这个项目主要实现思路关键点之独孤九剑：
Ip地址的规范
接口对应表的整理
主次关系的整理
分清楚什么是二层技术什么是三层技术
对于相同的预配置先在记事本写好，利用crt直接粘贴复制，这样节省时间和提高效率。
几种交换协议的一句话理解：
Vtp 是用来简化vlan 的配置，思科专有。公有GVRP.
Vtp 配置方法：两台交换机之间用trunk 相连，配置服务端与客户端，配置相同的密码，
域名，版本。服务器配置版本高于客户机。
Stp pvst mst 生成树，快速生成树，多生成树。
生成树是用来防止二层环路，三层环路用路由协议来防环。原理是通过阻塞一条链路来防环。
Pvst 工程中主要用来对不同vlan 做冗余备份。
Mst 是pvst 的升级版，通过不同实例给vlan 做冗余备分。
HSRR VRRP GLBP 是用来给网关提供冗余备份。
通过使作几个不同的组达到给不同vlan 提供冗余备份作用。
Ospf rip eigrp 将不同的vlan 的子网消息宣告出去。
如果trunk 有两线，一定要放到二层组中。
具体代码如下：
1）路由交换预配置

查看日志信息可能会有问题
conf t
host r1
clock timezone GTM 8 \\设置时区
line c 0 \\进入控制台
logg sy \\日志同步,以免日志把正常输入打乱
no ip domain-lookup \\关掉域名解析功能,不然打错命令会等待30秒
enable password [email protected] \\明文密码
enable secret [email protected] \\密文密码更安全，同时明文密码无效
username luliechu privilege 3 secret [email protected] \\本地用户名和密码并且赋予权限
line vty 0 4 \\开启远程终端

8）在出口路由器和分公司路由器上走ppp协议实现全网互通
R1配置
En
Conf t
Username r2 password cisco
Int s0/0/0
Encapsulation ppp
Ppp authentication chap
end
write
R2配置
En
Conf t
Username r1 password cisco
Int s0/0/0
Encapsulation ppp
Ppp authentication chap
End
Conf t
interface Loopback0
ip address 4.4.4.4 255.255.255.255
No shut
interface Serial0/0/0
Clock rate 64000
ip address 113.105.134.86 255.255.255.0
No shut
interface FastEthernet0/0
ip address 218.23.88.1 255.255.255.0

9）将公司内部接入层交换机端口加入到对应的vlan，把电脑连接上交换机，整个项目完成！
实例：将iou3当做人事办公室，配置如下
Iou3上
En
Conf t
Int rang f0/3-24
Sw mo acc
Sw acc vlan 10
End
Write
10）发布web服务器出去让外网用户能够访问到公司利用web服务器发布的消息
在出口路由器上配置
En
Conf t
Ip nat inside source static tcp 192.168.2.5 80 113.105.134.85 80
Access-list 1 permit 192.168.2.0 0.0.0.255
End
Write
验证结果如下：
11）配置acl8.0网段的用户只能访问公司ftp服务器，各vlan部分之间不能互访,但是网管1点段可以访问任意内外网方便管理，公司ftp是可以让任何人都访问到使用，web服务器除了8.0的用户其他用户都可以访问得到，公司除了8.0网段的用户，其他用户都可以访问web服务器和ftp服务器以及外网，只是不能访问到其他内部部门网段而已。
备注：真实环境和iou都是两边路由器配置一模一样，在pt中因为没有做hsrp，所以在
调用acl时候，sw1分别只调用int vlan30 -40 而在sw2上只调用50-80

Int vlan 20到80之间分别调用acl命令如下;因为这里需要vlan10和所有人通讯，服务器是管理员在管理，并且所有人都可以访问它，所以并没有写入acl，实际上也是这样，当然你可以精确到哪个ip地址，写法完全一样
ip access-group 101 in
ip access-group 102 in
ip access-group 103 in
ip access-group 104 in
