10.11. I want to enable IP multicast support on my FreeBSD box, how do I do it? (Alternatively: What the heck IS multicasting and what applications make use of it?)

Multicast host operations are fully supported in FreeBSD 2.0 by default. If you want your box to run as a multicast router, you will need to load the ip_mroute_mod loadable kernel module and run mrouted.
