第一部分测试结果：

1.链路聚合活跃为2，备用为1。

2.sw1上pc1和pc3为master，sw2上pc2和pc4为master。

第二部分：RIP、OSPF和BGP

第二部分要求：

• AS100做RIP，AS200做OSPF、AS300做静态路由；
• 使用BGP协议，使得主机可以正常和服务器Server通信；

第二部分测试结果：

1.各主机都可以正常和服务器Server通信。

第三部分：DHCP、NATServer和AS-PATH

第三部分要求：

1. Client1 可以通过公网上的R6 g/0/01接口访问Server的8080接口。
2. R5为DHCP服务器，R6为DHCP中继服务器，通过相关配置使得PC5 和PC6 可以自动获取IP地址；
3. 要求R1到R6的数据在R2处选择从R4走，R6到R1的数据在R处选择从R3走。

R6新增NATServer配置如下：

R3新增AS-PATH配置如下：

###################################下列为AS-PATH配置################################################

第三部分测试结果：

1.如下图所示，服务器上开启80端口后，Client可以通过访问服务器映射在公网的IP地址正常访问服务器，达到隐藏服务器的真实IP效果。

2.如下图所示：PC5和PC6可以通过DHCP服务器自动获取IP地址，由于华为系统默认排序从大到小，所以PC5和PC6的IP地址分别为：192.168.6.254和192.168.6.253

3.如下图一所示：在未配置AS-PATH之前，R1到R6数据来回都是选择从R3传递。

配置完AS-PATH后R1到R6的数据在R2处选择从R4走了，R6到R1的数据在R处选择从R3走了。
