Ospf路由配置，并于外界相连通。

一、 实验目的：
Ospf路由配置，并于外界相连通。

二、实验拓扑：

三、实验步骤：
将r0放入NM-1FE-TX和WIC-2T;

配置ip地址；

将r1和r2拓展—>NM-1FE-TX


对r0进行ospf配置
Ospf 10
R0(config-if)#exit
R0(config)#router ospf 10
R0(config-router)#net
R0(config-router)#network 172.16.1.0 0.0.0.3 area 0
R0(config-router)#network 172.16.2.0 0.0.0.3 area 0
R0(config-router)#network 192.168.1.0 0.0.0.255 area 0
R0(config-router)#end

Show ip route：R0
Gateway of last resort is not set

二、 实验结果：
PING R2

Ping r1

三、 实验心得：
在整个实验的过程中。主要设置路由的ip，添加opsf地址，掌握opsf的基本理论，另外了解了路由与外部链接的方法，但在实验的过程中还是不够熟悉，在课后还要多加练习，提高试验的效率。
