核心交换机划分Vlan，并完成各Vlan的DHCP地址分配，同时，设定路由，通向出口路由器。而路由器划分子接口，完成与核心交换机发来的不同Vlan包的数据转发。实验用的设备均为H3C设备。
方法/步骤
1、在核心交换机上需要有三种配置：Vlan划分、Vlan接口的IP地址配置及每个Vlan接口应用DHCP地址池;配置DHCP地址池，开启DHCP服务。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-viewSystemView:returntoUserViewwithCtrl+Z.[H3C-GigabitEthernet1/0/1]vlan2[H3C-vlan2]vlan3[H3C-vlan3]quit[H3C]interfaceGigabitEthernet1/0/1[H3C-GigabitEthernet1/0/1]portaccessvlan2[H3C]interfaceGigabitEthernet1/0/3[H3C-GigabitEthernet1/0/3]portaccessvlan3[H3C-GigabitEthernet1/0/3]quitVlan接口的IP地址配置：[H3C]interfaceVlan-interface2[H3C-Vlan-interface2]ipaddress192.168.2.25424[H3C-Vlan-interface2]quit[H3C]interfaceVlan-interface3[H3C-Vlan-interface3]ipaddress192.168.3.25424[H3C-Vlan-interface3]quit每个Vlan接口应用DHCP地址池：[H3C]interfaceVlan-interface2[H3C-Vlan-interface2]dhcpselectserver[H3C-Vlan-interface2]dhcpserverapplyip-poolvlan2[H3C-Vlan-interface2]quit[H3C]interfaceVlan-interface3[H3C-Vlan-interface3]dhcpselectserver[H3C-Vlan-interface3]dhcpserverapplyip-poolvlan3[H3C-Vlan-interface3]quit
3、配置DHCP地址池，开启DHCP服务。---------------------------颍骈城茇------------------------------------------------幻腾寂埒-----[H3C]dhcpserverip-poolvlan2[H3C-dhcp-pool-vlan2]network192.168.2.0mask255.255.255.0[H3C-dhcp-pool-vlan2]gateway-list192.168.2.254[H3C-dhcp-pool-vlan2]dns-list202.102.128.68[H3C-dhcp-pool-vlan2]quit[H3C][H3C]dhcpserverip-poolvlan3[H3C-dhcp-pool-vlan3]network192.168.3.0mask255.255.255.0[H3C-dhcp-pool-vlan3]gateway-list192.168.3.254[H3C-dhcp-pool-vlan3]dns-list202.102.128.68[H3C-dhcp-pool-vlan3]quit[H3C][H3C]dhcpenable
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]interfaceGigabitEthernet1/0/2[H3C-GigabitEthernet1/0/2]portlink-typetrunk[H3C-GigabitEthernet1/0/2]porttrunkpermitvlan23[H3C-GigabitEthernet1/0/2]quit[H3C]设定Vlan包去路由器的默认静态路由[H3C]iproute-static0.0.0.00.0.0.0192.168.2.253[H3C]iproute-static0.0.0.00.0.0.0192.168.3.253192.168.2.253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。
5、在路由器上设定两种配置：配置路由子接口的IP地址和每个子接口终结Vlan的VID。开启环回口，模拟公网IP。
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-viewSystemView:returntoUserViewwithCtrl+Z.[H3C]interfaceGigabitEthernet0/1.2[H3C-GigabitEthernet0/1.2]ipaddress192.168.2.25324[H3C-GigabitEthernet0/1.2]vlan-typedot1qvid2[H3C-GigabitEthernet0/1.2]quit[H3C]interfaceGigabitEthernet0/1.3[H3C-GigabitEthernet0/1.3]ipaddress192.168.3.25324[H3C-GigabitEthernet0/1.3]vlan-typedot1qvid3[H3C-GigabitEthernet0/1.3]quit
7、开启环回口，模拟公网IP。[H3C]interfaceLoopBack0[H3C-LoopBack0]ipaddress202.102.128.6832
8、在计算机上自动获取IP，并测试连通性
