IGMP SSMMapping is bound to multicast through a static multicast source, so that members of IGMPv1 and IGMP2 can also access the SSM multicast network. The following statement about IGMPSSMMapping is wrong? (Radio).

• A.If the IGMP SSM Mapping feature is not enabled, neither IGMPv1 nor IGMPv2 supports multicast for deploying SSM modules
• B.IGMP SSM Mapping does not process reporting messages from IGMPv3 In order to ensure that the same network segment runs any version
• C.IGMP hosts can make SSM services run IGMPv3 on the multicast router socket connected to the network segment where the member host is located
• D.The multicast address of the SSM is 232000~232255255255
