I’m confused about whether the LSPs are shared or dedicated. If they’re dedicated, then it could be 200, but if they’re shared, maybe just 2?

I practiced a similar question where we had to calculate LSPs for a different number of services. I think it was 2 LSPs for a pair of networks, but this one seems trickier.

I’m not entirely sure, but I feel like the number of LSPs could be related to the number of services. Maybe it’s 200 since each service might need its own LSP?

I think we might need to consider how VPLS services are structured. I remember something about needing multiple LSPs for redundancy.
