Backgrounds
▪ E-Tree Requirements in multiple SDOs
• Non-standard mechanism for single root topology
• Single VSI + extended split horizon mechanism
• No VPLS support for multi-roots topology
• Multiple nodes with root & leaf attached in a single domain • Multiple roots and leaves located diversely across multiple

✓ No change to VPLS architecture and PW layer semantics, standard work can be minimized
✓ Scalability with only a single VSI and a single suite of PWs needed
