I thought it could be R4, but I guess not?

R1 is the PLR, so R2 makes sense.

Wait, why isn't it R3? That seems off.

I feel like R3 could be the MP too, but I lean towards R2 based on what we practiced.

I’m a bit confused about the facility bypass aspect. Does that change who the MP is? I need to think this through more.

I remember a similar question where R1 was the PLR, and R2 was the MP. It seems consistent with the concept of fast reroute.

I think the MP should be R2 since it's the next hop after R1, but I'm not completely sure.

This is a straightforward MPLS fast reroute question. Based on the information provided, the answer is Router R2.

The question is asking about the MP router when R1 is the PLR. I'll need to review my MPLS fast reroute knowledge to determine the correct answer.

Okay, got it. With facility bypass and link protection enabled, when R1 is the PLR, R2 becomes the MP. I'm confident this is the right answer.

Hmm, I'm a bit confused by the wording here. Let me re-read the question carefully and think through the MPLS fast reroute concepts.

This looks like a MPLS fast reroute question. I think I know the answer, but I'll double-check the details in the question to be sure.

I'm going with B) Router R2. It just makes the most sense to me based on the information provided. Now, if this were a question about fast food, I'd be all over it!

Haha, I bet the person who wrote this question was trying to trick us. The answer is clearly C) Router R3. It's the next-next-hop router, so it becomes the MP.

Yeah, that makes sense. Router R3 is the next-next-hop router.

I'm pretty sure the answer is B) Router R2. The MP is the router that combines the two backup paths, and in this case, it's the next-hop router from the PLR, which is R2.

Hmm, this looks like a tricky one. Since both LSPs have facility bypass and link protection enabled, I think the MP (Merge Point) would be the next-next-hop router, which is R3.
