I thought it would be B, but A makes sense.

Wait, why would it send a PATH Tear to R6? Seems odd.

PATH Error messages are for different scenarios, not this one.

Router R3 will send a PATH Tear message to clear the session.

I remember that PATH Tear is used to clear sessions, but I can't remember if it goes to R1 or R6 in this case. I hope I picked the right one!

I’m leaning towards option A, but I’m a bit confused about the difference between PATH Tear and PATH Error messages.

This question feels familiar. I practiced one where the router had to send a PATH Tear, but I can't recall if it was toward R1 or R6.

I think I remember that when an RSVP session times out, the router sends a PATH Tear message to clear it, but I'm not sure which direction it goes.

I've got a good feeling about this one. The question is asking what R3 will do, and based on the RSVP message flow, I believe the correct answer is to send a PATH Tear message toward the upstream router, which is R1.

Okay, let's see. Since the RSVP session has timed out on R3, it needs to clear that session. I think the key is figuring out which direction the PATH message came from originally.

Hmm, I'm a bit unsure about this one. I'll need to review my RSVP protocol knowledge to figure out the right answer.

This looks like a pretty straightforward RSVP session state question. I'll need to think through the RSVP message flow to determine the correct action.

I agree with Georgiann, A seems like the correct answer.

But sending a PATH Tear message toward router R6 makes more sense in this scenario.

Hmm, I think R3 should send a PATH Tear message toward R6 to clear the RSVP session. It makes sense to notify the downstream router directly.

User2: But wouldn't sending a PATH Error message to R6 also work?

User1: I agree, sending a PATH Tear message to R6 seems like the right move.
