        BGP Signaling of IPv6-Segment-Routing-based VPN Networks
                    draft-dawra-idr-srv6-vpn-00.txt

Abstract

   This draft defines procedures and messages for BGP SRv6-based EVPNs
   and L3 VPNs.  It builds on RFC7432 "BGP MPLS-Based Ethernet VPN" and
   RFC4364 "BGP/MPLS IP Virtual Private Networks (VPNs)" to provide a
   migration path from MPLS-based VPNs to SRv6 based VPNs.
