实验拓扑
拓扑分析
Access交换机配置直接可以当作二层交换机，只需要划分vlan10、vlan20两个vlan即可。
SW2 g0/0/22 不需要配IP地址，配置成trunk类型。并且创建vlan10 vlan20 ，分别给这两个vlan配置虚接口IP：Vlanif10 192.168.10.254 24，Vlanif20 192.168.20.254 24
SW2 g0/0/24 不需要配IP地址，只能把G0/0/24加入到vlan99，vlan99配置IP地址接口类型Access，同样需要给vlan99配置虚接口：Vlanif99 192.168.99.1，用于和路由器(R1)的g0/0/0通讯。
配置步骤
PC配置IP、子掩码、网关
SW1上二层交换机上划分VLAN，并把相应的PC接口加入
SW1、SW2之间的两个端口配置Trunk
SW2上面配置创建VLAN10/20/99，配置VTP，并把24口加入到vlan99，最后加一条静态路由指向网关。
R1配置接口信息，添加静态路由
R2配置接口信息，添加静态路由
SW1 Access接入交换机配置
Access交换机我们可以当他是二层交换机
