PIM Configuration Examples

PIM-DM Configuration Example

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.
