1、实验拓扑图
2、实验目的
Spoke-CE1 与 Spoke-CE2 为同一家公司分属于两地的分支边 界网络设备，Hub-CE 为该公司总部的边界网络设备，分支设备 与其所连接的 PE 设备间运行 OSPF 协议，总部设备与其所连接 的 PE 设备间运行 EBGP；Spoke-PE1、Spoke-PE2、RTA、HubPE 为运营商网络，内部 IGP 使用 OSPF 连通，外网构建 BGP 网 络，令 Spoke-PE1、Spoke-PE2 与 Hub-PE 之间实现 MPLS VPN，在穿越 BGP 网络环境下实现公司内部的通信；同时要求 分支网络须通过总部网络学习其它分支的路由条目，各分支彼此 间不允许直接学习与通信
