Of the above, VPLS.
But it really depends what you need to do. If you're selling customers
cross-town L2 services then yeah VPLS is the best option in my opinion.
If this is for use between your own equipment, other technologies
might make more sense.
I echo Roland's comment, but I'll make it more specific - stay away
from anything with spanning tree in it.
