Does IGMPv3 support IGMPv1 General Query, IGMPv2 Group-Specific Query, and IGMPv3 Source/Group-Specific Query?

IGMPv3, or Internet Group Management Protocol version 3, is designed to support more complex multicast management functionalities compared to its predecessors, IGMPv1 and IGMPv2. One of the primary enhancements in IGMPv3 is its ability to support source-specific multicast (SSM).

In relation to the question, IGMPv3 indeed supports the general query message format found in IGMPv1 and the group-specific query message format from IGMPv2. This backward compatibility allows IGMPv3 devices to communicate effectively with multicast groups where some members may still be using IGMPv1 or IGMPv2.

Additionally, IGMPv3 introduces the source/group-specific query, enhancing the capability to manage multicast memberships by explicitly specifying which sources a host wishes to receive traffic from. This support for queries from previous versions along with the new source-specific queries underscores IGMPv3's flexibility and comprehensiveness in managing multicast traffic.

Thus, it is accurate to state that IGMPv3 supports IGMPv1 General Query, IGMPv2 Group-Specific Query, and its own IGMPv3 Source/Group-Specific Query, affirming the truth of the statement.
