Although SD-WAN is not a direct replacement for MPLS it does seem to get lumped in the conversation none the less. With all the SD-WAN providers saying that same message that you can reduce your circuit costs by replacing some or all of your MPLS and moving to a broadband transport. No argument here. I have even seen that in the short life-cycle of SD-WAN that there is a 2.0 version, whatever that means! I do like some of the companies that are trying not to lock you into a vendor, but by taking a more agnostic approach to it all. Which brings me to my musings, if SD-WAN is in some sense a direct replacement to MPLS, then wouldn't it stand to reason that SD-WAN providers would support what you can currently get from MPLS, which is VPLS. Layer 2 tunneling is a real need for some companies, and obviously you can't do VPLS with a broadband circuit so the solution to me is that more SD-WAN companies need to develop and support L2TPv3 to augment what VPLS is for MPLS.
