IGMP proxying configuration example
Network requirements
PIM-DM runs on the core network. Host A and Host C in the stub network receive VOD information sent
t o m u l t i c a s t g ro 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.

Configuration procedure
1. Assign an IP address and subnet mask to each interface according to Figure 31. (Details not
shown.)
2. Enable IP multicast routing, PIM-DM, IGMP, and IGMP proxying:
# Enable IP multicast routing on Router A, PIM-DM on Serial 3/1/1, and IGMP on GigabitEthernet
2/1/1.
