实验拓扑图

1，配置sw2交换机

<Huawei>sys[Huawei]sysname SW2[SW2]vlan batch 10 20  ##创建vlan10 20[SW2]int e0/0/2[SW2-Ethernet0/0/2]port link-type access   ##设置access[SW2-Ethernet0/0/2]port default vlan 10    ##将接口放到vlan中[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      ##设置trunk[SW2-Ethernet0/0/1]port trunk allow-pass vlan all   ##允许所有的vlan通过[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

2，配置sw3交换机（同sw2一样配置）

<Huawei>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

3，配置sw1三层交换机

<Huawei>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   ##三层交换连接路由的不能配置trunk[SW1-GigabitEthernet0/0/2]port default vlan 1000[SW1-GigabitEthernet0/0/2]un sh[SW1-GigabitEthernet0/0/2]q[SW1]int vlanif 10   ##进入逻辑接口[SW1-Vlanif10]ip add 192.168.10.1 24  ##设置网关[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  ##设置默认路由，向上默认，向下静态

4，配置R1路由

<Huawei>sys[Huawei]sysname R1[R1]int g0/0/0   ##设置接口的ip地址[R1-GigabitEthernet0/0/0]ip add 11.0.0.2 30[R1-GigabitEthernet0/0/0]un sh[R1-GigabitEthernet0/0/0]int loopback 0  ##进入回环接口，设置ip[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 ##设置静态路由[R1]ip route-static 192.168.20.0 24 11.0.0.1

5，测试全网互通性
