z 

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. 

z 

Host A and Host C are multicast receivers in two stub networks. 

z 

Switch D connects to the network that comprises the multicast source (Source) through 

VLAN-interface 300. 

z 

Switch A connects to stub network N1 through VLAN-interface 100, and to Switch D through 

VLAN-interface 103. 

z 

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. 

z 

IGMP is required on Switch A, Switch B, Switch C, and hosts in N1 and N2. Switch B is the IGMP 

querier on the multi-access subnet.
