SSM Mapping Configuration Example
Network requirements
z The PIM-SM domain applies both the ASM model and SSM model for multicast delivery.
Switch D’s VLAN-interface 104 serves as the C-BSR and C-RP. The SSM group range is
232.1.1.0/24.
z IGMPv3 runs on Switch D’s VLAN-interface 400. The receiver host runs IGMPv2, and does
not support IGMPv3. Therefore, the Receiver host cannot specify expected multicast
sources in its membership reports.
z 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 Switch D so that
the receiver host will receive multicast data from Source 1 and Source 3 only.
