本任务旨在实现华为ENSP中模拟网络设备与真实的外网之间的相互访问。

一、安装软件

eNSP V1.2.00.510

VirtualBox-5.1.24-117012-Win

WinPcap_4_1_3

wireshark-win32-1.4.3

百度网盘https://pan.baidu.com/s/1PXm8vg725hbW1kEmYBw1vA  提取码：4rrl

二、添加Loopback环回网卡

1、运行cmd：HDWWIZ，单击确定

2、在添加硬件界面，单击下一步

3、选择 手动安装列表

 

4、单击 显示所有设备

 5、在厂商类别中找到Microsoft，型号选择：Microssoft KM-TEST适配器，单击 下一步

 

6、 下一步 至安装结束

 三、网络拓扑图

 四、开始配置

1、配置云：右键cloud，进入设置，添加环回网卡以太网4--192.168.7.50和UDP映射
 

 2、配置共享本地网卡

在网络适配器设置中，右键本地以网卡，属性中勾上允许其他网络用户通过计算机的Internet连接来连接，选项上选择环回网卡以太网4，点确定。完成将本地网络共享到环回网卡。

 3、配置AR1

配置GE0/0/0 IP地址：192.168.137.123  255.255.255.0

<Huawei>sys
Enter system view, return user view with Ctrl+Z.

 4、配置PC1、PC2

此时ifconfig查看PC1的IP，发现无法获取IP，原因是我们没有配置DHCP，接下来我们配置DHCP。

 5、配置DHCP

AR1的配置
