Is this what you mean?

If so, Cisco uses the term of private vlan's which I think is a completly different concept than q-in-q tunneling.

Hi Nishikant,

I am not sure I understand what you mean by Aggregated VLANs
concept???  Do you mean an aggregated policer???  I can better help
explain the difference between Q-Q and something else if you clarify.
Oftentimes Q-Q is confused with L2protocol-Tunneling as well.
