Summary
A crude example of the usefulness of 802.1QnQ. A Service Provide (SP) is shown connecting two customers' ("Acme" and "XYZ") networks in a sort of L2 VPN. The customers run multiple VLAN's (single tagged traffic) into the SP switches; the SP switches send QinQ encapsulated traffic to one another; each customer has his own outer tag VLAN id, to segregate traffic.
