ABSTRACT:
A device provides layer two (L2) services between customer networks that are coupled by one or more intermediate computer networks. The device comprises a routing process that receives label information for a label switched path (LSP) through the intermediate networks. The device further comprises a L2service that receives L2service information from a device associated with second customer networks. In accordance with the label information, the device transports L2communications between the first and second customer networks through the one or more intermediate networks. By utilizing label information in this manner, the device may minimize the impact of providing L2services through the intermediate networks.
