SSM Mapping Configuration Example

Network requirements
On the PIM-SSM network shown in
multicast. The receiver host runs IGMPv2, so it cannot specify the expected multicast sources in its
membership reports.
It is required to 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 IP addresses and unicast routing
Configure the IP address and subnet mask of each interface as per
configuration steps are omitted here.
Configure OSPF for interoperability among the switches. Ensure the network-layer interoperation on
the PIM-SSM network and dynamic update of routing information among the switches through a unicast
routing protocol. The detailed configuration steps are omitted here.
2) 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.
