Abstract:

   This document describes a BGP based routing solution to establish
   end-to-end intent-aware paths across a multi-domain transport
   network.  The transport network can span multiple service provider
   and customer network domains.  The BGP intent-aware paths can be used
   to steer traffic flows for service routes that need a specific
   intent.  This solution is called BGP Color-Aware Routing (BGP CAR).

   This document describes the routing framework and BGP extensions to
   enable intent-aware routing using the BGP CAR solution.  The solution
   defines two new BGP SAFIs (BGP CAR SAFI and BGP VPN CAR SAFI) for
   IPv4 and IPv6.  It also defines an extensible NLRI model for both
   SAFIs that allow multiple NLRI types to be defined for different use
   cases.  Each type of NLRI contains key and TLV based non-key fields
   for efficient encoding of different per-prefix information.  This
   specification defines two NLRI types, Color-Aware Route NLRI and IP
   Prefix NLRI.  It defines non-key TLV types for MPLS label stack,
   Label Index and SRv6 SIDs.  This solution also defines a new Local
   Color Mapping (LCM) Extended Community.
