Moin!

I am an assigned INT directorate reviewer for draft-ietf-rift-applicability.

These comments were written primarily for the benefit of the Internet Area Directors. Document editors and shepherd(s) should treat these comments just like they would treat comments from any other IETF contributors and resolve them along with any other Last Call comments that have been received. For more details on the INT Directorate, see https://datatracker.ietf.org/group/intdir/about/

This document does a good job explaining when RIFT can be used and how it should be used in certain scenarios. The examples, especially the operational considerations are understandable and describe applicable cases. There is a steep learinig curve though with a lot of field (Date Center architecture and routing) specific acronnyms used which while at least name expanded and somtimed document referenced require a lot of external reading for a non field aware reader, to fully understand the document. If the addressees of this document are technical experts in the field as the intro to section 3 suggest, then this is fine, however if the audience is more general IETF audience some more introductionary explanation of these architectures and terms instead of referring to external documents would be benefical.

So long
