    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 (PBB-)EVPN and how (PBB-)EVPN offers a more efficient implementation of these functions.},
