【摘要】 BGP是一种路径矢量路由协议,作为目前唯一的EGP协议,能够支持10万+级的路由条目数,通过丰富的路径属性参与选路实现路由策略,技术复杂并广泛应用在互联网的核心骨干网。在对BGP协议基本术语、消息类型及选路原则等工作原理等深入研究的基础上,设计了一种多AS多出口及有路由选路需求的BGP实验网络模型,并通过EVE-NG仿真平台实现。结合扩展ping及对BGP转发等表分析,仿真结果验证了BGP协议机制和原理,为在实际网络中的部署提供了重要参考,并且该实例可直接迁移到实际网络中。更多还原

【Abstract】 BGP is a path vector routing protocol. As the only EGP protocol at present,it can support 100 thousand +level routing number and participate in routing strategy through rich path attributes. The technology is complex and widely used in the core backbone of the Internet. Based on the in-depth study of the basic terms,message types and route selection principles of BGP protocol,a BGP experimental network model with multiple AS multiple exits and routing requirements is designed and implemented through the EVE-NG simulation platform. Combining the extended Ping and the BGP forwarding table analysis,the simulation results verify the mechanism and principle of the BGP protocol,which provides important reference for the deployment of the actual network,and the instance can be directly migrated to the actual network.更多还原
