Hi William, We assessed this concern at the time of design it self , so made the initial discovery (broadcast/multicast message ) time as configurable in secs , by default `DTM_INI_DIS_TIMEOUT_SECS=5` is secs see ditmd.conf.
This means the broadcast/multicast message will comedown after initial discovery / after node joining the cluster. So no issue. -AVM On 7/25/2014 7:05 PM, William R Elliott wrote: > > Thanks very much for this information. > > I do have another question concerning broadcast/multicast > information.
