Abstract:
1. A method for establishing a pseudo wire, comprising: receiving, by a switching provider edge, a label mapping message sent by a terminating provider edge (TPE) connected to a customer edge, wherein the label mapping message comprises information of a switching provider edge at a bifurcation position, and information of at least two outgoing interfaces of the switching provider edge at the bifurcation position, the switching provider edge at the bifurcation position implements redundancy protection of a pseudo wire, wherein the switching provider edge at the bifurcation position reaches the TPE through the at least two outgoing interfaces; parsing, by the switching provider edge that receives the label mapping message, the label mapping message to obtain the information of the switching provider edge at the bifurcation position, and the information of the at least two outgoing interfaces; and comparing information of the switching provider edge that receives the label mapping message with the information of the switching provider edge at the bifurcation position, and if the information of the switching provider edge that receives the label mapping message matches with the information of the switching provider edge at the bifurcation position, establishing at least two pseudo wires from the switching provider edge that receives the label mapping message according to the information of the at least two outgoing interfaces, wherein one of the at least two pseudo wires is set as an active pseudo wire and another pseudo wire of the at least two pseudo wires is set as a standby pseudo wire.
