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 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.
