华为多VLAN的DHCP中继配置

时间：2024-10-12 22:12:05

实验要求： ①、Switch1、Switch2、Switch3作为接入二层交换机；创建Vlan100、Vlan200、Vlan300作为业务Vlan；创建Vlan999作为设备的管理Vlan。 ②、Switch1的GigabitEthernet0/0/1~16口配置Vlan100；GigabitEthernet0/0/24口配置为上联口，上联到路由器Switch0。 ③、Switch2的GigabitEthernet0/0/1~8口配置Vlan100、GigabitEthernet0/0/9~16口配置Vlan200；GigabitEthernet0/0/24口配置为上联口，上联到路由器Switch0。 ④、Switch3的GigabitEthernet0/0/1~8口配置Vlan200、GigabitEthernet0/0/9~16口配置Vlan300；GigabitEthernet0/0/24口配置为上联口，上联到路由器Router。 ⑤、在核心路由器Router上旁路接入DHCP Server，并配置成DHCP服务器，分别为Vlan100、Vlan200、Vlan300提供IP地址的分发业务。 ⑥、使部署在Vlan100上的PC1、Vlan200上的PC2和PC4、Vlan300上的PC3、PC5之间能够互相通讯；并且每台PC均能与网络上的交换机、路由器进行通讯。

拓扑结构说明：

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。
