1. 配置各接口所属VLAN
[LSW1]vlan batch 10 20 30
[LSW1-GigabitEthernet0/0/1]port link-type access
[LSW1-GigabitEthernet0/0/1]port default vlan 10
[LSW1-GigabitEthernet0/0/2]port link-type trunk
[LSW1-GigabitEthernet0/0/2]port trunk allow-pass vlan 10 20
[LSW1-GigabitEthernet0/0/3]port link-type trunk
[LSW1-GigabitEthernet0/0/3]port trunk allow-pass vlan 10 30
[LSW2]vlan batch 10 20
[LSW2-GigabitEthernet0/0/2]port link-type access
[LSW2-GigabitEthernet0/0/2]port default vlan 20
[LSW2-GigabitEthernet0/0/1]port link-type trunk
[LSW2-GigabitEthernet0/0/1]port trunk allow-pass vlan 10 20
[LSW3]vlan batch 10 30
[LSW3-GigabitEthernet0/0/3]port link-type access
[LSW3-GigabitEthernet0/0/3]port default vlan 30
[LSW3-GigabitEthernet0/0/1]port link-type trunk
[LSW3-GigabitEthernet0/0/1]port trunk allow-pass vlan 10 30
2. 配置各VLANIF接口的IP地址
[LSW1-Vlanif10]ip add 10.1.1.1 24
[LSW1-Vlanif20]ip add 10.1.2.1 24
[LSW1-Vlanif30]ip add 10.1.3.1 24
[LSW2-Vlanif10]ip add 10.1.1.2 24
[LSW2-Vlanif20]ip add 10.1.2.2 24
[LSW3-Vlanif10]ip add 10.1.1.3 24
[LSW3-Vlanif30]ip add 10.1.3.3 24
3. 配置PC
4. 配置静态路由
[LSW1]ip route-static 10.1.3.0 24 10.1.1.3
[LSW1]ip route-static 10.1.2.0 24 10.1.1.2
[LSW2]ip route-static 0.0.0.0 0.0.0.0 10.1.2.1
[LSW3]ip route-static 0.0.0.0 0.0.0.0 10.1.3.1
5. 验证配置
