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

Configuration procedure
1) Configure IP addresses
Configure the IP address and subnet mask of each interface as per Figure 5-7 . The detailed
configuration steps are omitted here.
2) Enable IP multicast routing, PIM-DM, IGMP, and IGMP Proxying.
# Enable IP multicast routing on Switch A, PIM-DM on VLAN-interface 101, and IGMP on
VLAN-interface 100.
