基于OPNET的BGP4重分布的仿真

Redistribution Between BGP4 and IGP Based on OPNET

边界网关协议BGP4是用于自治系统之间交换路由信息的动态分布式路由协议。作为BGP4路由策略之一的路由重分布是自治系统之间信息交互时控制流量的重要环节。文中首先简单介绍了BGP4路由协议及相关内容,然后以BGP4路由重分布为主要讨论对象,利用OPNET仿真软件建立网络仿真模型,通过具体实例详细探讨了BGP4路由重分布在网络设计过程中存在的问题及相应的解决方法,深入理解BGP4路由重分布的机理,从而为网络规划设计更好地提供客观、可靠的定量依据。

Border Gateway Protocol BGP4 is a distributed routing protocol used by AS to interchange routing information. Redistribution is an important node for the information exchanging between networks to control traffic. First, this article briefly introduces the definition of BGP4 , and then taking an example of simulation of redistribution between BGP4 and IGP, discussing by the results of simulation, we can offer an reference for network engineers as perfecting network architectures.
