There are two waring multicast protocols... the one originally designed for BSD (mrouted), and Cisco's more modern mcast protocols. Until the protocols are reconciled you aren't going to be seeing much in the way of high-bandwidth multicasting. -Matt Matthew Dillon To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-security" in the body of the message
