Re: igmp leave group message

There is no "leave group".
There is "include <NULL>" which means the host doesn't want to listen  
to anything.
Normally you wouldn't send such a message (I can't think of any  
reason you would)
So if you are listening to a group you are "Exclude NULL" or do not  
exclude anything.
To leave you change your interface filter state with a "TO_IN<NULL"

The TO_* messages tell the querier to check the other hosts on the  
network to
see if they are still interested in the specific group.
