实验步骤
SW1
配置的接口
配置的DHCP
配置缺省路由

 interface GigabitEthernet0/0/1 port link-type access port default vlan 10  interface GigabitEthernet0/0/2 port link-type trunk port trunk allow-pass vlan 2 to 4094  DHCP配置在交换机SW2上 1.dhcp enable 2.ip pool 1 network 192.168.1.0 mask 255.255.255.0 dns-list 192.168.4.1 gateway-list 192.168.1.254    3.vlan batch 10 20 4.int vlanif 10 ip address 192.168.1.254 255.255.255.0 dhcp select global 5.display ip pool 

AR1
配置接口
配置nat
配置地址组
配置acl
进入端口使用acl
配置缺省路由
配置静态路由
