SSM Mapping Configuration Example
Network requirements
z
On the PIM-SSM network shown in
Figure 1-6
, the receiver host receives VOD information through
multicast. The receiver host runs IGMPv2, so it cannot specify the expected multicast sources in its
membership reports.
z
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
Figure 1-6
. The detailed
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.
