As a network engineer, I've seen some crazy multicast behavior in my day. This question is like a multicast riddle wrapped in an enigma!

Option B is just too simple. In a PIM ASM network, you know the multicast routing is gonna be a complex dance between the routers. I'm going with option A.

It's always interesting to see how the routers handle multicast traffic in different scenarios.

Yeah, option B does seem a bit too simple for the complexity of multicast routing.

I think option A makes sense, both Router B and Router C would propagate a PIM (*, G) Join to the RP.

I agree, multicast routing can be quite complex in a PIM ASM network.

Haha, I bet the right answer involves some obscure networking voodoo that only the exam writers know about. Good luck to us all!

I'm torn between options A and D. I think it really depends on Router D's RPF table, as mentioned in option D.

I agree with you, it could also depend on the next hop for RP in Router D's RPF table as mentioned in option D.

I think option A is correct because both Router B and Router C will propagate a PIM (*, G) Join to the RP when a receiver joins.

Option A seems to be the correct answer here. Both Router B and Router C will propagate a PIM (*, G) Join to the RP when a receiver joins the multicast channel in a PIM ASM network.

Exactly, it helps in maintaining the multicast distribution tree in the PIM ASM network.

That makes sense, it ensures that the RP receives the necessary information when a receiver joins the multicast channel.

But what if the RP is closer to Router C? Wouldn't it make sense for only Router C to propagate the Join?
