Isolated: Communicates with only promiscuous ports.
Community: Communicates with the other members of the same community VLAN and all promiscuous ports.
Promiscuous: Communicates with all other ports in the same primary VLAN.
Description:
R5: Gateway 10.0.0.1
R1: simulate Switch1.
ConfigureFa0/9 as Promiscuous Port
Fa0/1-2 as Community Port
Fa0/3 as Isolated Port
R2,R3,R4 simulate Switch2, Switch3, Switch4
Purpose:
xp和win7-1属于相同团体vlan，可相互通信。
win7-2属于隔离vlan，只能和混杂端口Fa0/9通信。
所有主机可以和网关(R5 Fa0/0)通信。
主vlan：Vlan 100， 团体vlan：vlan 170 隔离vlan：vlan 200
