It was the first IGMP version that allowed to explicitly announce its willingness to receive particular multicast traffic. This version had two messages only: The Membership Query was always sent to 224.0.0.1 by multicastrouters,and the Membership Report was always sent by stations to the group that a station wanted to join. There was no message to...

The general Membership Query is used to find out all multicast groups that the stations are subscribed to. The group-specific Membership Query is u...

Apr 16, 2021 · To enable SSM, you require to configure IGMPv3 on all your network where multicast traffic need to flow. Since I had a opportunity to take packet captures during SSM testing, I thought to write a post about IGMPv3 using those captures. IGMP version 3 defines in RFC3376 (2002) and most of the details of this post directly come from that RFC.
