花了快一个月的时间之后，我的Linux服务器建设学习算是小告了一个段落了。现在开始要回到windows里面利用Boson NetSim这个cisco实验模拟器来加深对路由交换的配置学习了。好在上学期上课的时候学了一些路由器的知识，在实验室也做过一些实验，但大都比较简单，反正我觉得没学到什么高深的网络配置知识。趁着暑假，自己来做做模拟实验，也可以学到很多东西，今天是第一个比较简单的实验，但由于以前没涉及到某些方面，这样一个简单的实验还是花了我不少的时间的，呵呵，下面来看这个实验：
如上的拓扑所示，（IP地址是我自己确定的，并且用ps写上的，这样看得比较清楚），现在需要完成的就是让HostA能和HostB互相ping通，我在配置过程中遇到了一些问题，我都把容易出错的地方注释在下面的配置语句后面了，希望那些跟我一样在网络配置方面还处于初步的朋友一些帮助，还希望高手们不要见笑，并且给我多加指教，先谢谢了，好了，看我的具体配置如下：
router1的配置：
Press Enter to Start
Router>
Router>en
Router#conf t
Enter configuration commands, one per line. End with CNTL/Z.
Router(config)#hostname router1
