摘要
介绍了实现基于BGP协议实现的MPLS VPN所需要的各个组成构件及其在构建VPN的过程中所起的作用,介绍了BGP/MPLS VPN的工作原理,并举出实例,对一个具体的VPN数据报在某个具体的MPLS骨干网络中传递的整个过程、及其在每个传递环节中的处理等做出了具体的描述,由此达到对BGP/MPLS VPN的整个工作过程进行剖析描述的目的,并详细而清晰地说明了其工作机制。在此基础上,结合MPLS网络所特有的一些特性,进一步分析和阐述了在MPLS网络上实现VPN所带来的种种优越性。
Firstly, all the components and its effects ofBGP/MPLS VPN are described. Secondly, the principle ofBGP/MPLS VPN is introduced. An example of a real VPN datagram being passed through a real MPLS net is stated in details for deep sight in the whole work prcess and work mechanism. With some advantages of MPLS net, based on above all, the advantages of this technology are presented and understood easily.
