Disclosed are a method, device and system for establishing an LSP. The method comprises: a proxy node device allocating a label for a destination node device to generate a label mapping message carrying the label, the address of the destination node device and the address of the proxy node device, and sending the label mapping message to an upstream node device to initiate the establishment a first LSP from an entry node device to the proxy node device; and the proxy node device adhering the first LSP with a second LSP to form a third LSP from the entry node device to the destination node device, wherein the second LSP is an LSP established between the proxy node device and the destination node device. By means of the technical solution in the embodiments of the present invention, the entry node device and an intermediate node device have no need to pre-configure a static route reaching the destination node device, which solves the problems in the prior art of complex configuration and difficult management and maintenance caused by being required to configure a static route when LSPs of different protocols are adhered. |
