示例：使用单宿主 EVPN 配置 PBB
此示例说明如何将提供商主干桥接 （PBB） 与以太网 VPN （EVPN） 集成。通过这种集成，核心中的控制平面操作得以简化，提供比常规 EVPN 更快的融合和可扩展性增强。PBB-EVPN 应用包括数据中心互连 （DCI） 和运营商以太网 E-LAN 服务。
要求
此示例使用以下硬件和软件组件：
三台提供商边缘 （PE） 设备，每台设备连接到单宿主客户站点。
单个宿主到 PE 设备的四个客户边缘 （CE） 设备。
在所有 PE 路由器上运行的 Junos OS 17.2R1 或更高版本。
准备工作：
配置设备接口。
在所有 PE 设备上配置 IGP，例如 OSPF。
在 PE 设备之间建立内部 BGP 会话。
在 PE 设备上启用 RSVP。
在 PE 设备之间配置 MPLS 和标签交换路径 （LSP）。
概述和拓扑
从 Junos OS 17.2R1 版开始，PBB 与以太网 VPN （EVPN） 集成，可显著减少跨核心的控制平面学习，从而允许大量第 2 层服务（如数据中心连接）以简化的方式传输网络。
在 PBB-EVPN 网络中，PBB 核心中的骨干核心网桥 （BCB） 设备将替换为 MPLS，同时保留 PBB 主干边缘网桥 （BEB） 的服务扩展属性。B 组件（提供商路由实例）使用 EVPN BGP 信令发出信号，并使用提供商边缘 （PE） 和提供商 （P） 设备封装在 MPLS 中。因此，PBB-EVPN 将 PBB 的巨大扩展特性与传统基本 MPLS 核心网络的简单性相结合，与常规 PBB 相比，可显著减少全网状态信息量。
