摘要
BGP/MPLS VPN具有良好的可扩展性和灵活性,是目前发展最为迅速的VPN技术之一。首先分析了BGP/MPLS技术的VPN模型,对BGP/MPLS VPN的基本原理进行介绍,然后在基于ATM框架下最大限度地兼顾原有控制平面,在上层控制平面少量修改的情况下,有效地利用内部虚拟MAC地址信息将控制平面和转发平面有机联系起来,在不支持MPLS标签交换的交换芯片上实现VPN报文转发,并提出了一套完整的设计和实现方案。
BGP/MPLS VPN, with good scalability and flexibility, is one of the rapidly growing VPN tech- nologies. VPN model with BGP/MPLS technology is analyzed and the basic principle of BGP/MPLS VPN presented in this paper. Cunsideration is given to the original control surface based on ATM architecture, and with certain modification of upper control surface, the control surface and forwarding plane is organically related through internal virtual MAC address, and VPN packets transmitting is implemented on the switch chip with no support to MPLS label switching. This paper finally proposes a complete set of design and implementation scheme.
