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
