This chapter contains the following sections: • IGMP Commands • IGMP Snooping Commands IGMP Commands Dell Networking OS supports IGMPv1/v2/v3 and is compliant with RFC-3376. Important Points to Remember • IGMPv2 is the default version of IGMP on interfaces. You can configure IGMPv3 on interfaces. It is backward compatible with IGMPv2. • There is no hard limit on the maximum number of groups supported. • IGMPv3 router interoperability with IGMPv2 and IGMPv1 routers on the same subnet is not supported. • An administrative command (ip igmp version) is added to manually set the IGMP version. • All commands previously used for IGMPv2 are compatible with IGMPv3. ip igmp group-join-limit To limit the number of IGMP groups that can be joined in a second, use this feature.
