                    draft-ietf-bess-srv6-services-01

Abstract

   This draft defines procedures and messages for SRv6-based BGP
   services including L3VPN, EVPN and Internet services.  It builds on
   RFC4364 "BGP/MPLS IP Virtual Private Networks (VPNs)" and RFC7432
   "BGP MPLS-Based Ethernet VPN".
