Abstract
A method for obtaining path association information, a device, and a system are provided, and belong to the field of network technologies. A first network device generates a packet carrying template indication information, and sends the packet to a second network device. After receiving the packet, the second network device determines, based on the template indication information carried in the packet, a target template associated with a target forwarding path, and performs, based on the target template, an operation associated with the target forwarding path. In this way, the first network device may include template indication information corresponding to different templates in a packet, to indicate different receiving network devices to determine a target template associated with a target forwarding path, and determine, based on the target template, association information such as a path attribute or a path constraint associated with the target forwarding path. The path association information is advertised in a manner of carrying the template indication information provided in this method, so that flexibility of obtaining the path association information can be improved without affecting protocol stability.
