                   E-TREE Support in EVPN & PBB-EVPN
                   draft-sajassi-l2vpn-evpn-etree-02

Abstract

   The Metro Ethernet Forum (MEF) has defined a rooted-multipoint
   Ethernet service known as Ethernet Tree (E-Tree).  [ETREE-FMWK]
   proposes a solution framework for supporting this service in MPLS
   networks. This document discusses how those functional requirements
   can be easily met with EVPN.
