摘要
BGP/MPLS VPN技术充分利用了公网的BGP、MPLS等先进技术,通过BGP路由更新报文传递私网路由实现了VPN,通过MPLS解决BGP路由黑洞问题、还为VPNv4路由及BGP更新源分配标签,适合大中型企事业单位异地私网间信息安全可靠快速价廉的传输,成为公网核心技术和研究热点.本文主要研究BGP/MPLS VPN技术中私网路由信息及数据在公网中传输的机制和原理,并通过Dynamips仿真平台实现一个BGP/MPLS VPN网络实例,最后通过抓包及查看LFIB、VPNv4路由表等等表项分析、验证了该机制和原理.
BGP/MPLS VPN technology makes full use of advance technologies of the Internet such as BGP and MPLS.Private routing can be delivered through a BGP update message that implements VPN.The BGP routing black hole problem is solved by MPLS and the distribution label of VPNv4 routing and BGP update source is also available.It is suitable for the transmission of information security and cheap and reliable of private networks in big&mediumsized enterprises.It is the core technology and research hotspot of the Internet.The mechanism and principle of private routing and data transmission through the Internet in BGP/MPLS VPN technology was investigated.A BGP/MPLS VPN network instance by Dynamips simulation platform was implemented.The mechanism and principle of BGP/MPLS VPN were verified and analyzed by the capture packet and LFIB and VPNv4 routing tables.
