一 需求分析

本實驗的目的在于建立小型局域網(wǎng)。由于公司由財政部、人事部、科技部三個部門組成，分布在同一個交換機下。設(shè)計以下網(wǎng)絡(luò)：三個個部門使用兩臺交換機連接，然后連接到匯聚交換機，再通過路由器與外網(wǎng)以及其他部門網(wǎng)絡(luò)相連。為了控制網(wǎng)絡(luò)上的廣播風(fēng)暴，增加網(wǎng)絡(luò)的安全性，在交換機上需要設(shè)置VLAN，公司內(nèi)部使用動態(tài)路由OSPF協(xié)議，所有主機均可通過dhcp自動獲取ip地址。

二 規(guī)劃拓撲

• 劃分vlan：

• ip地址規(guī)劃：

• 匯聚交換機配置dhcp功能，員工無需手動配置ip

• 采用一個匯聚交換機，兩個二層交換機，匯聚交換機開啟dhcp服務(wù)，合理劃分vlan、利用trunk和access口

三 拓撲圖

四 實驗配置

4.1 二層交換機配置

無腦trunk和access就行了

LSW2：

[Huawei]vlan batch 10 20 30
[Huawei-Ethernet0/0/2]int e0/0/1
[Huawei-Ethernet0/0/1]port link-type trunk 
[Huawei-Ethernet0/0/1]port trunk allow-pass vlan all 
[Huawei-Ethernet0/0/2]int e0/0/2
[Huawei-Ethernet0/0/1]port link-type trunk 
[Huawei-Ethernet0/0/1]port trunk allow-pass vlan all 
[Huawei-Ethernet0/0/3]port link-type access   
[Huawei-Ethernet0/0/3]port default vlan 10
[Huawei-Ethernet0/0/4]port link-type access   
[Huawei-Ethernet0/0/4]port default vlan 20

LSW3：

[Huawei]vlan batch 10 20 30
[Huawei-Ethernet0/0/2]int e0/0/1
[Huawei-Ethernet0/0/1]port link-type trunk 
[Huawei-Ethernet0/0/1]port trunk allow-pass vlan all 
[Huawei-Ethernet0/0/1]int e0/0/2
[Huawei-Ethernet0/0/2]port link-type trunk 
[Huawei-Ethernet0/0/2]port trunk allow-pass vlan all 
[Huawei-Ethernet0/0/1]int e0/0/3
[Huawei-Ethernet0/0/3]port link-type access   
[Huawei-Ethernet0/0/3]port default vlan 10
[Huawei-Ethernet0/0/3]int e0/0/4
[Huawei-Ethernet0/0/4]port link-type access   
[Huawei-Ethernet0/0/4]port default vlan 20

LSW1:

[Huawei]vlan batch 10 20 30 99
[Huawei-GigabitEthernet0/0/2]int G0/0/1
[Huawei-GigabitEthernet0/0/2]port link-type access
[Huawei-GigabitEthernet0/0/2]port default vlan 99
[Huawei-GigabitEthernet0/0/1]int G0/0/2
[Huawei-GigabitEthernet0/0/2]port link-type trunk 
[Huawei-GigabitEthernet0/0/2]port trunk allow-pass vlan all 
[Huawei-GigabitEthernet0/0/2]int G0/0/3
[Huawei-GigabitEthernet0/0/3]port link-type trunk 
[Huawei-GigabitEthernet0/0/3]port trunk allow-pass vlan all 

4.2配置vlanif口

LSW1:

interface Vlanif10
 ip address 192.168.10.254 255.255.255.0
interface Vlanif20
 ip address 192.168.20.254 255.255.255.0
interface Vlanif30
 ip address 192.168.30.254 255.255.255.0

4.3配置dhcp服務(wù)

LSW1:

配置全局地址池

ip pool vlan10//配置全局地址池
 gateway-list 192.168.10.254
 network 192.168.10.0 mask 255.255.255.0
#
ip pool vlan20
 gateway-list 192.168.20.254
 network 192.168.20.0 mask 255.255.255.0
#
ip pool vlan30
 gateway-list 192.168.30.254
 network 192.168.30.0 mask 255.255.255.0
#

在vlanif口開啟開啟dhcp

interface Vlanif10
 ip address 192.168.10.254 255.255.255.0
 dhcp select global
#
interface Vlanif20
 ip address 192.168.20.254 255.255.255.0
 dhcp select global
#
interface Vlanif30
 ip address 192.168.30.254 255.255.255.0
 dhcp select global

4.4 公司內(nèi)用ospf內(nèi)部網(wǎng)關(guān)協(xié)議進行通信
