4-19PIM Configuration ExamplesPIM-DM Configuration ExampleNetwork requirementsz Receivers receive VOD information through multicast. The receiver groups of differentorganizations form stub networks, and one or more receiver hosts exist in each stub network. Theentire 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) throughVLAN-interface 300.z Switch A connects to stub network N1 through VLAN-interface 100, and to Switch D throughVLAN-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 IGMPquerier on the multi-access subnet.Network diagramFigure 4-7 Network diagram for PIM-DM configurationEthernetEthernetEthernet N1N2Vlan-int102Vlan-int102Vlan-int103Vlan-int103Device Interface IP address Device Interface IP addressSwitch A Vlan-int100 10.110.1.1/24 Switch D Vlan-int300 10.110.5.1/24Vlan-int103 192.168.1.1/24 Vlan-int103 192.168.1.2/24Switch B Vlan-int200 10.110.2.1/24 Vlan-int101 192.168.2.2/24Vlan-int101 192.168.2.1/24 Vlan-int102 192.168.3.2/24Switch C Vlan-int200 10.110.2.2/24Vlan-int102 192.168.3.1/24Configuration procedure1) Configure the interface IP addresses and unicast routing protocol for each switch
