i've read several books which have discussed the entries in the multicast
routing tables - (S,G) and (*,G) entries. i understand that the S = source
and G = group, but what i just have not been able to grasp (for reasons
unbeknowst to me.........perhaps the drugs), the difference between the two
and how they relate to sparse and dense mode. can someone explain this in
simple terms so my delicate brain can understand the relevance? i seem to
remember that they have different meanings in dense mode and sparse
mode.......

TIA
