Using bidirectional forwarding detection (BFD) technique detects state of virtual private local service (VPLS) network. If fault occurs in VPLS network, then, the method sets up service route (SR) in standby mode as main use state; and SR in main use state sends out service data. After network fault is recovered, the method sets up SR in low priority as standby mode, stopping sending service data in order to reduce time of interrupted multicast service caused by network fault in large degree. Further, quick testing is carried out for two pieces of unidirectional label switching path (LSP) of VPLS data link. When fault occurs in one directional LSP, the method stops transferring service data of other directional LSP in order to prevent abnormal service of edge router from occurring.
