If a feature is configured in both IGMP view and interfaceview, the configuration performed in interface view will be given priority.Configuring Basic Functions of IGMPConfiguration PrerequisitesBefore configuring the basic functions of IGMP, complete the following tasks:z Configure any unicast routing protocol so that all devices in the domain are interoperable at thenetwork layer.z Configure PIM-DM or PIM-SMBefore configuring the basic functions of IGMP, prepare the following data:z IGMP versionz Multicast group and multicast source addresses for static group member configuration
