Explanation:
Version 3 Reports are sent with an IP destination address of 224.0.0.22, to which all IGMPv3-
capable multicast routers listen. A system that is operating in version 1 or version 2 compatibility
modes sends version 1 or version 2 Reports to the multicast group specified in the Group Address
field of the Report.
There are a number of different types of Group Records that may be included in a Report
message:
A “Current-State Record“ (in response to a Query)
MODE_IS_INCLUDE INCLUDE()
MODE_IS_EXCLUDE EXCLUDE()
A “Filter-Mode-Change Record“ (when the filter mode change)
CHANGE_TO_INCLUDE_MODE TO_IN()
CHANGE_TO_EXCLUDE_MODE TO_EX()
A “Source-List-Change Record“ (when the source list change)
ALLOW_NEW_SOURCES ALLOW()
