基于MPLS与BGP的VPN构建与应用研究

针对GRE、IPSEC构建的虚拟私有网络存在数据隔离、互访控制难于实现等问题。文章分析了产生这些问题的根源,提出采用MPLS和BGP技术构建虚拟私有网络的设计思想,并通过仿真平台加以验证。实践证明,采用这种方法在解决路由冲突、数据隔离、站点间访问控制等方面要优于传统的VPN技术。

VPN construction and application research based on MPLS and BGP

There are data isolation and difficulty in realizing exchange visit control in terms of virtual private network of GRE, IPSEC construction.This paper analyzes the origins of these problems, puts forward the design of the MPLS and BGP technology to construct virtual private network, and applies the technology through the simulation platform. It proves that using this method is superior to the traditional VPN technology in solving routing conflict, data isolation, inter-site access control and other aspects.
