   A generic VPLS solution for E-Tree services is proposed which uses
   VLANs to indicate root/leaf traffic. A VPLS Provider Edge (PE) model
   is illustrated as an example for the solution. In the solution, E-
   Tree VPLS PEs are interconnected by  PWs which carry the VLAN
   indicating the E-Tree attribute, the MAC address based Ethernet
   forwarding engine and the PW work in the same way as before. A
   signaling mechanism for E-Tree capability and VLAN mapping
   negotiation is further described.
