Figure 40   Network diagram for PIM-DM configuration

■

Receivers receive multicast VOD information through multicast. The receiver 
groups of different organizations form two stub networks, and at least one 
receiver host exists in each stub network. The entire PIM domain operates in 
the dense mode.

■

Host A and Host C are multicast receivers in the 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 needs to run between Switch A and N1, and also between Switch B, 
Switch C, and N2. Typically Switch B acts as the querier.
