摘要：
The invention describes a new feature for a network element or a router (IP-NIU). The feature is implemented in said router as a route manager object (RIISTA). The first function of the feature is realised by trapping the routing messages that any process like routing daemon or the route manager object sends to the input/output manager and sending them forward to the appropriate function. The second function of the feature is realised by copying the routing messages from the active unit (IP-NIU WO) to the other instance of the route manager (RIISTA_SL) running in the spare unit(IP-NIU SP).
