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.}, }
