Do the clients using this interface need to know the difference between multicast and broadcast in order to function correctly? If so, then why not have this interface resolve the amibiguity? That can be done by checking the destination address (dl_dest_addr_*) when you see that dl_group_address is set. -- James Carlson, Solaris Networking <james.d.carlson at sun.com> Sun Microsystems / 35 Network Drive 71.232W Vox +1 781 442 2084 MS UBUR02-212 / Burlington MA 01803-2757 42.496N Fax +1 781 442 1677
