In a nutshell, it acts as a broker or dating service if you will. It
essentially allows the multicast source to
register with it and all multicast receivers the capability of determining
where all the multicast sources are
and be able to join the shortest path tree (SPT). Either the source or
receiver can join first.
It's common to run multicast in sparse-dense mode which "allows the router
to operate in dense or sparse
mode, depending on the existence of RP information from each multicast
group, and makes it much easier
to switch the network from dense mode to sparse mode (or vice versa) as
needed".
Quoted info is from Williamson - Developing IP Multicast Networks, pp 242.
