大型网络实验 小组 7 1、 实验目的  学习大型网络地址规划及线路设计。  全面了解大型网络架构及相关设计规划。  全面学习网络设备的配置。 2、 实验内容 1、 网络拓扑图(图 1) 2、 本次实验中服务器网络使用 172.16.0.0/16 网段,网络互联地址使 用 192.168.0.0/16 网段,用户地址使用 10.0.0.0/8 网段。根据网络 实际需求划分地址空间,要求互联地址第 3 段地址为各组组号,用户 地址第 2 段为组号。例如第 1 组,互联地址为 192.168.1.0/24,用户 地址为 10.1.0.0/16,服务器网段按照要求自行规划。 3、 完成拓扑图中未完成的网络连接,保证服务器接入交换机与核心交 换机之间的可靠连接,服务器主要为内部提供服务。为接入交换机提 供上行链路冗余叠加功能,提高上行带宽。 4、 完成无线路由器的网络连接,为 Laptop2 提供无线网络连接,同时 作为无线网络网关和为 Laptop2 提供 DHCP 服务。 5、 内部网络核心区域使用 OSPF 协议多区域,服务器区域,核心交换区 域,无线服务区域分布在不同区域。 6、 全网 PC 机由 DHCP 服务器提供地址,无线网络由网关设备提供 DHCP 服务。 7、 ISP_Router 与总部区域互联接口地址为 1.1.0.1/32,与分支区域互 联地址为 1.1.0.5/32,ISP 区域设备不允许做任何改动
8、 要求分支区域网络通过隧道技术,直接访问总部内部网络并获取 IP 地址。所有 PC 均可以访问运营商提供的 WWW 服务。 3,实验结果与分析 Ip 部署 总部 设备名称/端口 网段/ip www_Server DNS_Server 172.16.2.1/27 172.16.1.1/27 CE_Router(f0/0)-Core_Switch1(g0/1) 192.168.7.1/30 CE_Router(f0/1)-Core_Switch2(g0/1) 192.168.7.4/30 Server_Switch ( g0/1 ) - Core_Switch1(f0/20) Server_Switch ( -Core_Switch2(f0/20) Core_Switch1(f0/2)-Wlan_Switch(g/1) g0/2 ) Core_Switch1 ( g0/1 ) - Core_Switch2 (g0/2) Core_Switch2(vlan 20) Wlan_Switch(vlan 10) 分支 192.168.7.8/30 192.168.7.12/30 192.168.7.16/30 192.168.7.20/30 10.7.1.254/24 10.7.0.254/24 Branch_Router(f0/0)-Branch_Switch(g0/1) 192.168.7.64/30 Branch_Server 172.16.3.1/27 Branch_Switch(vlan 100) 10.7.32.254/24 Branch_Switch(f0/10) Branch_Switch(g0/2) 10.7.192.2/25 172.16.3.2/27
