Prerequisites for IP Multicast Routing

You must enable basic IP multicast routing and configure the PIM version and the PIM mode. Then the
software can forward multicast packets, and the switch can populate its multicast routing table.
You can configure an interface to be in PIM dense mode, sparse mode, or sparse-dense mode. The switch
populates its multicast routing table and forwards multicast packets it receives from its directly connected
LANs according to the mode setting. You must enable PIM in one of these modes for an interface to perform
IP multicast routing. Enabling PIM on an interface also enables IGMP operation on that interface.
