D, definitely D. I mean, come on, R1 has to do all the work here. Those other options are just a warm-up for the main event. I bet R1 is doing pushups between router hops just to stay ahead of the game.

Yeah, R1 really has to be on top of things in this situation.

But D is crucial, R1 signaling an alternate path is key for failure propagation time.

I think A is also important, R4 needs to send a PATH Error message quickly.

C) The time router R4 takes to send a RESV Error message to the head-end router. This would be my pick, as it's the last step in the failure notification process before the head-end can react.

That's important too, but I think sending the RESV Error message is the final step in the process.

But what about the time it takes for R4 to detect the RSVP Hello message timeout from R6?

But what about the time router R1 takes to signal an alternate path through router R3? Could that also affect the failure propagation time?

I agree with Melvin. The faster router R4 sends the PATH Error message, the quicker the failure can be propagated.

I think the answer is D. R1 has to do the heavy lifting here, so it's the key factor in the failure propagation time. Though, I do wonder if the routers have enough coffee to keep them running at peak performance.

I hope the routers are well-caffeinated for this task!

B) The time router R4 takes to detect RSVP Hello message timeout from router R6. Detecting the failure is the first step, so this option should have the most impact on the failure propagation time.

That makes sense. Option B is likely the most important factor in failure propagation time.

Yes, I agree. Once the failure is detected, the propagation time can start.

D) The time router R1 takes to signal an alternate path through router R3. This seems like the most logical answer, as the failure propagation time would depend on how quickly the head-end router can establish a new path.
