实验环境：

两台PC两台路由器

拓扑图:

需求描述：

通过PC端实现PC5与PC6的通信

实验步骤：

1.1两台路由器进行ip的配置：

两台路由器的各个端口配置都类似如下代码，这里就不重复描述了：

Router#conf t
Enter configuration commands, one per line.  End with CNTL/Z.
Router(config)#interface gigabitEthernet 0/0
Router(config-if)#ip address 192.168.1.254 255.255.255.0
Router(config-if)#no shutdown

1.2使用PC机器进行ping连接测试

我们使用PC5pingPC6试试看效果，再ping路由器试试看效果：

首先进入终端：

C:\>ping 192.168.5.1Pinging 192.168.5.1 with 32 bytes of data:Reply from 192.168.3.254: Destination host unreachable.
Reply from 192.168.3.254: Destination host unreachable.
Reply from 192.168.3.254: Destination host unreachable.
Reply from 192.168.3.254: Destination host unreachable.Ping statistics for 192.168.5.1:Packets: Sent = 4, Received = 0, Lost = 4 (100% loss),

pingPC6可以看到是成功的，再试试ping路由器Router4:

C:\>ping 192.168.2.254Pinging 192.168.2.254 with 32 bytes of data:Reply from 192.168.3.254: Destination host unreachable.
Reply from 192.168.3.254: Destination host unreachable.
Reply from 192.168.3.254: Destination host unreachable.
Reply from 192.168.3.254: Destination host unreachable.Ping statistics for 192.168.2.254:Packets: Sent = 4, Received = 0, Lost = 4 (100% loss),

说明我们的配置同行正常，可以使用：
