Hi Nurit,

In the L2VPN WG meeting held in this morning, when commenting about "Requirements for MEF E-Tree Support in VPLS", you had some doubts in the following requirement "Ethernet Broadcast/Multicast from Leaf to Roots".

I believe this is covered in Sec. 6.1.2.2 of MEF 10.2 (http://metroethernetforum.org/PDF_Documents/technical-specifications/MEF10.2.pdf):
"An ingress Service Frame mapped to the EVC at a Leaf UNI MUST NOT result in an egress Service Frame at another Leaf UNI but MAY result in an egress Service Frame at some or all of the Root UNIs."
