使用华为eNSP组网试验⑹-组建基于BGP的网络
BGP(Border Gateway Protocol -- 边界网关协议)是一种在自治系统之间动态交换路由信息、具有丰富的路由控制机制、稳定而安全的路由协议路由协议，一般部署在骨干(主要、核心)路由器。
BGP适用于大中型网络的组建，在很多企业当中都有应用。
一般情况下，企业的网络当中不会只是简单地使用一种网络协议，都会混杂着启用很多的网络协议并且根据需求进行逻辑隔离，也可以在一种协议当中引用另外一种协议的部分网络资源。
比如，企业当中有办公网络、物联网、视频监控网络等，在这样的情况下为了节约网络硬件，办公、自动化、视频都在同一个网络设备上但进行了分割，办公网使用OSPF、自动化和视频使用BGP，三个网络分开互不影响，根据需要可以设定路由来完成特殊的应用。
BGP组网略微复杂一点，根据组建需求配置参数略微多，BGP需要学习的内容很多。
一、常用查询的命令
①display bgp routing-table
②refresh bgp all export
③display ip interface brief
④display bgp peer
⑤display ip routing-table protocol bgp
