        BGP Signaling of IPv6-Segment-Routing-based VPN Networks
                    draft-dawra-idr-srv6-vpn-02.txt

Abstract

   This draft defines procedures and messages for BGP SRv6-based L3VPN
   and EVPN.  It builds on RFC4364 "BGP/MPLS IP Virtual Private Networks
   (VPNs)" and "RFC7432 "BGP MPLS-Based Ethernet VPN" and provides a
   migration path from MPLS-based VPNs to SRv6 based VPNs.
