This is a routing directorate review. Just like other directorate review, it should be considered as part of the last call comments by the authors, the WG shepherd, and the AD. 

Status: no editorial or textual comments. 
The changes from "master-slave" relationship to a "leader-follower" provide an excellent recontextualization of the concepts.   The text is easy to read.  As the document stands, I have to no additional comments.
