Cisco基础(六)：配置目前网络环境、项目阶段练习
一、配置目前网络环境
目标：
一家新创建的IT公司，公司位于北京有80多台服务器
目前网络环境使用技术，通过端口映射技术将web服务器发布给Internet：
- 三层交换：汇聚接入层交换机
- 默认路由：实现到互联网数以万计网络访问的简化配置
- 静态路由：实现公司内部网络互通
- NAT端口映射：实现企业内部Web服务器的发布
方案：
通过端口映射技术将web服务器发布给Internet，公司现有网络环境拓扑如下图所示：
现有网络连接说明如下表所示：
步骤：
步骤一：根据表-1为设备配置IP地址，并为三层交换机开启路由功能
1）MS1配置vlan1与f0/1接口的IP地址并开启路由功能
Switch(config)#hostname MS1
MS1(config)#ip routing
MS1(config)#interface vlan 1
MS1(config-if)#ip address 192.168.1.252 255.255.255.0
MS1(config-if)#no shutdown
MS1(config-if)#exit
MS1(config-if)#interface fastEthernet 0/1
MS1(config-if)#no switchport
MS1(config-if)#ip address 192.168.2.1 255.255.255.0
MS1(config-if)#no shutdown
步骤二：为路由器配置IP地址，添加接口模块
1）为路由器添加接口模块并进入路由器接口配置IP地址
Router(config)#hostname R1
R1(config)#interface fastEthernet 0/0
R1(config-if)#ip address 192.168.2.2 255.255.255.0
R1(config-if)#no shutdown
R1(config-if)#exit
R1(config)#interface fastEthernet 1/0
R1(config-if)#ip address 61.159.62.129 255.255.255.248
R1(config-if)#no shutdown
步骤三：配置MS1和路由器的静态路由
MS1(config-if)#ip route 0.0.0.0 0.0.0.0 192.168.2.2
R1(config)#ip route 192.168.1.0 255.255.255.0 192.168.2.1
步骤四：测试server1与R1接口IP的连通性

步骤五：R1配置端口映射
R1(config)#ip nat inside source static tcp 192.168.1.8 80 61.159.62.131 80
R1(config)#interface fastEthernet 0/0
R1(config-if)#ip nat inside
R1(config)#interface f1/0
R1(config-if)#ip nat outside
步骤六：在PC7上查看是映射结果，如下图所示
二、项目阶段练习
目标：
现有网络问题分析：
- 接入层交换机只与同一个三层交换机相连，存在单点故障而影响网络通信。
- 互联网连接单一服务商
现有网络需求：
- 随着企业发展，为了保证网络的高可用性，需要使用很多的冗余技术。
- 保证局域网络不会因为线路故障而导致的网络故障。
- 保证客户端机器不会因为使用单一网关而出现的单点失败。
- 保证到互联网的高可用接入使用冗余互联网连接。
- 提高网络链路带宽。
方案：
基于项目的需求，需要用到如下技术：
- STP：解决二层环路带来的广播风暴并链路冗余问题
- 以太网通道：提高网络链路带宽
- RIP路由协议：实现网络路径的自动学习
- HSRP：实现网关冗余
重新规划后的网络拓扑如下图：
重新规划后网络连接说明如下表所示：
步骤：
步骤一：静态路由升级动态路由。
1）R1删除静态路由并配置rip
R1(config)#no ip route 192.168.1.0 255.255.255.0 192.168.2.1
R1(config)#router rip
R1(config-router)#version 2
R1(config-router)#no auto-summary
R1(config-router)#network 192.168.2.0
R1(config-router)#default-information originate
2）MS1上删除静态路由并配置rip
MS1(config)#no ip route 0.0.0.0 0.0.0.0 192.168.2.2
MS1(config)#router rip
MS1(config-router)#version 2
MS1(config-router)#no auto-summary
MS1(config-router)#network 192.168.1.0
MS1(config-router)#network 192.168.2.0
3）在MS1上查看路由表
MS1#show ip route
Codes: C - connected, S - static, I - IGRP, R - RIP, M - mobile, B - BGP
D - EIGRP, EX - EIGRP external, O - OSPF, IA - OSPF inter area
N1 - OSPF NSSA external type 1, N2 - OSPF NSSA external type 2
E1 - OSPF external type 1, E2 - OSPF external type 2, E - EGP
i - IS-IS, L1 - IS-IS level-1, L2 - IS-IS level-2, ia - IS-IS inter area
* - candidate default, U - per-user static route, o - ODR
P - periodic downloaded static route
Gateway of last resort is 192.168.2.2 to network 0.0.0.0
C 192.168.1.0/24 is directly connected, Vlan1
C 192.168.2.0/24 is directly connected, FastEthernet0/1
R* 0.0.0.0/0 [120/1] via 192.168.2.2, 00:00:01, FastEthernet0/1
步骤二：配置SW1、SW2、SW3、SW4与MS1的接口为Trunk模式并做以太网通道。

5）关闭MS1
MS1(config)#interface range fastEthernet 0/1-24
MS1(config-if-range)#shutdown
6）在外网测试是否可以访问web服务器如下图所示
步骤八：在R2上配置端口映射
1）在R2上配置端口映射，指定NAT进口
R2(config)#ip nat inside source static tcp 192.168.1.8 80 61.159.62.131 80
R2(config)#interface fastEthernet 0/0
R2(config-if)#ip nat inside
R2(config-if)#exit
R2(config)#interface fastEthernet 0/1
R2(config-if)#ip nat inside
R2(config-if)#exit
R2(config)#interface fastEthernet 1/0
R2(config-if)#ip nat outside
2）关闭R1（如下图所示）测试外网是否可以正常访问web服务器（因为模拟器有BUG所以需要填加一台Internet主机IP：61.159.62.133测试如下下图所示）
