Hmm, I'm not sure about the correct answer here. I'd have to double-check the OSPF IP FRR behavior in this topology. Maybe I should have paid more attention in my OSPF class instead of doodling during the lectures.

I agree with you, Donette. BFD is important for fast fault detection.

I think option C is true because BFD can quickly detect faults.

I think the correct answer is D. If the link between R1 and SI is disconnected, R1 should directly use the backup path to forward packets to R3. OSPF IP FRR is designed for this kind of scenario.
