DHCP&OSPF combined experimental demonstration (Huawei routing and switching equipment configuration)

一、背景介绍

该实验通过DHCP与OSPFThe combination simulates small and medium-sized network deployment environments.

二、The purpose of small and medium network experiments

PC1和PC2实现IPDynamic management of addresses;

Can and egress routerRouter连通.

三、实验拓扑

四、实验配置

（1）PC1,PC2选择为DHCP自动获取.

（2）DHCP配置——接入交换机acsw配置

<Huawei>sys

#进入系统视图

[Huawei]sysname acsw

#修改交换机名称为acsw

[acsw]vlan batch 10 20

#创建vlan10和20

[acsw]un in en

#关闭日志提示

[acsw]interface g0/0/1

#进入接口

[acsw-GigabitEthernet0/0/1]port link-type access

#接口配成access模式

[acsw-GigabitEthernet0/0/1]port default vlan 10

#配置接口VLAN 10

[acsw-GigabitEthernet0/0/1]int g0/0/2

[acsw-GigabitEthernet0/0/2]port link-type access

[acsw-GigabitEthernet0/0/2]port default vlan 20

[acsw-GigabitEthernet0/0/2]q

[acsw]int g0/0/3

[acsw-GigabitEthernet0/0/3]port link-type trunk  

#接口配成trunk模式

[acsw-GigabitEthernet0/0/3]port trunk allow-pass vlan all

#允许所有vlan通过

[acsw-GigabitEthernet0/0/3]q

#退出

（3）DHCP——核心交换机coresw配置

<Huawei>system-view  

[Huawei]sysname coresw

[coresw]un in en

[coresw]vlan batch 10 20 30

[coresw]interface g0/0/3

[coresw-GigabitEthernet0/0/3]port link-type trunk  

[coresw-GigabitEthernet0/0/3]port trunk allow-pass vlan all

[coresw-GigabitEthernet0/0/3]q

[coresw]int Vlanif 10

[coresw-Vlanif10]ip add 192.168.10.254 24

#配置vlan10的网关

[coresw-Vlanif10]int Vlanif 20

[coresw-Vlanif20]ip add 192.168.20.254 24

#配置vlan20的网关

[coresw-Vlanif20]q

[coresw]dhcp enable  

#开启DHCP功能

[coresw]ip pool vlan10

#创建地址池名字是vlan10

[coresw-ip-pool-vlan10]network 192.168.10.0 mask 24

#地址池下发网段

[coresw-ip-pool-vlan10]gateway-list 192.168.10.254

#地址池下发网关

[coresw-ip-pool-vlan10]dns-list 8.8.8.8

#地址池下发dns地址

[coresw-ip-pool-vlan10]excluded-ip-address 192.168.10.2 192.168.10.253

#地址不下发范围

[coresw-ip-pool-vlan10]lease day 3

 #租期为3天

[coresw-ip-pool-vlan10]q

[coresw]int Vlanif 10

[coresw-Vlanif10]dhcp select global  

[coresw]ip pool vlan20

[coresw-ip-pool-vlan20]network 192.168.20.0 mask 24

[coresw-ip-pool-vlan20]gateway-list 192.168.20.254

[coresw-ip-pool-vlan20]dns-list 114.114.114.114

[coresw-ip-pool-vlan20]excluded-ip-address 192.168.20.2 192.168.20.253

[coresw-ip-pool-vlan20]q

[coresw]int Vlanif 20

[coresw-Vlanif20]dhcp select global  

[coresw-Vlanif20]q

#DHCP功能配置完成,下面开始配置OSFP

[coresw]ospf 1

#配置OSPF

[coresw-ospf-1]area 0

#Configured as a region0

[coresw-ospf-1-area-0.0.0.0]network 192.168.10.0 0.0.0.255

#宣告网段
