when to use a multicast address-family

When do its neccessary to enable muilticast address-familly and to form a
mBGP peer ????

when there is a BGP domain in between which supports only a unicast domain
functionality

say ,

AS100 ---------- AS200 --------- AS300

MDT will not form across a network that does not have multicast enabled

so is it ,

when AS 200 does not supports multicast

or the link between AS100 and AS200 dose not run multicast

or both

little confused
