步骤6：重新启动路由器以加载新镜像

　　为使路由器运行新的Cisco IOS软件镜像，您需要重新加载路由器。请确保您已发出 copy running-config starting-config 命令或者 write memory 命令来保存配置。

　　3600#write memory

　　3d01h: %SYS-5-CONFIG_I: Configured from console by vty0 (127.0.0.11)

　　Building configuration...

　　3600#reload

　　步骤 7: 检验升级

　　当路由器开启后，请通过发出 show version 命令确保您当前运行的是新版本。

　　3640#show version
