Router R2 is the MP because it’s the first to bypass.

R4 and R5 aren't even in the path, so they can't be it.

R1 can't be the MP since it's the PLR.

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.
