| Zusammenfassung: | The invention discloses a path detection method. The path detection method is applied to a source routing device of a long-term evolution LTE network, the LTE network comprises a two-layer virtual private network L2 and a three-layer virtual private network L3, the method comprises the following steps: obtaining configuration information, wherein the configuration information comprises a detection identifier, a source address and a destination address, the source address is the address of the source routing device of the L2 layer, and the destination address is the address of a destination routing device of the L3 layer, determining a detection path from the source routing device of the L2 layer to the destination routing device of the L3 layer according to the source address and the destination address, generating a heartbeat message according to the detection identifier, and sending the heartbeat message to a next hop routing device of the source routing device on the detection path. By adopting the path de |
