3.使用Pvlan
待续
4.三层交换机上,用VLAN间ACL
access-list 120 permit ip any 192.168.30.0 0.0.0.255
access-list 130 permit ip any 192.168.20.0 0.0.0.255
vlan access-map deny20-30 100
match ip add 120
action drop
exit
vlan filter deny20-30 vlan-list 20
vlan access-map deny30-20 101
match ip add 130
action drop
exit
vlan filter deny30-20 vlan-list 30
