Identify L2 control protocols which will require transparent tunneling end to end before making a decision on underlay tech. Beware of multiple vendor handoffs / NNIs under the hood of any solution, but especially an "oMPLS" solution.

Still using mpls/vpls occasionally… oob mgmt backhaul. For DC interconnect, I use evpn/mpls, since I have an mpls network. We are an SP, so mpls has been the basis for our network-based-L2/L3 VPN’s for 10 years or so.
