拓扑如下图所示：
具体配置:
SW1:
int vlan 10
ip-subnet-vlan 1 ip 192.168.1.0 255.255.255.0
int vlan 20
ip-subnet-vlan 1 ip 192.168.2.0 255.255.255.0
nterface Ethernet0/0/1
port link-type trunk
port trunk allow-pass vlan 2 to 4094
interface Ethernet0/0/2
port link-type hybrid
port hybrid untagged vlan 2 to 4094
ip-subnet-vlan enable
interface Ethernet0/0/3
port link-type hybrid
port hybrid untagged vlan 2 to 4094
ip-subnet-vlan enable
