IGMP proxying configuration example
Network requirements
As shown in Figure 17, PIM-DM runs on the core network. Host A and Host C in the stub network receive
VO D i n f o r m a t i o n s e n t t o m u l t i c a s t g r o u p 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.
