IEEE 802.1Q Tunneling
IEEE 802.1Q Tunneling (QinQ) is designed for service providers carrying traffic for
multiple customers across their networks. QinQ tunneling is used to maintain
customer-specific VLAN and Layer 2 protocol configurations even when different
customers use the same internal VLAN IDs. This is accomplished by inserting
Service Provider VLAN (SPVLAN) tags into the customer’s frames when they enter
the service provider’s network, and then stripping the tags when the frames leave
the network.
