QinQ facilitates the creation of nested VLANs by using double VLAN tagging, enabling finer segmentation and isolation of traffic within a network environment. This approach is particularly valuable in service provider networks where you need to deliver VLAN-based services to multiple customers over a common infrastructure, while ensuring separation and isolation of traffic.
When two VLAN tags are present in a packet, the outer VLAN tag can be either 802.1Q or 802.1ad. The inner VLAN tag must always be 802.1Q.
