Hi all,

Is there any reason to send out a query in fast-leave is enabled on the interface?? Enabling fast-leave allows deleting the cache immediately on receiving a leave. If the cache is deleted immediately, hosts on the interface will see traffic loss, which makes me think that fast-leave is enabled when the interface is gauranteed to receive a leave when the last host goes away or there is only one host on the interface. So does it make any sense in sending out a query on receiving a leave if fast-leave is enabled??
