Addressing for customer premises lan expansion

A method, comprising:

• announcing, by a controller of a network device hosting a customer bridging domain associated with a customer network element of a customer toward a controller of a private data network hosting a customer component for the customer, an address of the customer bridging domain;
• receiving, by the controller from the customer bridging domain, an address resolution request of the customer component for a customer device associated with the customer network element of the customer, the address resolution request comprising an address of the customer device;
• and
• propagating, from the controller toward the customer bridging domain, an address resolution response for the customer component, the address resolution response comprising the address of the customer device and the address of the customer bridging domain.

An apparatus, comprising:

• a processor and a memory communicatively connected to the processor, the processor configured to:
• receive, by a customer bridging domain hosted by a network element for a customer, a packet intended for a customer device associated with a customer network element of the customer, wherein the packet comprises a Layer 2 (L2) address of the customer bridging domain;
• modify the packet at the customer bridging domain, by removing from the packet the L2 address of the customer bridging domain and inserting within the packet an L2 address of the customer device, to form a modified packet;
• and
• propagate the modified packet from the customer bridging domain toward the customer network element.
