•
VOD streams are sent to receiver hosts in multicast. The receiver groups of different
organizations form stub networks, and one or more receiver hosts exist on each stub network.
•
The entire PIM domain operates in the dense mode.
•
Host A and Host C are multicast receivers on two stub networks.
•
IGMPv2 runs between Switch A and N1, and between Switch B, Switch C, and N2.
