目的:让PC1 ping通 PC3 ,PC2 ping通 PC4
PC1配置ip地址 # PC的网关指向vlan的ip地址

LSW1:
vlan batch 10 20 #在交换机上创建vlan 10 和 vlan 20
interface Vlanif10                  #进入vlan 10
  ip address 192.168.10.254 255.255.255.0     #给vlan 10配置ip地址
interface Vlanif20                #进入vlan 20
  ip address 192.168.20.254 255.255.255.0     #给vlan 20配置ip地址
interface GigabitEthernet0/0/1   #进入g0/0/1接口
  port link-type trunk                   #将此接口的模式改为trunk
  port trunk allow-pass vlan 2 to 4094    #配置此接口允许所有vlan通过
interface GigabitEthernet0/0/2     
  port link-type access                  #将此接口模式改为accrss
  port default vlan 10                    #只允许vlan 10通过
interface GigabitEthernet0/0/3
  port link-type access
  port default vlan 20
LSW2:
interface Vlanif10
  ip address 192.168.10.254 255.255.255.0
 interface Vlanif20
  ip address 192.168.20.254 255.255.255.0
 interface GigabitEthernet0/0/1
  port link-type trunk
  port trunk allow-pass vlan 2 to 4094
 interface GigabitEthernet0/0/2
  port link-type access
  port default vlan 10
 interface GigabitEthernet0/0/3
  port link-type access
  port default vlan 20
