Re: [Idr] Part 2 of CAR/CT Adoption call (7/6 to 7/20) - Adoption of draft-dskc-bess-bgp-car-05.txt and draft-kaliraj-idr-bgp-classful-transport-planes-17.txt

[Satoru Matsushima <[e-mail]>]

Hi Chairs, IDR,

Many of people already mentioned with different words, but  let me provide
my comments on the questions as an operator:

1. Disagree on that these two drafts are identical since color exists in
the NLRI key part or not is fundamentally different for basic path
selection.
2. n/a
3. One draft should be adopted with existing policy enhancement to keep the
same path selection key, and thereby CAR should be adopted.

Best regards,
--satoru
