Membership Report

Membership Report
IGMPv3 receivers signal their membership to a multicast host group in one of two possible
modes: Include and Exclude.
Include When operating in Include mode, the receiver announces its membership to a host
group and provides a list of IP addresses (referred to as the include list) from which it wants to
receive traffic.
Exclude When operating in Exclude mode, the receiver announces membership to a host
group and provides a list of IP addresses (referred to as the exclude list) from which it does not
want to receive traffic. Obviously, this indicates that the host will only receive traffic from other
sources whose IP addresses are not listed in the exclude list.
To receive traffic from all sources, a host transmits an empty exclude list.
