Multicast routing with VLANs

[Eivind Hestnes]

Hi,

I'm trying to get mrouted to route multicast traffic between multiple 
VLANs on a FreeBSD 5.4-RC3 machine. Mrouted starts as expected, and 
according to /var/log/messages it's running - but the multicast routing 
itself don't work. While Googling, I noticed in kern/78821 
(http://www.freebsd.org/cgi/query-pr.cgi?pr=kern/78821) that FreeBSD 
fails to set the ALLMULTI flag on the parent device when using the 
if_em(4). I have tried to set the ALLMULTI flag manually, but with no 
further success - The flag won't set.

I need the multicast routing to get Norton Ghost work properly, and 
currently I'm a bit stuck..
