Abstract: A method, a system, and a device for establishing a pseudo wire are disclosed. The method includes: receiving, by a switching provider edge at a bifurcation position, a label mapping message, obtaining information of the switching provider edge at the bifurcation position and information of at least two next hops or outgoing interfaces of the switching provider edge through parsing, comparing the information of the switching provider edge at the bifurcation position with information of a local device, and if the information of the switching provider edge at the bifurcation position matches with the information of the local device, establishing at least two pseudo wires from the switching provider edge according to the information of at least two next hops or outgoing interfaces.
