used to verify the forwarding process based on IGMP information in an IGMP enabled Router.

• Packet Handling Group (PHG) - The Conformance test cases in the IGMPv3 PHG group are used to verify the processing of the received IGMPv3 message at the DUT

• Interoperability Group (IOG) - The Conformance test cases in the IGMPv3 IOG Group are used to verify the behavior of a IGPMv3 router in a network support IGMPv2 and IGMPv2 systems.

• Multicast Router Group (MRG) - The Conformance test cases in the IGMPv3 MRG group are used to verify the handling of IGPMv3 reports in an IGMPv3 router and the associated state machine implementations.

• Packet Format Group (PKT) - The Conformance test cases in the IGMPv3 PKT group are used to verify whether IGMP messages generated by an IGMP system are as per the required frame formats.
