Isn't IGMP(*, G)Join more relevant here? Just saying!

Wait, why would Router D send a PIM Hello? That seems off.

I’m leaning towards the PIM (*, G)Join option, but I might be mixing it up with IGMP messages from earlier studies.

I feel like it could be a PIM prune message since Router F switched to the Source Path Tree, but I can't recall the specifics.

I remember a practice question where Router D had to send a PIM Join when a new receiver joined. Could it be the same here?

I think Router D would send a PIM Join message, but I'm not sure if it's (*, G) or (S, G).

Okay, I've got a strategy - I'll focus on what happens when the receiver joins the multicast group and the source tree is used.

I agree with Gayla, because Router D will send a PIM(*, G)Join message towards Router E.

I think it's D too. Switching to the source path tree means Router D needs to prune the shared tree and join the source-specific tree.
