Re: [Idr] [RTG-DIR] Rtgdir early review of draft-ietf-idr-bgp-car-02

["Dhananjaya Rao (dhrao)" <[e-mail]>]

Hello Ben,

We have made a couple of updates to the CAR draft (latest is -04), as part of which we’ve also provided more context in the introduction.
Could you please take a look when you get a chance and let us know if things are clear enough ?
Apologies for the long delay in responding. Thank you once again for your review.

Regards,
-Dhananjaya

Ben:

Can you provide additional detail regarding your concerns?

Sure. The Introduction is only 4 lines before the document starts defining terminology and the section after that (1.2 illustration) assumes pre-knowledge of what Color-Aware Routing is.

As someone without any pre-knowledge of color-aware routing or intent-aware paths it was quite difficult to form an idea in my head of what the big picture into which BGP CAR fits is.

I am suggesting including some additional introductory text that provides a bit of background and context and how BGP CAR fits into the bigger picture before the document starts getting into the gritty details of BGP CAR.

You state:

“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.”

Hello

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

Of course I meant https://datatracker.ietf.org/doc/draft-ietf-idr-bgp-car/ :-)

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

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
