Jeff,

	This effort is clearly needed to provide a consistent interworking solution. 

Thanks,

[Speaking as an individual contributor]

Working Group,

For your consideration, a draft discussing some possible interop procedures for BGP-CAR/BGP-CT.

The focus of the draft is on mapping for forwarding state along with what it takes to map NLRI keys from one mechanism to another.

Two items notably absent or incomplete are procedures for SRv6 forwarding and for VPN-CAR.  The BGP-CT authors have indicated in recent threads that they're considering different procedures for that encapsulation.  Also, the BGP-CT authors haven't addressed the VPN-CAR use case at this point in their document.

        Title           : Interoperability Procedures for BGP Routes with Color
        Author          : Jeffrey Haas
  Filename        : draft-haas-idr-bgp-diffract-00.txt
  Pages           : 19

Abstract:
   "BGP Routes with Color" have become a topic of interest in the IDR
   Working Group.  The authors of the various proposals have many things
   in mind to solve with them, how a color might be used, and the
   operational model for their solution.  In general, the solutions
   share some core properties: Routes for an IP endpoint, that have a
   domain-wide semantic element to differentiate forwarding (often
   called a color), and appropriate state to enable that differentiated
   forwarding.

   Examples of the technologies enabling differentiated forwarding
   include MPLS and Segment Routing.

   This document examines two of the current proposals - BGP Color-Aware
   Routing, and BGP Classful Transport - and proposes mechanisms to
   permit them to interoperate.
