I have a question if I want to make VPLS between two routers on internet,
is it must to be connect VPN(it can be EoIP) so it can transmit/receive ethernet data each other?
If it is right, VPLS/MPLS purpose is just for the centralized of network system?
I've heard about if have many routers can connect more and more as VPLS, it can be resist more and more of DDOS.
But if I had setup VPLS between two routers,
I think the performance lower than general VPN connection.
Is it right also? If it is not, please let me explain me why?
