Abstract:
   As Enterprises and Service Providers upgrade their brown field or
   green field MPLS/SR core to an IPv6 transport, Multiprotocol BGP (MP-
   BGP)now plays an important role in the transition of the core as well
   as edge from IPv4 to IPv6.  Operators can now continue to support
   legacy IPv4, VPN-IPv4, and Multicast VPN-IPv4 customers.

   This document describes the critical use case and OPEX savings of
   being able to leverage the MP-BGP capability exchange usage as a pure
   transport, allowing both IPv4 and IPv6 to be carried over the same
   BGP TCP session.  By doing so, allows for the elimination of Dual
   Stacking on the PE-CE connections.  Thus making the eBGP peering
   IPv6-ONLY to now carry both IPv4 and IPv6 Network Layer Reachability
   Information (NLRI).

   This document now provides a solution for IXPs (Internet Exchange
   points) that are facing IPv4 address depletion at these peering
   points to use BGP-MP capability exchange defined in [RFC8950] to
   carry IPv4 (Network Layer Reachability Information) NLRI in an IPv6
   next hop using the [RFC5565] softwire mesh framework.
