A method for establishing tunnels includes establishing a first unidirectional tunnel from a first node to a second node, and sending a first instruction for establishing a reverse tunnel of the first tunnel, when sending the first instruction to the second node, triggering the establishment of a second unidirectional tunnel from the second node to the first node, and binding the second tunnel to the first tunnel as the reverse tunnel of the first tunnel. A system for establishing tunnels is also provided. The establishment of a reverse tunnel may be automatically triggered after a forward tunnel is established, and a bidirectional tunnel is established.

Method and system for establishing tunnels

A method, device, and system for establishing a label switching path (LSP) in fast rerouting (FRR) switching are provided, which can ensure that an ingress point and a merge point (MP) refresh path information in time. The method includes that first messages are respectively sent to an ingress point and an MP on an LSP, where the first messages carry information of holding a path refreshing state, so that the ingress point and MP determine the time of holding the path refreshing state according to the information of holding the path refreshing state; and second messages are respectively sent to the ingress point and the MP in the time of holding the path refreshing state, where the second messages carry information of refreshing a path state, so that the ingress point and MP establish the LSP according to the information of refreshing the path state.
