Abstract
In general, techniques are described for performing scalable layer two (L2) learning in computer networks. A network device that includes interfaces and a control unit may implement these techniques. The control unit stores a L2 learning table having entries that are each associated with a service tag identifying a service virtual local area network. In response to receiving a packet that includes a service tag, the interfaces access the L2 learning table using the service tag to determine whether any of the entries of the L2 learning table are associated with the service tag. When none of the entries are associated with the service tag, the L2 learning module updates the L2 learning table to create a new entry defining an association between the one of the interfaces that received the packet and the service tag.
