三层网络拓扑

先配置核心交换机

1.先配置核心交换机(cure-switch)

sys
[Huawei]sysname cure-switch
[cure-switch]interface GigabitEthernet 0/0/0 
[cure-switch-GigabitEthernet0/0/0]port link-type trunk 
[cure-switch-GigabitEthernet0/0/0]port link-type dot1q-tunnel 

命令如下：
[cure-switch]display ip interface br
查看网络ip地址
sys  进入配置模式
[cure-switch]interface GigabitEthernet 0/0/0 
interface Ethernet0/0/0 指的是以太网端口0下面的子端口0
interface GigabitEthernet1/0/0 指千兆以太网接口 1/0/0表示机器号/槽位号/子接口号
[cure-switch-GigabitEthernet0/0/0]port link-type dot1q-tunnel 
封装协议
[cure-switch-GigabitEthernet0/0/0]port link-type trunk 
指定端口模式为trunk模式
dis th查看接口配置
[cure-switch-GigabitEthernet0/0/2]dis int brief 
查看接口的配置简略信息
[cure-switch-GigabitEthernet0/0/2]vlan 
交换机的端口工作模式一般可以分为三种：Access（普通模式），Multi（多vlan模式），
Trunk（中继模式）
设备和设备之间用trunk模式
设备和pc之间用access模式

[cure-switch]interface GigabitEthernet 0/0/1
[cure-switch-Ethernet0/0/1]port link-type trunk
[cure-switch-Ethernet0/0/1]port link-type dot1q-tunnel 
[cure-switch]interface GigabitEthernet 0/0/0
[cure-switch-Ethernet0/0/0]port
进入交换模式
[cure-switch-Ethernet0/0/0]port link-type trunk 
[cure-switch-Ethernet0/0/0]port link-type dot1q-tunnel
[cure-switch]vlan batch 10 20 30
[cure-switch]int vlan 10
进入vlan10
[cure-switch]int vlan 20
[cure-switch-Vlanif20]ip add 192.168.20.254 255.255.255.0
[cure-switch]int vlan 30
[cure-switch-Vlanif30]ip add 192.168.30.254 255.255.255.0
配置ip地址

2.配置二层交换机

sys
[Huawei]sysname sw1
[sw1]interface GigabitEthernet 0/0/2
[sw1-GigabitEthernet0/0/2]port link-type access
[sw1]int GigabitEthernet 0/0/1
[sw1-GigabitEthernet0/0/1]port link-type trunk 
[sw1-GigabitEthernet0/0/1]port link-type dot1q-tunnel 
[sw1]vlan 30
[sw1]interface GigabitEthernet 0/0/2
[sw1-GigabitEthernet0/0/2]port default vlan 30
把这个接口添加到vlan，30里

2.2.配置SW2

sys
[Huawei]sysname sw2
[sw2]interface GigabitEthernet 0/0/2
[sw2-GigabitEthernet0/0/2]port link-type access
[sw2]int GigabitEthernet 0/0/1
[sw2-GigabitEthernet0/0/1]port link-type trunk 
[sw2-GigabitEthernet0/0/1]port link-type dot1q-tunnel
[sw2]vlan 10
[sw2]interface GigabitEthernet 0/0/2
[sw2-GigabitEthernet0/0/2]port default vlan 10

2.3.配置SW3

sys 
[Huawei]sysname sw3
[sw3]interface GigabitEthernet 0/0/1
[sw3-GigabitEthernet0/0/1]port link-type access
[sw3-GigabitEthernet0/0/1]int GigabitEthernet 0/0/2
[sw3-GigabitEthernet0/0/2]port link-type trunk
[sw3-GigabitEthernet0/0/2]port link-type dot1q-tunnel
[sw3-GigabitEthernet0/0/2]vlan 20
[sw3-vlan30]interface GigabitEthernet 0/0/1
[sw3-GigabitEthernet0/0/1]port default vlan 20
