一、实验拓扑
二、实验需求
1.所有PC均需要通过DHCP获取IP地址-地址池名称和设备VLAN一致，例如PC1-ip pool vlan10,其中只有业务B网络用户需要访问互联网web服务-需要DNS信息。
2.交换机配置VLAN需要遵循最小VLAN透传原则
3.利用OSPF协议使内外用户互相访问-全网可达（设备Router-ID需要手工配置，和设备编号一致，例如R1-RID：1.1.1.1），
并采用精准宣告的方式进行宣告（例如：172.16.64.1/24接口，宣告：172.16.64.1 0.0.0.0）
4.内网全网可达，并且需要尽可能减小路由表条目数量（汇总采用精确汇总方式），能够利用缺省省去的配置可省略，防止环路，
并且保障安全（在OSPF区域0需要配置认证-采用MD5认证，密码为123456）
5.内网所有用户均可访问互联网（边界路由器配置NAT），ACL采用基础ACL，编号为2000，R3-0/0/2接口不允许宣告在内网中（包含静态）。
6.test设备需要远程登陆到内网telnet-server设备,登录账号为 huawei 密码 123456，登录权限为最高。
7.不允许VLAN 40和VLAN 50 用户访问内网B业务，acl编号为2001，不允许PC1访问PC5，ACL编号为3000。
8.R3-R4中间百兆链路作为备份链路，不允许正常情况下数据通过，需要降低优先级数值配置为100。
9.所有设备严格按照拓扑图标识进行配置，注意大小写。
10.图示中所有服务器和client设备均为体现需求，地址固定，不做更改，在配置时需求注意。clinet1用来模拟内网用户访问互联网（ISP-服务器），
test设备用来测试互联网用户远程登陆内网telent-server主机。
