為使路由器運行新的Cisco IOS軟件鏡像，您需要重新加載路由器。請確保您已發(fā)出 copy running-config starting-config 命令或者 write memory 命令來保存配置。
3600#write memory
3d01h: %SYS-5-CONFIG_I: Configured from console by vty0 (127.0.0.11)
Building configuration...
3600#reload
步驟 7: 檢驗升級
當路由器開啟后，請通過發(fā)出 show version 命令確保您當前運行的是新版本。
3640#show version
