华为项目实验

实验目的 

增强分析和配置中小型企业网络的综合能力

实验内容

本实验模拟了一个企业网络场景， 其中R1和R2为公司总部路由器，交换机S1、S2、S3组成了总部的园区网，R3、R4、 R5为公司分部的路由器。 总部园区网中3台交换机都运行MSTP协议，用来防止二层冗余网络中的环路以及实现 不同VLAN间流量的负载分担，同时还配置了MSTP保护功能以提高网络的可靠性和安全性。 R1、R2、S2、S3运行IS-IS路协议，以实现总部网络的互通。S2和S3使用IS-IS 下发的缺省路由访问总部之外的网络。另外，为了提高网络的安全性，还需要配置IS-IS 认证功能。 R3、R4、R5运行OSPF路由协议，以实现公司分部网络的互通。总部与分部之间 通过BGP路由协议互通，同时需要通过修改BGP路由的属性来实现流量的负载分担。
