The early review can be performed at any time during the draft’s lifetime as a working group document. For more information about the Routing Directorate, please see http://trac.tools.ietf.org/area/rtg/trac/wiki/RtgDir<http://trac.tools.ietf.org/area/rtg/trac/wiki/RtgDir> Document: draft-ietf-ospf-segment-routing-msd.txt Reviewer: Tal Mizrahi Review Date: April 2018 Intended Status: Standards Track Summary: This document is basically ready for publication, but has a couple of issues and a few nits that should be considered prior to being submitted to the IESG. Comments: · The Security Considerations should be more detailed. The reference to RFC 7770 is a good start, but please add more details about potential attacks. For example, what happens if there is a spoofed MSD with a low MSD value? What is the impact of such an attack? · Section 3: o The description of the Length field says “minimum of 2”, implying it can be higher than 2. On the other hand, the Value field: “consists of a 1 octet sub-type (IANA Registry) and 1 octet value.”, which implies that the Length is equal to 2. Please align the two descriptions, i.e., if flexibility for future sub-types is required, please change the description of Value to allow longer values. o The comment applies to Section 4 as well. Nits: · The term “minimum MSD”, which translates to “minimum maximum SID Depth” should be explained. · The term “maximum MSD” appears twice in the document, which seems either redundant, or a typo (did you mean minimum MSD?). · The acronym SID should be spelled out on its first use. · The acronyms RI and LSA should be added to the Terminology subsection. · Section 1.1.1 and Section 2 are both titled “Terminology”. It would be best to merge Section 1.1 into Section 2, and avoid the duplicate title. · “each node/link a given SR path” -> “each node/link of a given SR path” · “nodes and links which has been configured” -> “nodes and links that have been configured” · “laso”->”also” · “Other Sub-types other than defined” -> “Sub-types other than defined” Cheers, Tal Mizrahi.
