• Source 1, Source 2, and Source 3 send multicast packets to multicast groups in the SSM group
range. It is required to configure the IGMP SSM mapping feature on Device D so that the receiver
host will receive multicast data from Source 1 and Source 3 only.

Configuration procedure
Step1 Configure IP addresses and unicast routing
Configure the IP address and subnet mask of each interface as per Figure 6 . The detailed configuration
steps are omitted here.
Configure OSPF for interoperability among the devices. Ensure the network-layer interoperation in the
PIM-SM domain and dynamic update of routing information among the devices through a unicast routing
protocol. The detailed configuration steps are omitted here.
Step2 Enable IP multicast routing, enable PIM-SM on each interface, and enable IGMP and IGMP SSM
mapping on the host-side interface.
# Enable IP multicast routing on Device D, enable PIM-SM on each interface and enable IGMPv3 and
IGMP SSM mapping on GigabitEthernet 1/1.
