实验步骤

第一步:配置sw2交换机

sys
[Huawei]sysname SW2
[SW2]vlan batch 10 20
[SW2]int e0/0/2
[SW2-Ethernet0/0/2]port link-type access 
[SW2-Ethernet0/0/2]port default vlan 10
[SW2-Ethernet0/0/2]un sh
[SW2-Ethernet0/0/2]int e0/0/3
[SW2-Ethernet0/0/3]port link-type access
[SW2-Ethernet0/0/3]port default vlan 20
[SW2-Ethernet0/0/3]un sh
[SW2-Ethernet0/0/3]int e0/0/1
[SW2-Ethernet0/0/1]port link-type trunk 
[SW2-Ethernet0/0/1]port trunk allow-pass vlan all 
[SW2-Ethernet0/0/1]un sh
[SW2-Ethernet0/0/1]int g0/0/1
[SW2-GigabitEthernet0/0/1]port link-type trunk  
[SW2-GigabitEthernet0/0/1]port trunk allow-pass vlan all 
[SW2-GigabitEthernet0/0/1]un sh

第二步:配置sw3交换机

sys
[Huawei]sysname SW3 
[SW3]vlan batch 10 20
[SW3]int e0/0/2
[SW3-Ethernet0/0/2]port link-type access 
[SW3-Ethernet0/0/2]port default vlan 10
[SW3-Ethernet0/0/2]un sh
[SW3-Ethernet0/0/2]int e0/0/3
[SW3-Ethernet0/0/3]port link-type access    
[SW3-Ethernet0/0/3]port default vlan 20
[SW3-Ethernet0/0/3]un sh
[SW3-Ethernet0/0/3]int e0/0/1
[SW3-Ethernet0/0/1]port link-type trunk 
[SW3-Ethernet0/0/1]port trunk allow-pass vlan all 
[SW3-Ethernet0/0/1]un sh

第三步:配置sw1三层交换机(向上指默认路由,向下指静态路由)

sys
[Huawei]sysname SW1
[SW1]vlan batch 10 20 1000
[SW1]int g0/0/1
[SW1-GigabitEthernet0/0/1]port link-type trunk 
[SW1-GigabitEthernet0/0/1]port trunk allow-pass vlan all 
[SW1-GigabitEthernet0/0/1]un sh
[SW1-GigabitEthernet0/0/1]int g0/0/2
[SW1-GigabitEthernet0/0/2]port link-type access
[SW1-GigabitEthernet0/0/2]port default vlan 1000
[SW1-GigabitEthernet0/0/2]un sh
[SW1-GigabitEthernet0/0/2]quit
[SW1]int vlanif 10
[SW1-Vlanif10]ip add 192.168.10.1 24
[SW1-Vlanif10]int vlanif 20
[SW1-Vlanif20]ip add 192.168.20.1 24
[SW1]int vlanif 1000
[SW1-Vlanif1000]ip add 11.0.0.1 30
[SW1-Vlanif1000]q
[SW1]ip route-static 0.0.0.0 0.0.0.0 11.0.0.2

第四步:配置R1路由器

sys
[Huawei]sysname R1
[R1]int g0/0/0
[R1-GigabitEthernet0/0/0]ip add 11.0.0.2 30
[R1-GigabitEthernet0/0/0]un sh
[R1-GigabitEthernet0/0/0]int loopback 0
[R1-LoopBack0]ip add 1.1.1.1 30
[R1-LoopBack0]q
[R1]ip route-static 192.168.10.0 24 11.0.0.1
[R1]ip route-static 192.168.20.0 24 11.0.0.1

第五步:配置PC端IP地址及网关

第六步:测试全网互联互通
