Which statement about IGMPv3 is true?
- It sends IGMP query messages with a TTL value of 1 addressed to the all-host group (224.0.0.1).
- It does not accept a leave group message from the hosts that have already joined the multicast group.
- It rejects any group-specific query message that is sent from the hosts that want to join a multicast group.
- It enables a multicast receiver to signal to the first hop router the multicast sources from which it expects to receive traffic.
| Answers Explanation & Hints:
IGMPv3 is an extension of IGMPv2 with added support for multicast source filtering done through the use of a new message type called Version 3 membership report. It supports applications that explicitly signal sources that want to receive multicast traffic by using the membership report in the Include or Exclude mode. |
