A fully loose LSP MtoR6" is enabled with FRR protection. All links have the same cost. After the link between R2 and R4 goes down, FRR protection repairs the LSP and traffic traverses on R1-R2-R7-R8-R4-R6. By default, which of the following about this LSP on an Alcatel-Lucent 7750 SR is FALSE?

Old paths get torn down after the new ones are set, that's standard.

CSPF needs to be enabled for optimal paths, right?

Wait, are you sure about that? Sounds off.

Totally agree, that's how it works!

The LSP will switch to R1-R3-R5-R6 after the resignal timer expires.

I remember reading that MBB switching is a thing, but I'm not clear if it applies to option D in this case. It feels like it could be misleading.

I'm a bit confused about CSPF; I thought it was necessary for finding optimal paths, but I can't recall if it's required in this specific scenario.

I think option A might be true because I remember something about the resignal timer, but I'm not completely sure how it works in this context.

I practiced a similar question where the old primary path was torn down after a new one was established, so I feel like option B is likely correct.

I think the key here is understanding the difference between evaluating the controls (process-based) and evaluating the actual performance (measurement-based). Based on that, I'm going to go with B as my final answer.
