Abstract

Disclosed is a route detection method, applying to a source router device in a Long Term Evolution (LTE) network, wherein the LTE network comprises a Layer 2 virtual private network (L2VPN) and a Layer 3 virtual private network (L3VPN). The method comprises: acquiring configuration information, the configuration information comprising a detection identifier, a source address and a target address, the source address being an address of a source router device in the L2VPN, the target address being an address of a target router device in the L3VPN; determining, according to the source address and the target address, a detection route from the source router device in the L2VPN to the target router device in the L3VPN, and sending a heartbeat message, generated according to the detection identifier, to a next-hop router device of the source router device on the detection route. The route detection method provided in embodiments of the present invention can automatically detect a node failure on a transmission route from L2 to L3 in the LTE network.

Description

technical field [0001] The present invention relates to the technical field of communications, and in particular to a path detection method, routing device and system. Background technique [0002] With the rapid development of mobile communications, the characteristics of 4G networks such as large capacity, all-IP, and dynamic paths have brought new requirements for operation, administration and maintenance (operation, administration and maintenance) to the reliability of Long Term Evolution (LTE) services. , OAM) requirements. [0003] The LTE network includes a Layer 2 virtual private network (L2, Layer 2virtual private network) and a Layer 3 virtual private network (L3, Layer 3virtual private network). Internet Protocol (Internet Protocol, IP) layer network. [0004] In the prior art, the failure of the transmission path from the L2 to the L3 layer can only be detected by forging a special service message manually. Contents of the invention [0005] The embodiment o...
