Hi Steiner,

 

I agree L2VPN does have a market [forgive the sarcasm but so does poison :)].

 

The point I do not quite get is why would the end user want a termination point on a Packet switching device with the SP?

 

Are you saying that the cost difference between buying a Layer 2 switch versus a Layer 3 switch is "so highly significant"?

 

Why would he not buy a Layer 3 switch (if what he wants is ethernet) , take a link and connect it off to the SDH/SONET multiplexer provided by the SP and use the same? What is the benefit he gets by terminating at a Packet switching kind of device on the SP end?
