Network requirements
■ Receivers receive VOD information through multicast. The receiver groups of 
different organizations form stub networks, and one or more receiver hosts 
exist in each stub network. The entire PIM domain operates in the dense mode.
■ Host A and Host C are multicast receivers in two stub networks.
■ Switch D connects to the network that comprises the multicast source (Source) 
through VLAN-interface 300.
■ Switch A connects to stub network N1 through VLAN-interface 100, and to 
Switch D through VLAN-interface 103.
■ Switch B and Switch C connect to stub network N2 through their respective 
VLAN-interface 200, and to Switch D through VLAN-interface 101 and 
VLAN-interface 102 respectively.
■ IGMPv2 is to run between Switch A and N1, and between Switch B/Switch C 
and N2.
