4.2.16 " If the set of Group Records required in a Report does not fit within the size limit of a single Report message (as determined by the MTU of the network on which it will be sent), the Group Records are sent in as many Report messages as needed to report the entire set.

If a single Group Record contains so many source addresses that it does not fit within the size limit of a single Report message, if its Type is not MODE_IS_EXCLUDE or CHANGE_TO_EXCLUDE_MODE, it is split into multiple Group Records, each containing a different subset of the source addresses and each sent in a separate Report message. If its Type is MODE_IS_EXCLUDE or CHANGE_TO_EXCLUDE_MODE, a single Group Record is sent, containing as many source addresses as can fit, and the remaining source addresses are not reported; though the choice of which sources to report is arbitrary, it is preferable to report the same set of sources in each subsequent report, rather than reporting different sources each time."
