For some reason our customers would like to have 2 seperate connections at layer 2 and want them both to be active. In this particular example they have one main fiber cable and a copper backup. We're a small ISP and I've researched some solutions like TRILL and SPB but they failed due to compatibility between vendors, Big Broadcast domain and what not!
Now i've stubmled on overlay networking solutions like EVPN (MPLS,VXLAN,NVGRE) and VPLS. But in all these design concepts (RFC's) they use a enterprise environments and assume you would like to connect LAN from location A to LAN from Location B etc. I, however want to connect the same LAN environment over a ring topology. Is this possible?
I've linked an example from a customer in the link below, I would also like to note that we control de customer equipment to some extend.
