Hello

I have been selected to do a routing directorate “early” review of this draft.
https://datatracker.ietf.org/doc/draft-ietf-mpls-rfc3107bis/

The routing directorate will, on request from the working group chair, perform an “early” review of a draft before it is submitted for publication to the IESG. The early review can be performed at any time during the draft’s lifetime as a working group document. The purpose of the early review depends on the stage that the document has reached.

For more information about the Routing Directorate, please see https://wiki.ietf.org/en/group/rtg/RtgDir

Document: draft-ietf-idr-bgp-car-02
Reviewer: Ben Niven-Jenkins
Review Date: 31 July 2023
Intended Status: Experimental

Summary:
I have some minor concerns about this document that I think should be resolved before it is submitted to the IESG.

Comments:
The document provides lots of details in the main sections and examples in the appendices. I think that is generally ready to be published. The only suggestion I would have is to provide a short overview introducing BGP CAR and color aware routing before leaping into terminology and the details of the BGP CAR SAFI. Expanding the introduction section with an extra paragraph or two would be sufficient.

Thanks
Ben
