3 IGMP基本功能配置举例
3.1 组网需求
如 图 1 所示，网络中运行OSPF和PIM，接收者通过组播方式接收视频点播信息，不同组织的接收 者组成末梢网络N1 和N2，Host A和Host C分别为N1 和N2 中的组播信息接收者。Switch A与N1 之 间运行IGMPv2，Switch A为IGMP查询器；Switch B、Switch C与N2 之间也分别运行IGMPv2，且 由于Switch B的接口IP地址较小，因此由其充当IGMP查询器。现要求： • 对网络 N1 内的接收者所能加入的组播组没有限制； • 控制网络 N2 内的接收者只能加入组播组 224.1.1.1。 图1 IGMP 基本功能配置组网图

1 简介
IGMP（Internet Group Management Protocol，互联网组管理协议）用于在三层设备和其直连网段 中的用户主机之间建立和维护组播组成员关系。本文介绍了 IGMP 的典型配置举例。
2 配置前提
本文档中的配置均是在实验室环境下进行的配置和验证，配置前设备的所有参数均采用出厂时的缺 省配置。如果您已经对设备进行了配置，为了保证配置效果，请确认现有配置和以下举例中的配置 不冲突。 本文档假设您已了解 IGMP 特性。

3.3 使用版本
本举例是在 S5820V2_5830V2-CMW710-R2418P01 版本上进行配置和验证的。
3.4 配置注意事项
由于不同版本 IGMP 协议的报文结构与种类不同，因此需要为同一网段上的所有三层交换机配置相 同版本的 IGMP，否则 IGMP 将不能正常运行。
3.5 配置步骤
(1) 配置 PIM-DM 域内各交换机的 IP 地址和单播路由协议 # 配置 PIM-DM 域内交换机上各接口的 IP 地址和子网掩码，具体配置过程略。 # 配置 PIM-DM 域内的各交换机之间采用 OSPF 协议进行互连，确保 PIM-DM 域内部在网络层互通， 具体配置过程略。 (2) 配置 Switch A # 在 Switch A 上使能 IP 组播路由，在接口 Vlan-interface101 上使能 PIM-DM，并在主机侧接口 Vlan-interface 100 上使能 IGMP。

3.2 配置思路
• 因共享网段 N2 内有多台 IGMP 交换机，为实现本组网需求，需要在该共享网段内的所有 IGMP 交换机上都配置相同的 IGMP 组播组过滤器。
• 为实现 IGMP 组播组过滤器控制主机加入组播组的范围，需要为其创建基本 ACL，并在该 ACL 规则中指定允许主机加入的组播组范围。
