用 GNS3 做CCNA网络实验(4)
7. 路由实验： 静态路由 Static Routing
(1) 准备实验
我们假定是关闭 GNS3 后重新打开 GNS3 开始新的实验。
先为这次实验准备一个子目录，例如 在 gns3Project 下建一个子目录 stat1.
在 GNS3 打开我们以前保存的已经测试过的 topology， 例如 router1.net 然后装入配置文件。
在 GNS3 菜单 File -> Save topology as 把这个 topology 改名为 statr1.net 并保存 到 stat1 子目录下。
在 菜单 File -> Import/Export 选 Export to a directory 把原来的配置卸出到子目录 stat1 下。
这样，下面的实验所用到的 topology 和更改配置后的保存都放在这个子目录下。
（2） 查看当前路由信息
启动各个路由器 （R1, R2 和 PC1, PC2）.
R1 的输出：
R2 的输出：
（3） 配置路由器
按照这个 topology， 路由器 R1 直接连接 2 个网段， 网络地址分别为： 192.168.100.0 和 172.17.1.0
而数据包要发送到 网段 192.168.110.0， 则需要经过 R2 的端口 s2/1 进入，这个端口的地址是 172.17.1.2
我们就在 R1 输入：
同样， 路由器 R2 直接连接 2 个网段， 网络地址分别为： 192.168.110.0 和 172.17.1.0
数据包要发送到 192.168.100.0 网段，是要经过 R1 的端口 s2/0 进入， 这个 s2/0 的地址是 172.17.1.1
我们在 R2 输入：
(3) 测试
