I have been selected to do a routing directorate “early” review of
draft-ietf-babel-hmac.



Document: draft-ietf-babel-hmac-00

Reviewer: Mike McBride

Review Date: 19-09-2018



Intended Status: Standards Track



Comments:



I only found a few nits. Great job with the draft, especially being a 00.
The nits that should be considered:



1.      Add a Terminology section to include HMAC, Babel, PC, etc

2.      1.1 Applicability Section: “The protocol defined in this document
assumes that all interfaces on a given link are equally trusted and share a
small set of symmetric keys (usually just one, two during key rotation).”
Consider changing it to: “…(Typically one key. Two keys during a key
rotation).” Otherwise it can read as “just one or two during key rotation”.

3.      4.2 Packet Transmission Section: “A Babel node may delay actually
sending TLVs by a small amount…”. Consider giving an example of a small
amount.



Sound reasonable?
