Also known as Ethernet over MPLS (EoMPLS). Main difference from VPLS is in its nature of being point to point only.

Reminder network topology concept for future. The point of the concept is to use P2P links to create a star topology with the equipment that doesn’t have VPLS functionality. I didn’t check if it works at all but why not give it a try:
