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. |

1. A method for generating, by a transport network device of a second type, information about a newly added port belonging to a linked device of a first type and associated with a transparent LAN segment, the information to be disseminated to other devices of the second type, the method comprising:
a) obtaining, by the transport network device, a set of labels associated with the newly added port; and b) generating, by the transport network device, at least one message, the at least one message collectively including
i) a first field for identifying the device of the second type;ii) a second field for identifying the transparent LAN segment to which the newly added port belongs,iii) a third field for identifying the device of the first type in the context of the transparent LAN segment, andiv) a fourth field for identifying the set of labels. |
