PIM-DM configuration example

Network requirements

As shown in Figure 33, VOD streams are sent to receiver hosts in 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 N1 and N2.

IGMPv2 runs between Router A and N1 and between Router B, Router C, and N2.

Configuration procedure

1. Configure the IP address and subnet mask for each interface as per Figure 33. (Details not shown.)

2. Configure OSPF on the routers in the PIM-DM domain to make sure network-layer is interoperable

among the routers and routing information among the routers can be dynamically updated.

(Details not shown.)

3. Enable IP multicast routing, IGMP, and PIM-DM :
