[f-nsp] Question about MLX/XMR capabilities

[Allan Eising]

Ouch, that's a big show-stopper for me.

I've heard a rumor that vlan overlap was possible with MPLS... I guess this
is not the case then.

Thank you for your swift answers, although I'm saddened by the result, but
that's not your fault :)
