Command Usage

To fully enable PIM-DM, you need to enable multicast routing globally for the router with the ip multicast-routingcommand (page 4-288),enable PIM-DM globally for the router with the router pim command (page 4-302),and also enable PIM-DM for each interface that will participate in multicast routing with the ip pim dense-modecommand.

If you enable PIM on an interface, you should also enable IGMP on that interface.

Dense-mode interfaces are subject to multicast flooding by default, and are only removed from the multicast routing table when the router determines that there are no group members or downstream routers, or when a prune message is received from a downstream router.
