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

Configuration procedure
1.
Configure the IP address and subnet mask of each interface as shown in
shown.)
2.
Configure OSPF on the switches to make sure the network-layer is interoperable on the PIM-SM
domain and routing information among the switches can be dynamically updated. (Details not
shown.)
3.
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 Switch D, enable PIM-SM on each interface, and enable IGMPv3
and IGMP SSM mapping on VLAN-interface 400.
[SwitchD] multicast routing-enable
[SwitchD] interface vlan-interface 400
[SwitchD-Vlan-interface400] igmp enable
[SwitchD-Vlan-interface400] igmp version 3
[SwitchD-Vlan-interface400] igmp ssm-mapping enable
