摘要：
A new feature for a network element or a router is described herein. The feature is implemented in the router as a route manager object. The first function of the feature is realized by trapping routing messages that any process like routing daemon or the route manager object sends to the input/output manager and sends them forward to an appropriate function. The second function of the feature is realized by copying the routing messages from an active unit to another instance of the route manager running in the spare unit.
