IGMP Proxying Configuration Example
Network requirements
• PIM-DM is required to run on the core network. Host A and Host C in the stub network receive VoD
information sent to multicast group 224.1.1.1.
• It is required to configure the IGMP proxying feature on Device B so that Device B can maintain
group memberships and forward multicast traffic without running PIM-DM.

Configuration procedure
Step1 Configure IP addresses
Configure the IP address and subnet mask of each interface as per Figure 7 . The detailed configuration
steps are omitted here.
Step2 Enable IP multicast routing, PIM-DM, IGMP, and IGMP proxying.
# Enable IP multicast routing on Device A, PIM-DM on GigabitEthernet 2/1, and IGMP on
GigabitEthernet 1/1.
