Abstract:

   This document describes a mechanism to advertise IPv6 prefixes in BGP
   which are associated with Color Extended Communities to establish
   end-to-end intent-aware paths for SRv6 services.  Such IPv6 prefixes
   are called "Colored Prefixes", and this mechanism is called Colored
   Prefix Routing (CPR).  In SRv6 networks, the Colored prefixes are the
   SRv6 locators associated with different intent.  SRv6 services (e.g.
   SRv6 VPN services) with specific intent could be assigned with SRv6
   SIDs under the corresponding SRv6 locators, which are advertised as
   Colored prefixes.  This allows the SRv6 service traffic to be steered
   into end-to-end intent-aware paths simply based on the longest prefix
   matching of SRv6 Service SIDs to the Colored prefixes.  In data
   plane, dedicated transport label or SID for the inter-domain path is
   not needed, thus the encapsulation efficiency could be optimized.
   The existing IPv6 Address Family could be used for the advertisement
   of IPv6 Colored prefixes, thus this mechanism is easy to interoperate
   and can be deployed incrementally in multi-domain networks.
