终端通过三台路由器相互通信（静态路由设置）

一、示意图

二、IP规划

1) 配置终端IP地址、子网掩码、网关。
   Laptop0：192.168.0.100 255.255.255.0 192.168.0.1
       PC0：172.16.0.100 255.255.0.0 172.16.0.1
2) 配置路由端口的IP地址。
   Router1-Fa0/0：ip address 123.0.0.2 255.0.0.0
   Router1-Fa0/1：ip address 130.0.0.2 255.255.0.0
   Router0-Fa0/1：ip address 192.168.0.1 255.255.255.0
   Router0-Fa0/0：ip address 123.0.0.1 255.0.0.0
   Router2-Fa0/1：ip address 172.16.0.1 255.255.0.0
   Router2-Fa0/0：ip address 130.0.0.1 255.255.0.0

三、操作步骤

   Router0：ip route 130.0.0.1 255.255.0.0 123.0.0.2
   Router0：ip route 172.16.0.1 255.255.0.0 123.0.0.2
   Router2：ip route 123.0.0.1 255.0.0.0 130.0.0.2
   Router2：ip route 172.16.0.1 255.255.0.0 130.0.0.2
   Router1：ip route 192.168.0.1 255.255.255.0 123.0.0.1
   Router1：ip route 172.16.0.1 255.255.0.0 130.0.0.1
