I’m not sure about this. Can PCE really handle all that info?

Establishing BGP sessions with R3 and R4? That sounds complicated...

Wait, why not just go with B? Seems simpler.

I think option C is the best choice. BGP-LS is key for this.

I lean towards option C because BGP sessions can provide detailed traffic engineering info, but I’m not completely confident.

I feel like I might have seen a similar question where establishing IGP adjacencies was the answer, but I can't recall the specifics.

I'm not entirely sure, but I remember something about BGP-LS being important for PCE. Maybe option D is the way to go?

I think establishing IGP adjacencies with routers R1 and R2 might be the right choice since it seems like a common method for gathering topology info.

This question seems straightforward, but I want to make sure I understand the requirements correctly. I'll need to identify the resource type causing the issue, and do it quickly. Let me think through the options carefully.
