5. Verify the configuration:
Use the display igmp interface command to view the IGMP configuration and operation status on
each router interface. For example:
# Display IGMP information on GigabitEthernet 2/0/1 of Router B.
[RouterB] display igmp interface gigabitethernet 2/0/1
GigabitEthernet2/0/1(10.110.2.1):
IGMP is enabled
Current IGMP version is 2
Value of query interval for IGMP(in seconds): 60
Value of other querier present interval for IGMP(in seconds): 125
Value of maximum query response time for IGMP(in seconds): 10
Querier for IGMP: 10.110.2.1 (this router)

SSM mapping configuration example
Network requirements
The PIM-SM domain applies both the ASM model and SSM model for multicast delivery. Router D's
GigabitEthernet 2/1/3 serves as the C-BSR and C-RP. The SSM group range is 232.1.1.0/24.
IGMPv3 runs on Router D's GigabitEthernet 2/1/1. 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. You
can configure the IGMP SSM mapping feature on Router D so that the receiver host will receive multicast
data from Source 1 and Source 3 only.
