ensp-DHCP综合实验笔记

DHCP综合实验

实验目的

DHCP服务器属于vlan 88
市场部、运营部、设计部分别属于 vlan 10 /20 /30
规划每个部门的网关
PC端自动获取IP地址参数
每个vlan 的网段为192.168.xx.0/24（XX是vlan号）
所有PC之间互通

老师效果图

配置思路

DHCP客户端
DHCP服务器
中继（网关接口）
客户端和中继之间的交换网络
中继与服务器之间的路由网络
验证互通

实验步骤

1.搭建框架

2.配置PC1 - PC6 IP为DHCP

3.对ar1进行配置

开启DHCP全局，配置IP池  默认路由
sys
sys DHCP
un t m
dhcp enable
in g0/0/1
ip add 192.168.88.1 24
dhcp select global
ip policy-based-route
ip pool vlan-10
network 192.168.10.0 mask 24
gateway-list 192.168.10.254 
dns-list 8.8.8.8
ip pool vlan-20
network 192.168.20.0 mask 24    
gateway-list 192.168.20.254
dns-list 8.8.8.8
ip pool vlan-30
network 192.168.30.0 mask 24
gateway-list 192.168.30.254
dns-list 8.8.8.8
ip route-static 0.0.0.0 0 192.168.88.254

4.配置交换机1 DHCP中继

开启DHCP 建立vlan 10 20 30 88 配置聚合链路 ip地址
sys
sys SW1
un in en 
dhcp enable
vlan batch 10 20 30 88 12
in g0/0/1
port link-type access
port default vlan 88
port-group group-member g0/0/2 g0/0/3 g0/0/4
port link-type trunk
port trunk allow-pass vlan all  
q
interface Vlanif 10
ip add 192.168.10.254 24
dhcp select relay 
dhcp relay server-ip 192.168.88.1

interface Vlanif 30
ip add 192.168.30.254 24
dhcp select relay 
dhcp relay server-ip 192.168.88.1

interface Vlanif 12
ip add 192.168.12.1 24

interface Vlanif 88
ip add 192.168.88.254 24

q
ip route-static 192.168.20.0 24 192.168.12.2

5.配置交换机2 SW2

sys
sys SW2
un in en 
dhcp enable
vlan batch 10 20 30 12
port-group group-member g0/0/2 g0/0/23
port link-type trunk
port trunk allow-pass vlan all
q
in g0/0/11
port link-type access
port default vlan 10
in g0/0/12
port link-type access
port default vlan 20
q
in Vlanif 20
ip add 192.168.20.254 24
dhcp select relay 
dhcp relay server-ip 192.168.88.1

in Vlanif 12
ip add 192.168.12.2 24
q
ip route-static 192.168.88.0 24 192.168.12.1
ip route-static 192.168.10.0 24 192.168.12.1
ip route-static 192.168.30.0 24 192.168.12.1
至于为什么是LSW5 而不是LSW2，那是因为我配错了中间不知道哪里，排错排了一个小时未果，就删了再来了一遍，直接通了，玄学！

6.配置交换机3

un t m
sys
sys SW3
vlan batch 10 20 30
port-group group-member g0/0/3 g0/0/23 g 0/0/24
port link-type trunk
port trunk allow-pass vlan all
q
in g0/0/13
port link-type access
port default vlan 10
in g0/0/14
port link-type access
port default vlan 30

7.配置交换机4

un t m 
sys
sys SW4
vlan batch 10 20 30
port-group group-member g0/0/4 g0/0/24
port link-type trunk
port trunk allow-pass vlan all
q
in g0/0/15
port link-type access
port default vlan 20
in g0/0/16
port link-type access
port default vlan 30
