I thought I should let you know about this as it may affect other applications although I have got around the problem by using a older version of FreeBSD (2.2.8). I was trying to use a couple of old 486 PCs to act as MBONE routers for a couple of subnets here at the university. I installed the latest version of FreeBSD (3.3) and rebuilt the kernel with multicast support. When mrouted was started it established a tunnel to our main MBONE router and all appeared to be working. However clients on the subnet could still not see MBONE traffic. Some experments showed that starting an MBONE application (SDR) on the FreeBSD system would then cause it to start forwarding MBONE traffic, it would then continue to work until the system was rebooted or mrouted was killed and restarted. Clearly some part of the multicast interface was not getting setup correctly. At that time FreeBSD 3.4 was released so I tried rebuilding one of the routers with this but the same effects were observed. I did some investigation and found out that the version of mrouted that comes with FreeBSD dated back to version 2.? of FreeBSD. I decided to rebuild one of the systems with FreeBSD 2.2.8, this cured the problem. I can only assume that there are some subtle differences in the multicast interface between release 2.? and release 3.? . If you need any further information please let me know.
