description In one embodiment, a first port of a device provides connectivity to a customer network and a second port of the device provides connectivity to a provider network. Frame mapping logic associated with the first port processes a network message received at the first port and accesses a Virtual Local Area Network (VLAN) mapping data structure that maps customer VLAN designations used in the customer network to provider VLAN designations used in the provider network. Frame mapping logic uses the VLAN mapping data structure to associate the received network message with a particular provider VLAN designation based upon the received network message's particular customer VLAN designation. The received network message is then passed toward the second port.
