3)  Verify the configuration  

Carry out the display igmp interface command to view the IGMP configuration and operation status on 

each switch interface. For example:  

# Display IGMP information on VLAN-interface 200 of Switch B.  

[SwitchB] display igmp interface vlan-interface 200 

 Vlan-interface200(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) 

  Total 1 IGMP Group reported 

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.
