**配置思路：**

> 1、先配置路由加第一层交换机，给他弄通
> 
> 2、在配置第二层和第三层交换机
> 
> 3、配置stp备份
> 
> 4、配置dhcp
> 
> 5、跑通全网

**目录**

1、路由+交换机配置

2、交换机与交换机之间配置

LW1、LW2相同配置

绑定链路

修改干道模式

查验：dis port vlan active

配置vlan1 vlan2 的地址

LW1 LW2互为备份

网关冗余

LW3/LW4

修改trunk干道

修改电脑access口

3、 DHCP地址池配置

## 1、路由+交换机配置 ##

**R3**

[Huawei]sys r3
    [r3]int g 0/0/0
    [r3-GigabitEthernet0/0/0]ip add 34.1.1.1 24
    [r3]int g 0/0/1
    [r3-GigabitEthernet0/0/1]ip add 172.16.1.2 24
    [r3-GigabitEthernet0/0/1]int g 0/0/2
    [r3-GigabitEthernet0/0/2]ip add 172.16.2.2 24
    
    [r3]rip 1        //启动rip协议学习路由
    [r3-rip-1]v 2
    [r3-rip-1]network 172.16.0.0

**SW1**

[Huawei]sys sw1
    
    * 注：因为华为不支持直接在接口配置ip地址，所以创建一个不着边的vlan，在svi99中写地址，算是曲线救国的方法。
    [sw1]vlan 99 
    [sw1-GigabitEthernet0/0/1]port link-type access     //修改接口
    [sw1-GigabitEthernet0/0/1]port default vlan 99    //引入vlan99
    [sw1]int Vlanif 99        //进入svi虚拟接口中
    [sw1-Vlanif99]ip address 172.16.1.1 24
    
    [sw1]rip 1        //开启rip协议
    [sw1-rip-1]v 2	
    [sw1-rip-1]network 172.16.0.0

**SW2**

[sw2]vlan 99
    [sw2-GigabitEthernet0/0/1]port link-type access 
    [sw2-GigabitEthernet0/0/1]port default vlan 99
    [sw2]int Vlanif 99
    [sw2-Vlanif99]ip add 172.16.2.1 24
    
    [sw2]rip 1
    [sw2-rip-1]v 2
    [sw2-rip-1]network 172.16.0.0

R3 ping 可通 一下直连测试一下**曲线救国的 OK**

## 2、交换机与交换机之间配置 ##

### **LW1、LW2相同配置** ###

#### **绑定链路** ####

> \[sw1\]interface Eth-Trunk 0 创建通道接口
> 
> \[sw1-Eth-Trunk0\]q
> 
> \[sw1\]interface GigabitEthernet 0/0/1 将物理接口加入到通道内
> 
> \[sw1-GigabitEthernet0/0/1\]eth-trunk 0
> 
> \[sw1-GigabitEthernet0/0/1\]int g0/0/2
> 
> \[sw1-GigabitEthernet0/0/2\]eth-trunk 0

####  ####

#### **修改干道模式** ####

> \[sw1\]port-group group-member g 0/0/4 to g 0/0/5
> 
> \[sw1-port-group\]port link-type trunk  
> \[sw1-GigabitEthernet0/0/4\]port link-type trunk  
> \[sw1-GigabitEthernet0/0/5\]port link-type trunk
> 
> \[sw1-port-group\]port trunk allow-pass vlan all  
> \[sw1-GigabitEthernet0/0/4\]port trunk allow-pass vlan all  
> \[sw1-GigabitEthernet0/0/5\]port trunk allow-pass vlan all

#### 查验：dis port vlan active ####

#### **配置vlan1 vlan2 的地址** ####

> \[sw2\]int Vlanif 2
> 
> \[sw2-Vlanif2\]ip add 172.16.4.2 24
> 
> \[sw2\]int Vlanif 1
> 
> \[sw2-Vlanif1\]ip add 172.16.3.2 24

### ![df8956ce2d264f8c9cb87fc80cef4c91.png][] ###

####  **LW1 LW2互为备份** ####

**配置交换机1/2、3/4、都要在同一个生成树之内**

[sw1]stp region-configuration  //启动生成树协议
    [sw1-mst-region]region-name a	//协议名字a
    [sw1-mst-region]instance 1 vlan 1    //配置组1，把vlan1放进去
    [sw1-mst-region]instance 2 vlan 2    //配置组2，把vlan2放进去
    [sw1-mst-region]active region-configuration     //启动该协议

**更改根的主从**

[sw2]stp  instance 1 root secondary     //当组1的备份根
    [sw2]stp instance 2 root primary     //当组2的主根

**\[sw1\]dis stp brief ———— 查看stp表**

### ![bb34bfce281f4a44830029ddd5f94ef0.png][] ###

#### **网关冗余** ####

[sw1]int vlanif 1
    [sw1-Vlanif1]vrrp vrid 1 virtual-ip 172.16.3.250    //虚拟网关
    [sw1-Vlanif1]vrrp vrid 1 priority 101    //修改优先级，默认是100

从设备不用修改优先级

[sw2] int Vlanif  1
    
    [sw2-Vlanif1]vrrp vrid 1 virtual-ip 172.16.3.250

查验：\[sw2\]dis vrrp interface Vlanif 1

![df777f1f94cb4cc492355136caeefe02.png][]

### **LW3/LW4**  ###

#### **修改trunk干道** ####

> \[sw3\]port-group group-member e 0/0/1 e 0/0/4
> 
> \[sw3-Ethernet0/0/4\]port link-type trunk
> 
> \[sw3-port-group\]port trunk allow-pass vlan all

#### **修改电脑access口** ####

> \[sw3\]vlan 2
> 
> \[sw3\]int e 0/0/2
> 
> \[sw3-Ethernet0/0/2\]port link-type access  
> \[sw3-Ethernet0/0/2\]port default vlan 1
> 
> \[sw3\]int e 0/0/3
> 
> \[sw3-Ethernet0/0/3\]port link-type access
> 
> \[sw3-Ethernet0/0/3\]port default vlan 2

##  **3、 DHCP地址池配置**  ##

**sw2**

> \[sw2\]int vlan 1  
> \[sw2-Vlanif1\]dhcp select global  
> \[sw2-Vlanif1\]int vlan 2  
> \[sw2-Vlanif2\]dhcp select global
