Maybe a quick word on it in the draft would be useful. I am also wondering how the (S,G) target list is populated in the case you have a Join(S,G) coming from an external peer (and (S,G) entry is then created), but you already have a (*,G) entry. Is target list copied from (*,G) to (S,G), and (*,G) Joins update (S,G) target list ? Thank you.

Maybe a > quick word on it in the draft would be useful. I think it's been explained on the list... Isidor Kouvelas originally brought up the problem 2 IETF meetings ago. In short, it solves the problem of knowing whether to forward packets towards the root or not when you're receiving data on an (S,G) branch. > I am also wondering how the (S,G) target list is populated in the case you > have a Join(S,G) coming from an external peer (and (S,G) entry is then > created), but you already have a (*,G) entry.
