写了不少文章讲解不同厂商设备的配置,很多小伙伴希望我给讲讲如何构建一个大型企业网,这里我借一个实例讲讲中大型企业网络如何搭建 。所有实验配置我全部无偿奉献给各位小伙伴,该网络涉及到防火墙的配置、无线网络组网、VRRP、mstp、OSPF及认证、BGP、DHCP中继、nat技术、路由选路,欢迎有兴趣的小伙伴收藏加关注 。
需求如下:
1.做必要隔离,且放环;
2.终端接口接入网络后无延迟转发;
3.汇聚后交换机之间要增加带宽;
4.网关配置在汇聚层上,要保证网关冗余;
5.内部使用可靠的IGP进行路由学习和发布,并保证设备身份的合法性;
6.通过BGP协议跟总部进行路由学习,实现互访,要求缺省互访流量都经过AR1访问总部,当AR1出现故障能自动切换至AR2;
7.要求园区网内所有PC终端都通过公司统一的DHCP服务器完成地址分发;
8.使用AC+瘦AP进行无线网络组网;
9.出口防火墙需要做必要的安全策略,只能内网主动发起访问外网;
10.出口防火墙要配置必要的NAT技术使得内网能够访问ISP或者互联网 。
