The present invention provides a method for monitoring user edge router CE, when the monitored CE access to common CE, CE sends the message to be monitored by the monitoring of PE, PE by monitoring the message is forwarded to CE monitoring; monitoring CE of message processing, and forward the received message to the monitoring PE; PE will monitor message to general CE, general CE to process the received message, response message, and transmits the response message to the monitoring by monitoring PE; PE transmits the response message to the monitoring of CE, monitoring CE response message processing, and transmits the response message received to monitor PE, then by monitoring the PE response message will be forwarded to the monitored CE. The invention also discloses a routing device, routing device and method of the invention is applied to monitor CE, can not affect the other MPLS? L3VPN network flow situation, flexibly to monitor the monitored CE.
【技术实现步骤摘要】
【技术保护点】
一种对用户边缘路由器CE进行本地监控的方法,应用于三层多协议标签交换虚拟专用网络MPLSL3VPN三层网络中,其特征在于,该方法包括:由运营商边缘路由器PE为监控CE设置一个包含本地虚拟专用网络VPN_Local标签的特定下一跳,该特定下一跳的出接口为PE的本地监控CE的接口,将入接口或者出接口为被监控CE的报文的出接口设置成监控CE的接口;所述PE接收到从被监控CE上来的报文后,根据所述设置的入接口为被监控CE的报文的出接口为监控CE的接口,将所述报文重定向到为监控CE设置的特定下一跳,通过特定下一跳的出接口将报文转发到监控CE;所述PE接收到从普通CE上来且去往被监控CE的报文后,根据所述设置的出接口为被监控CE的报文的出接口为监控CE的接口,将所述报文重定向到为监控CE设置的特定下一跳,通过特定下一跳的出接口将报文转发到监控CE;所述PE接收到从监控CE上来的报文后,将报文转发到被监控CE或普通CE。
