实验目的：
1、掌握基于多层交换的VLAN间路由的配置。
实验拓扑图：
实验步骤及要求：
1、首先配置PC1和PC2主机地址，本实验使用了两台路由器模拟PC主机。
2、配置如下所示：
PC1（config）#interfacefastethernet0/0
PC1（config-if）#ipaddress192.168.1.10255.255.255.0
PC1（config-if）#noshutdown
PC1（config-if）#exit
PC1（config）#
PC1（config）#noiprouting
PC1（config）#
PC1（config）#ipdefault-gateway192.168.1.1
PC2（config）#interfacefastethernet0/0
PC2（config-if）#ipaddress192.168.2.10255.255.255.0
PC2（config-if）#noshutdown
PC2（config-if）#exit
PC2（config）#
PC2（config）#noiprouting
PC2（config）#
PC2（config）#ipdefault-gateway192.168.2.1
3、在交换机上配置VLAN，同时将连接到客户端的端口按拓扑分入不同的VLAN中，配置如下：
SW1（config）#vlan10
SW1（config-vlan）#namecisco
SW1（config-vlan）#exit
SW1（config）#
SW1（config）#vlan20
SW1（config-vlan）#nameMicrosoft
SW1（config-vlan）#exit
SW1（config）#
SW1（config）#interfacefastethernet1/11
SW1（config-if）#switchportaccessvlan10
SW1（config-if）#exit
SW1（config）#
SW1（config）#interfastEthernet1/12
SW1（config-if）#switchportaccessvlan20
SW1（config-if）#exit
SW1（config）#
SW1（config）#interfacevlan10
SW1（config-if）#ipaddress192.168.1.1255.255.255.0
SW1（config-if）#noshutdown
SW1（config-if）#exit
SW1（config）#
SW1（config）#interfacevlan20
SW1（config-if）#ipaddress192.168.2.1255.255.255.0
SW1（config-if）#noshutdown
SW1（config-if）#exit
SW1（config）#
SW1（config）#iprouting
SW1（config）#
4、查看SW1交换机的VLAN配置，确认VLAN：
SW1#showvlan
