A method is disclosed for use by a network element coupled with an optical transport network. The method comprises calculating an optical path from a first packet-terminated optical interface of the network element to a second packet-terminated optical interface of a destination network element coupled with the optical transport network, and signaling the optical transport network to create the optical path. The method further comprises creating an Ethernet interface corresponding to the first packet-terminated optical interface, and adding the Ethernet interface to an Ethernet bundle interface. The method further comprises communicating across the optical path using addressing of the Ethernet bundle interface.
