Abstract

A header value or label, referred to herein as a source station identification (SSID), is added to an encapsulated packet header, such as by adding the SSID as a label to the bottom of a stack of MPLS labels. The SSID comprises a unique identifier that identifies the PE that originated the packet. In some embodiments, the IP address of the originating PE may be used as the SSID for that PE. The PE receiving this packet can then associate the source Ethernet MAC address of received TLS traffic, e.g., with the originating PE. Given the SSID of the originating PE, the receiving PE is able to determine which LSP to use to send Ethernet traffic to the station with the learned MAC address.
