18 周实训作业

注：分支要求详细配置，简化配置，期末见 <h.dayi.ink> cmd因版本过于乱，临时不再维护

版本0.9

排版比较乱，建议直接下下来，直接看running-config

周四要求和作业

要求：内网

某公司企业内网，内网当中存在四个vlan ，分别为vlan10 vlan20 vlan30 vlan100

财务部是vlan10，并命名为caiwu
技术部是vlan20,并命名为jishu
管理部门为vlan30，并命名为guanli
内网服务器内网HTTP-SERVER单独位于vlan100，vlan名称为fuwuqi。
配置基本网络：
1）财务部的网段是192.168.1.0/24，网关为192.168.1.254
2）技术部的网段为192.168.2.0/24，网关为192.168.2.254
3）管理部的网段为192.168.3.0/24，网关为192.168.3.254
4）服务器的网段为172.16.1.0/24，网关为172.16.1.254
5）R1和SW1之间互联的地址为192.168.10.0/30的地址
现在要求所有的网关都在内网核心交换机SW1上，使用svi接口充当网关
实现内网所有PC和服务器之间的互联
由于内网员工对于计算机的使用能力较差，因此，针对财务部，技术部和管理部的终端而言，需要通过DHCP的方式自动获取IP地址（需要排除每个网段1-100的地址作为保留使用，从101开始获取），而服务器的地址由于需要固定访问，所以通过手动静态配置IP地址。（dhcp的server位于出口路由器R1上，使用dhcp的中继完成最终地址的获取）
允许内网管理部门的员工通过telnet管理内网的路由器和核心交换机，其他部门不允许通过telnet管理路由器和交换机。（要配置telnet管理内网设备）

要求：公网

公网部分

R1和R2之间采用100.1.1.0/24网段，R2和R3之间采用124.126.100.0/24网段地址，R3和R4之间采用202.96.137.0/24网段地址，R3和外网HTTP-SERVER以及公网PC之间，采用124.126.200.0/24网段地址。（外网HTTP-SERVER和公网PC的网关为124.126.200.254）
为了保证公网之间能够通信，R1、R2、R3之间采用ospf动态路由协议进行通信
公网PC可以通过R1的8080端口访问到内网HTTP-SERVER的80端口的http业务
现在有一台公网服务器HTTP-SERVER，地址为124.126.200.10/24，现在需要内网用户能够访问到该公网服务器。（R1和R2之间使用124.126.100.0/24网段）
有一台公网的DNS-SERVER，地址为113.100.2.56/24，网关为113.100.2.1/24，我们最终想要通过访问www.shixun.com这个域名访问到公网http-server，并且查看首页的a small page，内容显示为：welcome to study our course!

要求：分支

内网PC7和PC8分别位于vlan70和vlan80这两个vlan当中
PC7和PC8的网关分别为192.168.70.254 192.168.80.254，且网关位于R4路由器上
PC7和PC8也要能够访问外网（测试访问公网HTTP-SERVER）

拓扑图

最后的拓扑图如下：

VLAN添加和配置

要求如下：VLAN配置要求

某公司企业内网中存在四个VLAN,具体配置如下:

VLAN ID	名称	部门/用途
10	caiwu	财务部
20	jishu	技术部
30	guanli	管理部门
100	fuwuqi	内网服务器(HTTP-SERVER)

core(config)#vtp mode server
  Device mode already VTP SERVER.
core(config)#vtp domain crazy-friday
  Changing VTP domain name from NULL to crazy-friday
core(config)#vtp password crazy
  Setting device VLAN database password to crazy

核心交换机：配置VLAN地址

要求

2、配置基本网络：
1）财务部的网段是192.168.1.0/24，网关为192.168.1.254
2）技术部的网段为192.168.2.0/24，网关为192.168.2.254

5）R1和SW1之间互联的地址为192.168.10.0/30的地址

配置

添加4个vlan，并且配置IP地址。

core(config)#int vlan 10
core(config-if)#ip addr 192.168.1.254 255.255.255.0
core(config-if)#no shut

core(config-if)#int vlan 20
core(config-if)#ip addr 192.168.2.254 255.255.255.0
core(config-if)#no shut

core(config-if)#int vlan 30
core(config-if)#ip addr 192.168.3.254 255.255.255.0
core(config-if)#no shut

core(config-if)#int vlan 100
core(config-if)#ip addr 172.16.1.254 255.255.255.0
core(config-if)#no shut

当前接口状态和IP配置概要

物理接口状态：

FastEthernet0/1 到 FastEthernet0/4: 启用且运行中（up/up）
FastEthernet0/5: 物理连接断开（down/down）
GigabitEthernet0/1 和 GigabitEthernet0/2: 物理连接断开（down/down）

VLAN ID	IP地址	状态
1	未分配	管理性关闭
10	192.168.1.254	启用但协议层关闭
20	192.168.2.254	启用但协议层关闭
30	192.168.3.254	启用但协议层关闭
100	172.16.1.254	启用但协议层关闭

公司内网：3、现在要求所有的网关都在内网核心交换机SW1上，使用svi接口充当网关

SW1上开启三层路由功能

core#conf t
Enter configuration commands, one per line.  End with CNTL/Z.
core(config)#ip routing

公司内网：配置子交换机的VLAN同步：

财务部交换机

Switch>en
Switch#conf t
Enter configuration commands, one per line.  End with CNTL/Z.
Switch(config)#vtp mode client
Setting device to VTP CLIENT mode.
Switch(config)#vtp domain crazy-friday
Changing VTP domain name from NULL to crazy-friday
Switch(config)#vtp password crazy
Setting device VLAN database password to crazy

Switch(config)#hostname finance-sw
finance-sw(config)#int fa0/4
finance-sw(config-if)#switchport mode trunk

可以看到VLAN数据库已经成功同步

划分VLAN接口：

将全部接口划分到VLAN:

finance-sw(config-if)#int range fa0/1,fa0/2,fa0/3,fa0/5-24
finance-sw(config-if-range)#sw mode access 
finance-sw(config-if-range)#sw ac vlan 10

R1和R2之间采用100.1.1.0/24网段，R2和R3之间采用124.126.100.0/24网段地址，R3和R4之间采用202.96.137.0/24网段地址，R3和外网HTTP-SERVER以及公网PC之间，采用124.126.200.0/24网段地址。（外网HTTP-SERVER和公网PC的网关为124.126.200.254）
为了保证公网之间能够通信，R1、R2、R3之间采用ospf动态路由协议进行通信
公网PC可以通过R1的8080端口访问到内网HTTP-SERVER的80端口的http业务
现在有一台公网服务器HTTP-SERVER，地址为124.126.200.10/24，现在需要内网用户能够访问到该公网服务器。（R1和R2之间使用124.126.100.0/24网段）
有一台公网的DNS-SERVER，地址为113.100.2.56/24，网关为113.100.2.1/24，我们最终想要通过访问www.shixun.com这个域名访问到公网http-server，并且查看首页的a small page，内容显示为：welcome to study our course!

公网部分：3、公网PC可以通过R1的8080端口访问到内网HTTP-SERVER的80端口的http业务

内网访问服务器(172.16.1.10/24)，可以正常访问

R1配置路由

r1(config)#ip route 172.16.1.0 255.255.255.0 192.168.10.2

路由可以ping通内网服务器：

配置NAT：

r1(config)#int g0/0
r1(config-if)#ip nat inside
r1(config-if)#int g0/1
r1(config-if)#ip nat outside
r1(config)#ip nat inside source static tcp 172.16.1.10 80 100.1.1.1 8080

测试访问：

公网PC:

子网掩码:255.255.255.0
默认网关:124.126.200.254
DNS服务器：113.100.2.56

可以正常访问：

公网部分：4、现在有一台公网服务器HTTP-SERVER，地址为124.126.200.10/24，现在需要内网用户能够访问到该公网服务器。（R1和R2之间使用124.126.100.0/24网段）

（R1和R2之间使用124.126.100.0/24网段）此句话忽略。

IP配置：
IP地址:124.126.200.10
子网掩码:255.255.255.0
默认网关:124.126.200.254

r1(config)#access-list 10 permit 192.168.0.0 0.0.255.255
r1(config)#ip nat inside source list 10 interface g0/1 overload

可以正常访问啦！

公网部分：5、有一台公网的DNS-SERVER，地址为113.100.2.56/24，网关为113.100.2.1/24，我们最终想要通过访问www.shixun.com这个域名访问到公网http-server，并且查看首页的a small page，内容显示为：welcome to study our course!

18 周实训作业

文件

周四要求和作业

要求：内网

要求：公网

要求：分支

拓扑图

VLAN添加和配置

要求如下：VLAN配置要求

核心交换机：建立VLAN

核心交换机：配置完的VLAN信息：

核心交换机：配置VLAN分发，VTP服务器

核心交换机：配置VLAN地址

要求

配置

当前接口状态和IP配置概要

公司内网：3、现在要求所有的网关都在内网核心交换机SW1上，使用svi接口充当网关

公司内网：配置子交换机的VLAN同步：

财务部交换机

划分VLAN接口：

公司内网：管理部交换机

公司内网：技术部交换机

公司内网：服务器交换机

公司内网：服务器IP配置

公司内网： 2.5： 5）R1和SW1之间互联的地址为192.168.10.0/30的地址

核心交换机：

路由器

公司内网：4、实现内网所有PC和服务器之间的互联

允许trunk VLANIP互通

核心交换机：

使用服务器进行测试

ping：172.16.1.254

ping 192.168.1.254

ping 192.168.2.254

ping 192.168.3.254

ping 192.168.1.10

公司内网：5、由于内网员工对于计算机的使用能力较差，DHCP服务器

出口路由器

DHCP中继

测试：

公司内网：6、允许内网管理部门的员工通过telnet管理内网的路由器和核心交换机，其他部门不允许通过telnet管理路由器和交换机。（要配置telnet管理内网设备）

新建VLAN500用于管理，并配置ACL表

公网部分：要求

公网部分：1、IP配置

R1-IP：

R2-IP：

R3:

R4:

公网部分：3、公网PC可以通过R1的8080端口访问到内网HTTP-SERVER的80端口的http业务

公网部分：4、现在有一台公网服务器HTTP-SERVER，地址为124.126.200.10/24，现在需要内网用户能够访问到该公网服务器。（R1和R2之间使用124.126.100.0/24网段）

公网部分：5、有一台公网的DNS-SERVER，地址为113.100.2.56/24，网关为113.100.2.1/24，我们最终想要通过访问www.shixun.com这个域名访问到公网http-server，并且查看首页的a small page，内容显示为：welcome to study our course!

R2:

配置DNS服务器：

配置域名：

测试访问：

HTML内容

index.html

a_small_page.html

效果

分支：

分支：1、内网PC7和PC8分别位于vlan70和vlan80这两个vlan当中

分支：2、PC7和PC8的网关分别为192.168.70.254 192.168.80.254，且网关位于R4路由器上

分支：3、PC7和PC8也要能够访问外网（测试访问公网HTTP-SERVER）
