MPLS/BGP-VPN技术应用

Application of MPLS/ BGP-VPN Technology

围绕现有网络中的虚拟私有网络(VPN)应用技术,首先介绍基于MPLS/BGP的VPN技术,包括MPLS/BGP VPN技术的原理和涉及的主要概念,MPLS VPN的网络结构以及MPLS/BGP VPN中的R D和R T等概念。通过详细描述路由发布和数据转发过程,深入分析MPLS/BGP VPN技术的通信原理,在理论基础上,使用阿尔卡特的成熟网络设备进行实例配置,给出具体的配置思路和步骤,使MPLS/BGP VPN技术的原理和实际应用进行了有效地结合,为其他网络设备配置提供参考。

Centering on the Virtual Private Network （VPN） application technology in existing network, this paper firstly introduces the VPN technology based on MPLS/BGP, including the principles and main concepts of MPLS/BGP VPN technology, the MPLS VPN network architecture and the concepts of RD and RT in MPLS/BGP VPN. Based on detailed description of routing distribution and data forwarding process, this paper deeply analyzes the communication principles of MPLS/BGP VPN technology. Finally, on the basis of theory, it uses the Alcatel’s mature network device to implement the instance configuration, and gives the specific configuration ideas and approaches to effectively combine the technical principle and actual application of MPLS/BGP VPN technology, and provides some references for other network device configuration.
