一、实验目的
1) 熟悉路由器或路由器模拟器的基本用法
2) 设计子网划分方案，配置路由器相关接口
3) 配置静态路由，使网络连通
4) 配置动态路由协议RIP，使网络连通
二、实验内容
一、配置静态路由，实现处于两个不同网络的主机的通信
(1)进入Packet Tracer的主页面，选择三个2621XM路由器Routers1、Routers2、Routers3和两台主机PC0、PC1；
(2)配置路由器Routers1的IP，单击Routers2，进入Routers2的配置界面，为Routers2选择两个网卡；输入命令enable进入特权模式，输入config t进入配置模式，interface FastEthernet0/0表示开始为端口FastEthernet0/0配置IP，ip address 192.168.0.1 255.255.255.0为FastEthernet0/0配置好IP地址和子网掩码；同样为interface FastEthernet0/1配置IP为ip address 192.168.1.1 255.255.255.0；
(3)同理，为Routers1的端口FastEthernet0/0配置IP为ip address 192.168.2.1 255.255.255.0，端口FastEthernet0/1配置IP为ip address 192.168.0.2 255.255.255.0；为Routers3的端口FastEthernet0/0配置IP为ip address 192.168.1.2 255.255.255.0，端口FastEthernet0/1配置IP 为ip address 192.168.3.1 255.255.255.0；为主机PC0配置IP为192.168.2.2，子网掩码为255.255.255.0，默认网关为192.168.2.1；为主机PC1配置IP为192.168.3.2，子网掩码为255.255.255.0，默认网关为192.168.3.1；配置完毕后，其连接如下图所示：

(4)输入命令ip route 为路由Routers1添加路由ip route 192.168.1.0 255.255.255.0 FastEthernet0/1；ip route 192.168.3.0 255.255.255.0 FastEthernet0/1，为Routers2添加路由ip 192.168.2.0 255.255.255.0 FastEthernet0/0；ip 192.168.3.0 255.255.255.0 FastEthernet0/1，为Routers3添加路由ip 192.168.0.0 255.255.255.0 FastEthernet0/0；ip 192.168.2.0 255.255.255.0 FastEthernet0/0。

配置完毕后，推出配置模式，输入show ip route 查看已经配置好的路由。

最后在PC0的Command Prompt 输入ping 192.168.3.2 得到的结果如：
PC>ping 192.168.3.2

在PC1中的Command Prompt输入ping 192.168.2.2 得到的结果如：
PC>ping 192.168.2.2

二、配置静态路由，实现处于两个不同网络的主机的通信
(1)进入Packet Tracer的主页面，选择三个2621XM路由器Routers4、Routers5、Routers6
和两台主机PC0、PC1；
(2)Routers4、Routers5、Routers6的IP配置分别与上面的静态路由Routers1、Routers2、
Routers3相同。

此处的PC0和PC1与上面的静态路由PC0、PC1相同。

其连接如下图所示：

(3)在Routers4中的RIP Routing添加network address192.168.1.0和192.168.2.0；在Routers5
中的RIP Routing添加network address192.168.0.0和192.168.1.0；在Routers6中的RIP Routing添加network address192.168.0.0和192.168.3.0。

(4)主机PC0 ping主机PC1得到结果如下:
PC>ping 192.168.3.2
