Abstract
In general, techniques are described that facilitate scalable wholesale layer two (L2) connectivity between customers and service providers and a demarcation between the L2 wholesale network and one or more ISPs with which customers communicate L2 PDUs. In one example, a network device receives PDU having both a service identifier identifying a service virtual local area network (SVLAN) and a customer identifier identifying a customer VLAN (CVLAN). A virtual switch determines whether an entry of a L2 learning table is associated with both the service identifier and the customer identifier of the PDU. When no such entry exists, a VLAN learning module updates the L2 learning table to create a new entry that maps to a network device interface and is associated with both the service identifier of the PDU and a plurality of customer identifiers that includes the customer identifier of the PDU.
