课程名称：Cisco BGP配置与实验 - 从基础到高级！ 课程概述：边界网关协议（BGP）配置一直是一项复杂的任务。此课程旨在使学习者轻松理解BGP的概念，包含许多实验，帮助学生在实际中熟练操作BGP。BGP被视为一种“路径向量”路由协议，是用于在不同自主系统之间交换路由信息的外部网关协议（EGP）。它是互联网运行的唯一协议，具有强大的可扩展性和稳健性。一旦BGP对等体建立了邻接关系，它们就会共享完整的路由表，之后，仅会将路由表的变更转发给对等体。 BGP指标包括多个属性，且有三张表：邻接表、BGP表和路由表。eBGP的管理距离（AD）为20，iBGP为200，BGP使用TCP-179端口进行通信。它以增量和触发更新的方式工作（iBGP的更新间隔为5秒，eBGP的更新间隔为30秒），使用AS号跟踪不同的管理域，其中1-64511为公共AS号，64512-65535为私有AS号。 本课程通过多种实验，从简单的BGP配置到复杂的路由反射器和联合体，全面提高学生在实施BGP协议方面的专业能力。课程内容涵盖BGP的主要属性，如权重、本地优先级、AS路径、多出口分配码（MED）和社区。此外，还讲解了如何读取BGP表、疑难解答BGP邻接关系和网络广告等重要主题。 学习主题包括： 1. 简单BGP配置 2. 与非连接邻居的BGP配置 3. iBGP与eBGP 4. 如何读取BGP表 5. 在BGP中广告子网 6. BGP中的自动汇总 7. BGP邻接状态 8. BGP消息 9. BGP邻接关系故障排除 10. BGP网络广告故障排除 11. 权重属性 12. 本地优先级 13. AS路径预先添加 14. 起源代码 15. 多出口分配码（MED） 16.

BGP Configuration is always a big task to do. This Course has made it very easy for students to understand the BGP Concepts. It has many labs which will eventually make you comfortable working with BGP.Border Gateway Protocol (BGP) is considered a "Path Vector" routing protocol. It is an exterior gateway protocol (EGP) that is used to exchange routing information among routers in different autonomous systems. It is the only protocol which enables Internet to function. So it is very robust and scalable routing Protocol. Once BGP peers form a neighbor relationship, they share their full routing table. Afterwards, only changes to the routing table are forwarded to peers.BGP metric is BGP attributes. It has 3 tables, neighbor table, BGP table and Routing table. The AD (Administrative Distance) for eBGP routes is 20, iBGP is 200. It uses TCP-179. It's Peers use incremental and triggered updates(5 sec interval for IBGP and 30 sec interval for EBGP). It uses AS numbers to keep track of different administrative domains. 1-64511 are public, 64512-65535 are private autonomous numbers.This course has many Labs which will make you very strong and comfortable in Implementing this protocol in your organization or at your home lab. You will get expertise on Attributes of BGP such as Weight, Local Preference, AS Path, MED , ORGIN and Communities. Since It runs the Internet, so we need a protocol which gives flexibility, that is why BGP is used. Only drawback is that It is extremely slow to converge.Many more things like Route Reflectors, Confederation are also covered so that you get complete information about this BGP.Here is the list of topics covered in it1.
