    abstract =  {This document proposes a simple and effective approach to emulate E-Tree services over an MPLS network. Section 4 presents a minimal extension to the current VPLS architecture defined in {[}RFC4761{]} and {[}RFC4762{]} to fulfil the specific E-Tree requirement: Leaf cannot communicate with Leaf. Backward compatibility issues are addressed also.},
