ciscoLAN

由于实验需要&＃xff0c;需要搞个内部局域网&＃xff08;以前我们实验室是直接从学校拖了根线过来&＃xff0c;然后直接用switch连&＃xff09;。因此得先配个router&＃xff0c;做个小局域网。由于从没接触过路由器&＃xff0c;所以先去网上找了些资料&＃xff0c;接着就打开cisco2600开始配置&＃xff0c;设好了用户名和密码之后&＃xff0c;reload一下&＃xff0c;发现还是那个要你设置用户名和密码的dialog对话&＃xff0c;晕~~~~~~。试了好几次&＃xff0c;还是这样&＃xff0c;便去问个配置过路由器的朋友&＃xff0c;他试了几次还是如此&＃xff0c;只能打电话去问技术支持。老半天后&＃xff0c;才知道是0x42的寄存器有问题&＃xff0c;要把启动的寄存器改为0x2102。
      接着就进行配置了&＃xff0c;简单地做了个NAT&＃xff0c;由于我们学校有几个IP地址快一点&＃xff0c;所以就把自己的IP和那个快的IP做了个静态的一对一&＃xff0c;嘿嘿&＃xff01;不过还是真是懊恼&＃xff0c;因为路由器的命令和LINUX的命令不同&＃xff0c;所以我经常打错的。以下是我的配置&＃xff0c;由于对路由器配置不熟&＃xff0c;可能配的不是很好&＃xff0c;希望有高手看到&＃xff0c;指点一二&＃xff1a;
