Stopping snoopers from snooping non-IGMP messages > Controlling which addresses create All Groups entries
Looking at the above outputs, note that debugging did not print out any messages about the
OSPF router after we removed the address, but it did tell us when the port had been
removed from the All Groups list. Also, remember that port 24 only times out of the All
Groups list when its internal IGMP message timer counts down to zero.
