The present invention provides a method and a local repair point node re routing, the method includes: a PLR node receives the RESV message, if according to the downstream node information of the RESV message carried by the judge backup tunnel destination node does not satisfy the preset rerouting conditions from the downstream of the downstream node to find the re routing conditions of node information, to determine if the tunnel path between the downstream node and find the node and the main tunnel path do not coincide, then select the tunnel path between the downstream node and the node and the main tunnel forming path rerouting relationship. According to the relationship between the protection of the invention can improve the cross node protection, to avoid the adjacent two link has failure, caused by tunnel protection resulted from the failure of data loss, ensure continuous two link failure, switch protection can come into effect.

【技术保护点】
１．一种重路由的方法，包括：本地修复点节点接收到资源预留（ＲＥＳＶ）消息后，若根据所述ＲＥＳＶ消息携带的下游节点信息判断预置的备份隧道目的地节点不满足重路由条件，则从所述下游节点信息中查找满足所述重路由条件的下游节点，若判断查找到的下游节点与本节点之间的隧道路径与主隧道路径不重合，则选择该下游节点与本节点之间的隧道路径与主隧道路径形成重路由关系。
