核心交换机完成不同Vlan的DHCP地址分配
1、在核心交换机上需要有三种配置：1、Vlan划分、Vlan接口的IP地址配置及每个Vlan接口应用DHCP地址池;2、配置DHCP地址池，开启DHCP服务。3、去往路由器设定Trunk接口，设定Vlan去路由器的默认静态路由
2、外狒芙梨Vlan划分、Vlan接口的IP地址配置及每个Vlan接口应用DHCP地址池;----------------------------------------------幻腾寂埒----------------------------------划分Vlan:<H3C>system-viewSystem View: return to User View with Ctrl+Z.[H3C-GigabitEthernet1/0/1]vlan 2[H3C-vlan2]vlan 3[H3C-vlan3]quit[H3C]interface GigabitEthernet 1/0/1[H3C-GigabitEthernet1/0/1]port access vlan 2[H3C]interface GigabitEthernet 1/0/3[H3C-GigabitEthernet1/0/3]port access vlan 3[H3C-GigabitEthernet1/0/3]quitVlan接口的IP地址配置：[H3C]interface Vlan-interface 2[H3C-Vlan-interface2]ip address 192.168.2.254 24[H3C-Vlan-interface2]quit[H3C]interface Vlan-interface 3[H3C-Vlan-interface3]ip address 192.168.3.254 24[H3C-Vlan-interface3]quit每个Vlan接口应用DHCP地址池：[H3C]interface Vlan-interface 2[H3C-Vlan-interface2]dhcp select server[H3C-Vlan-interface2]dhcp server apply ip-pool vlan2[H3C-Vlan-interface2]quit[H3C]interface Vlan-interface 3[H3C-Vlan-interface3]dhcp select server[H3C-Vlan-interface3]dhcp server apply ip-pool vlan3[H3C-Vlan-interface3]quit
4、去往路由器设定Trunk接口，设定Vlan包去路由器的默认静态路由--------------------------------------------------------------------------------去往路由器设定Trunk接口[H3C]interface GigabitEthernet 1/0/2[H3C-GigabitEthernet1/0/2]port link-type trunk[H3C-GigabitEthernet1/0/2]port trunk permit vlan 2 3[H3C-GigabitEthernet1/0/2]quit[H3C]设定Vlan包去路由器的默认静态路由[H3C]ip route-static 0.0.0.0 0.0.0.0 192.168.2.253[H3C]ip route-static 0.0.0.0 0.0.0.0 192.168.3.253192.168.2.253 和 192.168.3.253是路由器子接口的地址。两条静态路由，没有设定优先级，优先级一样，故同时起作用。
6、配置路由子接口的IP地址和每个子接口终结Vlan的VID。--------------------------------------------------------------------------------<H3C>system-viewSystem View: return to User View with Ctrl+Z.[H3C]interface GigabitEthernet 0/1.2[H3C-GigabitEthernet0/1.2]ip address 192.168.2.253 24[H3C-GigabitEthernet0/1.2]vlan-type dot1q vid 2[H3C-GigabitEthernet0/1.2]quit[H3C]interface GigabitEthernet 0/1.3[H3C-GigabitEthernet0/1.3]ip address 192.168.3.253 24[H3C-GigabitEthernet0/1.3]vlan-type dot1q vid 3[H3C-GigabitEthernet0/1.3]quit
8、在计算机上自动获取IP，并测试连通性
