The MP is Router R2.

I believe the MP is R3 because it’s the last router in the path before the destination, but I need to double-check my notes.

I’m a bit confused about the facility bypass part. Does that affect which router becomes the MP?

I remember a similar question where the PLR was also the first router in the path. Could it be R1 again?

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