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

[Kalyani Rajaraman <[e-mail]>]

Hi Susan,

We at Arrcus have implemented BGP-CAR and tested interop with Cisco. I
support BGP-CAR versus BGP-CT.  BGP-CAR can be extendable to other
transports like SRv6 whereas BGP-CT is MPLS focussed.

1. Do you agree or disagree that these two drafts are functionally
identical?

        Functionally similar but there are implementation differences.



2. If you agree, should we have just one draft or do the operational
difference encourage us to have two drafts?

      One draft.

3. If you disagree, do the functional differences encourage us to have one
or two drafts adopted?

     I  recommend  the  BGP-CAR draft to be adopted.


Thanks,

Kalyani
