华为多VLAN的DHCP中继配置
1、 ①、PC1、PC2、PC3、PC4、PC5设置动态获取IP地址。
②、Switch1、Switch2和Switch3作为接入交换机。Switch0作为汇聚交换机，可以不做Vlan其他非实验的Vlan配置。
③、在路由器Router旁路接入DHCP Server，作为DHCP服务器，分别为Vlan100、Vlan200、Vlan300提供IP地址的分发业务。路由器Router上配置DHCP中继。
④、如拓扑结构中所标示，为各个设备的管理地址。
2、平台搭建：
①、按照拓扑结构图所示，摆放好设备，并使用直连线连接好各个设备。
②、开启所有的设备。

1、检验PC1、PC2、PC3、PC4、PC5获取的IP地址信息
所有PC均正常从路由器Router上正确获取IP地址等参数。
2、PC1到PC3、PC1到PC5、PC3到PC5的连通测试
所有的通讯测试均正常。
3、PC1到Router、DHCPServer的连通测试（这里直接对Router、DHCPServer的管理地址进行测试）
4、PC1到Switch0、Switch1、Switch2、Switch3的连通测试
所有的通讯测试均正常。
