一.七天酒店网络配置

要求

酒店共计9层

第一层前台接待4台 —— 使用8口交换机

第二层4台—— 使用8口交换机

第三层到第九层交换机，有20台电脑 —— 使用24口交换机

拓扑图

这里写图片描述

思路

  • 本题应该将各层电脑分成三个网络，分别是一层，二层和客房

  • 将它们的网络划分为 192.168.1.0 ， 192.168.2.0 ， 192.168.3.0

  • 将各分交换机的汇聚在一个交换机上，进行端口的子网划分

  • 开启对接路由器端口的trunk模式

  • 将路由器划虚拟分子网，实现联通

二.某互联网创业公司 公司网络规划及实施

业务规划

公司6个部门 技术部 财务部 人事部 产品部 设计部 销售部 

公司大厦为五层 其中二三四层分别有两个部门

每个部门之间不能互相通信 每个部门都能访问服务器区

网络规划

VLAN 共8个VLAN   6个部门各一个、DMZ区一个、一层接待一个

VLAN10 192.168.10.0/24 网关254

VLAN21 192.168.21.0/24 网关254

VLAN22 192.168.22.0/24 网关254

VLAN31 192.168.31.0/24 网关254

VLAN32 192.168.32.0/24 网关254

VLAN41 192.168.41.0/24 网关254

VLAN42 192.168.42.0/24 网关254

VLAN100 192.168.100.0/24 网关254



核心交换机和服务器放在五层机房内



核心交换机作为每个VLAN的网关并启用路由功能、vtp

实施

在核心交换机配置VLAN vtp 网关 链路聚合

在接入交换机划分VLAN

服务器搭建
拓扑结构

这里写图片描述

思路

1.设置VTP


en

conf t

vtp mode client

vtp domain aaa

vtp password PASSWORD

ex


en

conf t

vtp mode server

vtp domain aaa

vtp password PASSWORD

ex

2.在服务器中配置vlan


en

conf t

vlan 41

name jishu

3.打开trunk


show interfaces trunk

4.划分端口及对应子网

将端口划分到子网内

en
conf t
int f0/1
swi mo ac
swi ac vlan 21
int f0/2
swi ac vlan 22 
do show vlan

5.IP routing将交换机调至路由功能
6.进入vlan，配置网关


interface vlan 10

IP address

7.负载均衡


Switch(config-if-range)#channel-group 1 mode on

Switch(config-if-range)#ex

Switch(config)#port-channel load-balance dst-ip

所以，拓扑结构为：

图为某酒店的组网，AR1为酒店的出口设备，通过与运营PPPoE拨号实现访问外网。AC1通过配置实现对AP1-AP4的纳管以及无线配置的下发。可以看到客户端通过PPPoE获取到了100.1.1.254的ip地址。创建用户名为huawei、密码为huawei的账号。设置本设备为PPPoE的服务端，并且关联VT接口。指定该dialer口的dialer bundle。绑定dialer口的dialer bundle。步骤1：配置AC，实现AC纳管AP并下发配置。调用为客户端分配地址的地址池pool1。
