METHOD, SYSTEM, AND DEVICE FOR ESTABLISHING PSEUDO WIRE

摘要

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.

1. A method for establishing a pseudo wire, comprising:
receiving, by a switching provider edge, a label mapping message, wherein the label mapping message comprises information of a switching provider edge at a bifurcation position, the label mapping message further comprises information of at least two next hops or information of at least two outgoing interfaces of the switching provider edge at the bifurcation position; parsing, by the switching provider edge, the label mapping message to obtain the information of the switching provider edge at the bifurcation position, and to obtain the information of at least two next hops or the information of at least two outgoing interfaces; and comparing, by the switching provider edge, information of the switching provider edge with the information of the switching provider edge at the bifurcation position, and if the information of the switching provider edge matches with the information of the switching provider edge at the bifurcation position, establishing at least two pseudo wires from the switching provider edge according to the information of at least two next hops or the information of at least two outgoing interfaces.
