河北科技大學校園網設計和實現

1.背景描述

1.1 部門：信息學院、電氣學院、機械學院……;
信息學院有計算機系、網絡系、電子系；電氣學院有無人機、……系；
1.2 建筑物分布
信息樓、電氣樓、機械樓…、網管中心…
1.3 申請的IPv4地址空間：202.206.64.0—202.206.79.0

設計目標：實現校園網的Intranet，校園網內有Web服務器、Email服務器、FTP服務器等。；校園網的主機可以訪問Internet的Web服務器，外網主機可以訪問科大的Web服務器，名稱是www.hebust.edu.cn，
安全策略
IP地址：DHCP
NAT

2. 設計網絡

2.1 三層網絡的設計思想：接入層、匯聚層、核心層
2.2 接入層 ：VLAN
匯聚層：實現VLAN間主機的路由、跨交換機VLAN內主機的通信
核心層：匯聚層 路由協議：RIPv2、
出口路由器：到外網的默認路由
ISP邊緣路由器：到科技大學的匯總路由
2.3 服務器群：
2.4 IP地址規劃
2.5 路由協議RIPv2、靜態路由

傳播默認路由、匯總路由
