IGMP proxying configuration example
Network requirements
As shown in Figure 29:
•
PIM-DM runs on the core network.
•
Host A and Host C on the stub network receive VOD information sent to multicast group
224.1.1.1.
Configure the IGMP proxying feature on Router B so that Router B can maintain group memberships
and forward multicast traffic without running PIM-DM.
