Huawei H12-831_V1.0 Exam - Topic 3 Question 73 Discussion

On the OSPF network shown in the figure, the cost values of links are marked, and OSPF IP FRR is enabled on R1. Which of the following statements are true?
B) If SI is powered off, R1 directly uses the backup path to forward packets to R3. and C) If BFD (with default detection parameters) is enabled on the entire network and the link between R2 and SI is disconnected, R1 can quickly detect the OSPF adjacency fault. and D) If the link between R1 and SI is disconnected, R1 directly uses the backup path to forward packets to R3.
A) No backup path can be established between R1 and 10.0.3.3/32.

D is true, R1 can use the backup path if the link goes down.

Wait, can R1 really use the backup path in D? That seems off.

I disagree with B, R1 won't just switch to the backup path like that.

I vaguely remember that if R1 loses its direct link to SI, it should be able to use a backup path to R3, but I’m not 100% sure about the specifics.

I feel confident about BFD helping with quick detection of faults, especially with default parameters, but I need to double-check how that interacts with OSPF.

I think I practiced a similar question where R1 had to switch paths, but I can't recall if it would use a backup path if SI goes down.

I remember studying OSPF and the concept of backup paths, but I'm not entirely sure if R1 can establish one to 10.0.3.3/32.

This is a good opportunity to apply my knowledge of OSPF and network redundancy. I'll methodically work through each statement and evaluate it based on the information provided.

I'm a bit confused by the wording of the question. I'll need to read through it a few times and make sure I understand the details before selecting the correct answers.

Okay, I think I've got a handle on this. The key is understanding how OSPF IP FRR works and how it affects the backup paths in this specific network scenario.

Hmm, the question is asking about OSPF IP FRR, which I'm not too familiar with. I'll need to review my notes on that feature before attempting to answer.

This looks like a tricky OSPF question. I'll need to carefully analyze the network topology and the OSPF IP FRR configuration to determine which statements are true.

That makes sense, Donette. Option D could be true in that scenario.

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 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.

But what about option C? Wouldn't BFD help in quickly detecting the OSPF adjacency fault?

I think so too, if the link between R1 and SI is down, using the backup path to R3 makes sense.
