z IS_IN: The source filtering mode is Include, namely, the report sender requests

the multicast data from only the sources defined in the specified multicast source

list. If the specified multicast source list is empty, this means that the report sender

has left the reported multicast group.

z IS_EX: The source filtering mode is Exclude, namely, the report sender requests

the multicast data from any sources but those defined in the specified multicast

source list.

z TO_IN: The filter mode has changed from Exclude to Include.

z TO_EX: The filter mode has changed from Include to Exclude.

z ALLOW: The Source Address fields in this Group Record contain a list of the

additional sources that the system wishes to hear from, for packets sent to the

specified multicast address. If the change was to an Include source list, these are

the addresses that were added to the list; if the change was to an Exclude source

list, these are the addresses that were deleted from the list.

z BLOCK: indicates that the Source Address fields in this Group Record contain a

list of the sources that the system no longer wishes to hear from, for packets sent

to the specified multicast address. If the change was to an Include source list,

these are the addresses that were deleted from the list; if the change was to an

Exclude source list, these are the addresses that were added to the list.
