VLAN作成

Router#vlan database
Router(vlan)#vlan 10
VLAN 10 added:
    Name: VLAN0010
Router(vlan)#applyAPPLY completed.

VLANをinterfaceに割り当てる

Router(config)#interface FastEthernet 2
Router(config-if)#switchport mode access
Router(config-if)#switchport access vlan 10
Router(config-if)#exit

VLANにIPを割り当てる

Router(config)#int vlan 10
Router(config-if)#ip add 172.16.10.254 255.255.255.0

※同じ要領で２つ目のVLANを作成する

VLAN Name                             Status    Ports
---- -------------------------------- --------- -------------------------------
1    default                          active    Fa4, Fa5, Fa6, Fa7, Fa8, Fa9
10   VLAN0010                         active    Fa2
20   VLAN0020                         active    Fa3

ルーティングを有効化

Switch(config)#ip routing

それぞれにパソコンを接続し疎通確認を行う。
