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?
