Thank you, Scott and all of you for your answers and time.
From my understanding M-Ethernet is a some kind of service.
Standartized technology that allows to connect multiple different
networks. And it is independent from physical and datalink layers. And
nowadays which tecnology is the most used(VPLS or Metro)? What about
MPLS? Sorry I'm a little confused. I really want to understand.
