VLAN(Virtual Local Area Network)的中文名為"虛擬局域網(wǎng)"。VLAN是一種將局域網(wǎng)設(shè)備從邏輯上劃分成一個(gè)個(gè)網(wǎng)段，從而實(shí)現(xiàn)虛擬工作組的新興數(shù)據(jù)交換技術(shù)。本文是小編帶來(lái)如何實(shí)現(xiàn)同一路由器不同vlan之間的通信，大家可以參考了解下！

先把pc上的ip都配好。開(kāi)始設(shè)置

switch0：

>en

>conf t

>vlan 2

>exit

>int fa 0/1

>switchport access vlan 2

>exit

>int fa 0/2

>switchport access vlan 2

>exit

>int fa 0/3

>switchport mode trunk

>end

switch1:

>en

>conf t

>vlan 3

>exit

>int fa 0/1

>switchport access vlan 3

>exit

>int fa 0/2

>switchport access vlan 3

>exit

>int fa 0/3

>switchport mode trunk

>end
