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
下面是PC1-PC6的截图
下面是PC1 ping通PC2-PC6的截图
到这里这个实验就结束了!,下面是最终成果图

I wanted to compose you a bit of remark to be able to say thank you as before for those lovely basics you have shared at this time. This is certainly surprisingly open-handed of people like you in giving unhampered what a lot of folks could have marketed for an e book in order to make some dough on their own, notably now that you could have tried it in the event you decided. Those things likewise acted as a fantastic way to realize that some people have the identical dream much like mine to understand way more in regard to this matter. Certainly there are some more enjoyable sessions up front for those who looked over your blog. Phil Holzman
