ABSTRACT:
A transport LAN segment service is provided over a transport network. Responsibilities for configuring, provisioning and forwarding over a transport LAN segment are divided between layer 2 and 3 service provider edge devices, where the layer 3 edge device handles discovery and tunneling responsibilities, the layer 2 edge device handles learning and flooding responsibilities, and information can be exchanged between the layer 2 and 3 edge devices. Configuration is simplified by advertising TLS-label information, layer 2 address learning, and flooding when the needed configuration information has not yet been learned or discovered.
