We use MPLS for this. We can have as many as 6 paths coming out of a 
single Metro-E node. MPLS will handle it just fine.

Any Layer 2 option won't work the way you want it... they are simply not 
built for that level of redundancy or load balancing.

We have not tried to do this with VXLAN, and don't intend to.
