Question
IGMP SSM Mapping statically binds the multicast source to the multicast group, so that group members of IGMPv1 and IGMPv2 can also access the SSM multicast network. Which of the following descriptions about IGMP SSM Mapping is wrong?
Options
- AIGMP SSM Mapping does not process IGMPv3 report messages. In order to ensure that hosts running any version of IGMP on the same network segment can get SSM services, it is necessary to run IGMPv3 on the multicast router interface connected to the network segment where the member hosts are located.
- BMapping can send join messages of the SSM address on the IGMP querier, and map the group joining information in the IGMPv1 or IGMPv2 member report to the group leaving information.
- CThe multicast source-multicast group of SSM is 224.0.0.0-239.255.255.255.
- DIf the IGMP SSM Mapping function is not enabled, neither IGMPv1 nor IGMPv2 support the deployment of multicast in SSM mode.
