Router(config-router)#end
Router#
%SYS-5-CONFIG_I: Configured from console by console
5、测试网络的连通性
从pc0 ping pc1和网络跟踪命令：
六、实验总结：
本次实验遇到的最大的问题是在前期准备阶段，画好拓扑图并进行连接的时候，即便我按照实验指导配好了相关的指令，还是不能连通路由器RB和PC1，后来索性换了一根线缆，就妥了。
首先百度得知，直通线是用来连接直通线是将不同设备连接在一起，比如电脑和交换机，而交叉线是用来连接相同类型的设备的。后来通过进一步的了解得知，现在较新设备的网口都支持自动识别直通线或交叉线，因而交叉线正在逐渐消亡。虽然依然很迷，但是起码它最后还是通了。
配置OSPF协议也是完全通过百度搜相关资料才解决的。 标签：6.13,router,down,Switch,172.16,Router,config From： https://www.cnblogs.com/binglinll/p/18252272
