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 an edge from IPv4 to IPv6.  Operators can now continue to support
   the legacy IPv4, Virtual Private Network (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
   (Border Gateway Protocol) BGP TCP session.  By doing so, provides for
   the elimination of Dual Stacking on the Provider Edge - Customer Edge
   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 Internet Exchange Point
   (IXP) 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.
