IGMP proxying configuration example
Network requirements
As shown in Figure 36 , PIM-DM runs on the core network. Host A and Host C in the stub network receive
VOD information destined to multicast group 224.1.1.1.
Configure the IGMP proxying feature on Switch B so that Switch B can maintain group memberships and
forward multicast traffic without running PIM-DM.
