摘　　要：IGMP Snooping是一种运行在数据链路层的组播管控机制。文中简要介绍了IGMP Snooping基本的工作机制,描述了IGMP Snooping在一个VPLS域中的工作原理,详细阐述了IGMP Snooping报文提取、创建组播组、组播成员增删等要点的实现原理,并通过在一个VPLS模拟场景中运行IGMP Snooping的方式对该实现方式进行验证。实验结果表明,该设计方案可以在VPLS网络中实现IGMP Snooping功能。IGMP Snooping is a multicast control mechanism that runs on the data link layer. This paper briefly introduces the basic working mechanism of IGMP Snooping,describes the working principle of IGMP Snooping in a VPLS domain,and elaborates the implementation principle of IGMP Snooping message extraction,creating multicast group and multicast member addition and deletion. This method is verified by running IGMP Snooping in a VPLS simulation scenario. The experimental results show that the scheme can implement IGMP Snooping in VPLS network.
