Some ISPs sell (very expensive) 'ethernet' links into your shop. Is this just FTTP but with L2 shipped over the link not just IPv4/IPv6?
A&A for example sells it and it is eye-wateringly expensive iirc.
Q: I don't understand it as where is the ethernet supposed to come from? And you arrange to get IP at the far end onto it?
Is it also used for site-to-site bridging? Nice if you have stuff like really really old windows boxes that do not necessarily interwork with peers over IP and a routed n/w.
I suppose there is the idea that you could run arbitrary types of L3 protocols over it, not just IP, as well as L2 traffic, without the overheads of tunnels.
