Figure 6-20. Isolating IP Multicast Traffic in a Network

■In the above figure, the multicast group traffic does not go to switch 1 and beyond because either the port on switch 3 that connects to switch 1 has been configured as blocked or there are no hosts off of switch 1 or switch 2 that belong to the multicast group.

■For PC #1 to become a member of the same multicast group without flooding IP multicast traffic on all ports of switches 1 and 2, IGMP must be configured on both switches 1 and 2.
