PIM configuration examples
PIM-DM configuration example
Network requirements
As shown in Figure 46, 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 is operating in the dense mode.
Host A and Host C are multicast receivers in two stub networks.
IGMPv2 runs between Switch A and N1 and between Switch B/Switch C and N2.

Configuration procedure
1. Configure the IP address and subnet mask for each interface as per Figure 46. (Details not shown.)
2. Configure OSPF on the switches in the PIM-DM domain to make sure they are interoperable at the
network layer. (Details not shown.)
3. Enable IP multicast routing, IGMP and PIM-DM:
