1、首先搭建网络拓扑图，将三台PC机接入交换机，交换机接入路由器。

2、在交换机上设备vlan接口，vlan10 vlan20 vlan30 vlan40 ，是PC1接入vlan10，PC2接入vlan20,PC3接入vlan30 ，路由器接入vlan40.

3、给每个vlan创建一个网段，VLAN 10 IP 为192. 168.0.0/24网段 VLAN 20 IP为192. 168.1.0 / 24网段，vlan30 IP为192. 168.2.0/24网段，vlan40 IP为172.168. 0.0/24 网段。

4、设置每天vlanIF接口为中继，并指定DHCP 地址。如：interfaceVlanif10ipaddress192. 1鲂番黟谊68.0.1255.255.255.0dhcpselectrelaydhcprelayserver-ip172. 168.0.2#interfaceVlanif20ipaddress192.168 .1.1255.255.255.0dhcpselectrelaydhcprelayserver-ip172. 168.0.2#interfaceVlanif30ipaddress192. 168. 2.1 255.255.255.0dhcpselectrelaydhcprelayserver-ip172 .168.0.2#interfaceVlanif40ipaddress172. 168.0.1 25 5.255.255.0

5、在交换机做设置：sysnameR1#vlanbatch10203040#dhcpenable#ippoolvlan10gateway-list192.168.0.1network192.168.0.0mask255.255.255.0excluded-ip-address192.168.0.100192.168.0.254dns-list192.168.0.1#ippoolvlan20gateway-list192.168.1.1network192.168.1.0mask255.255.255.0leaseday2hour12minute30dns-list192.168.1.1#ippoolvlan30gateway-list192.168.2.1network192.168.2.0mask255.255.255.0dns-list192.168.2.1#interfaceVlanif10#interfaceGigabitEthernet0/0/0ipaddress172.168.0.2255.255.255.0dhcpselectglobal#interfaceNULL0#iproute-static0.0.0.00.0.0.0172.168.0.1#user-interfacecon0user-interfacevty04user-interfacevty1620#Return

6、设置完成。查看PC机IP地址。
