Abstract: With the large and medium-sized enterprise information system has been widely applied and in-depth development, customer for the reliability of the system have become increasingly demanding. How to ensure that the router fails when a communications link maintaining Unicom, ensure application service is not affected customers is the comparison of concern, is also the enterprise must urgently problem to solve. This design by setting the Cisco router so that the corresponding server in the network are connected, the application of HSRP technology, a router on the corresponding settings, the successful implementation of a hot standby experiment.
