IGMP SSM mapping configuration example
Network requirements
As shown in Figure 27:
• The PIM-SM domain uses both the ASM model and SSM model for multicast delivery.
GigabitEthernet 2/1/3 on Router D serves as the C-BSR and C-RP. The SSM group range is
232.1.1.0/24.
• IGMPv3 runs on GigabitEthernet 2/1/1 on Router D. The receiver host runs IGMPv2, and does not
support IGMPv3. Therefore, the receiver host cannot specify expected multicast sources in its
membership reports.
• Source 1, Source 2, and Source 3 send multicast packets to multicast groups in the SSM group
range.
Configure the IGMP SSM mapping feature on Router D so that the receiver host can receive multicast
data from Source 1 and Source 3 only.
