摘　　要：分析了基于BGP+EVPN+vpnv4方案,实现云平台跨资源池异地容灾的前提条件。阐述了为实现云平台业务异地容灾的目标,如何设计跨机房云平台网络拓扑和跨域VPN技术方案选择等。给出了EVPN、L2VPN等业务接入通用配置模板,对如何配置BGP路由策略和业务迁移前配置分布式网关给出了指导建议。最后对云平台虚拟机跨资源池迁移进行对比分析,为迁移问题的排查和业务系统的异地容灾提供指导,同时为今后进一步优化提供方向。This paper analyzes the remote disaster recovery across resource pools based on the BGP+EVPN+vpnv4 technology. In order to achieve the goal of remote disaster recovery of cloud service, it describes how to design the topology and the scheme selection of VPN technology crossing multiple domains. It gives the general configuration templates for EVPN and L2 VPN, and gives guidance suggestions on how to configure BGP routing policies and configure distributed gateway before migration of running services.Finally, it makes a comparative analysis of remote migration of virtual machines across resource pools based on cloud platform,which provides guidance for the investigation of migration problems and remote disaster recovery of business systems.
