The invention provides a method and a device for releasing a route. The method comprises: generating first route information by utilizing first route attribute information, releasing the first route information to first PE (Provider Edge) equipment by a routing protocol, wherein the first route information comprises a target network segment, a first priority and a next hop of information; enabling the first priority to be greater than a second priority of second route information released to the first PE equipment by second PE equipment, so that when no fault is generated between the first PE equipment and third PE equipment, traffic of the target network segment is sent by utilizing a first route generated on the basis of the first route information, and when a fault is generated between the first PE equipment and the third PE equipment, the traffic of the target network segment is sent by utilizing a second route generated on the basis of the second route information. In the embodiment of the invention, when the first PE equipment and the third PE equipment have faults, the traffic can be sent to target CE (Customer Edge) equipment, and thus, the traffic is guaranteed not to be interrupted, and the problem of service interruption is avoided.
