Multipoint VPLS mapping to MEF E-TREE

Is there anyone out there who has a position on whether it is worth the effort to map Multi-root EVPL (E-TREE) atop VPLS or to await for PBB-TE and MEF to come up with somekind of a common roadmap ? F. On 2010-12-03, at 10:26 AM, Manu Chao wrote:

I have only GRT and L3VPN traffic and would like to use MPLS forwarding only for L3VPN.

Is it possible?

Thanks & Best Regards, Manu
