使用gns3配置不同vlan间通讯

1、使用gns3配置不同vlan间通讯在gns3中用路由器模拟交换机，这里用r1,r2模拟交换机，r3,r4,r5模拟主机！详细配置过程：R1:r1#vlan database 创建vlan:r1(vlan)# vlan 10VLAN 10 added:Name: VLAN0010r1(vlan)# vlan 20VLAN 10 added:Name: VLAN0020r1(vlan)#exiAPPLY completed.Exiting.r1#r1#show vlan-switch 查看vlan的配置情况VLAN Name Status Ports- - - -1 default active
