7788] ===== The core of the Homenet protocol suite consists of HNCP [RFC7788], a SB> HNCP needs to be expanded on first use =====
