       本文档详细介绍了新租赁写字楼的网络规划,包括为财务部分配192.168.0.140/27网段,确保服务器IP不变,并按部门划分VLAN,如管理层、行政部、市场部等,每个VLAN配置了相应的IP范围和子掩码。同时,配置了核心交换机和路由器的VLAN、DHCP服务,确保各部门的网络连接和地址分配。

 

一、实验环境

 

公司最近新租赁了写字楼,领导要求一定要好好规划网络,整理IP地址

 

二、实验需求
1、财务部有几台服务器,IP地址不能变,分别是:

192.168.0.143
192.168.0.144
192.168.0.145
192.168.0.146

因此,我们需要给财务找个网段,把上面的IP包含进去,但是范围还不能太大。研究之后决定给财务:192.168.0.140/27 这个网段。

实际就是:

财务部IP范围:192.168.0.129192.168.0.158
子掩码是:255.255.255.224
网关:192.168.0.140

 

2、按照部门划分vlan,除了财务部20台终端左右,其他部门最多不超过50台。

 

三、SW核心交换机vlan配置

创建需要的vlan

un in en
vlan batch 11 12 13 14 15 16 99
q

将接口划分到相应的vlan

interface GigabitEthernet0/0/1
 port link-type access
 port default vlan 11
q

interface GigabitEthernet0/0/2
 port link-type access
 port default vlan 12
q

interface GigabitEthernet0/0/3
 port link-type access
 port default vlan 13
q

interface GigabitEthernet0/0/4
 port link-type access
 port default vlan 14
q

interface GigabitEthernet0/0/5
 port link-type access
 port default vlan 15
q

interface GigabitEthernet0/0/6
 port link-type access
 port default vlan 16
q

interface GigabitEthernet0/0/24
 port link-type access
 port default vlan 99
q

配置vlanIP

interface Vlanif11    #财务网段,不能变
ip address 192.168.0.1 255.255.255.0
q

interface Vlanif12
 ip address 192.168.12.1 255.255.255.192
q
 
interface Vlanif13
 ip address 192.168.13.1 255.255.255.192
q
 
interface Vlanif14
 ip address 192.168.14.1 255.255.255.192
q

interface Vlanif15
ip address 192.168.15.1 255.255.255.192
q

interface Vlanif16
ip address 192.168.16.1 255.255.255.192
q

interface Vlanif99    #上行链路
ip address 192.168.99.99 255.255.255.192
q

配置完,可以用下面的命令查看确认。

dis ip in b

四、R1路由器DHCP配置

开启DHCP

[R1]un in en
dhcp enable
interface GigabitEthernet0/0/2
 ip address 192.168.99.254 255.255.255.0 
 dhcp select global
 q

加入回执路由

ip route-static 0.0.0.0 0 192.168.99.99

创建各个vlan的地址池

vlan99不用创建,vlan99我们不开启DHCP

ip pool vlan11    #财务网段,不能变
 gateway-list 192.168.0.129 
 network 192.168.0.129 mask 255.255.255.224 
 dns-list 114.114.114.114
q

ip pool vlan12
 gateway-list 192.168.12.1 
 network 192.168.12.0 mask 255.255.255.192 
 dns-list 114.114.114.114
q

ip pool vlan13
 gateway-list 192.168.13.1 
 network 192.168.3.0 mask 255.255.255.192 
 dns-list 114.114.114.114
q

ip pool vlan14
 gateway-list 192.168.14.1 
 network 192.168.4.0 mask 255.255.255.192 
 dns-list 114.114.114.114
q
 
 ip pool vlan15
 gateway-list 192.168.15.1 
 network 192.168.5.0 mask 255.255.255.192 
 dns-list 114.114.114.114
q
 
ip pool vlan116
 gateway-list 192.168.16.1 
 network 192.168.6.0 mask 255.255.255.192 
 dns-list 114.114.114.114
q

配置完可以使用下面的命令查看一下有没有问题。

dis ip pool

五、SW1核心交换机上配置DHCP中继

dhcp enable

interface Vlanif11
dhcp select relay
dhcp relay server-ip 192.168.99.254
q

interface Vlanif12
dhcp select relay
dhcp relay server-ip 192.168.99.254
q

interface Vlanif13
dhcp select relay
dhcp relay server-ip 192.168.99.254
q

interface Vlanif14
dhcp select relay
dhcp relay server-ip 192.168.99.254
q

interface Vlanif15
dhcp select relay
dhcp relay server-ip 192.168.99.254
q

interface Vlanif16
dhcp select relay
dhcp relay server-ip 192.168.99.254
q
