Same here, Pat. There is no anti-mesh-under intention. From the L3 perspective the mesh under looks like one hop and we must cover that case, certainly!

We already have requirements that apply to one L3 hop like the capability to proxy on the backbone, but nothing that is specific to a multi L2 hops mesh under.

If you are aware of requirements that we missed please let us know... Now is the time !
