[c-nsp] Transparent LAN over Layer3

[Michael K. Smith]

Hello Paul:

If you control the L2 transport all the way from each of the clients' sites
then you could just us Q-in-Q trunking.  The next level up would be VPLS at
Layer 2 with isolated L2 domains on the same fabric.  Finally. MPLS at Layer
3.

What portion of network do you control.  Can you "own" the whole segment
from customer device to customer device?  In that case Q-in-Q is the
cheapest by far.

Regards,

Mike
