Right! So, C seems balanced with 2 BGP and 1 MP-BGP.

I feel like option D makes sense too. Two BGP sessions for the sites.

I'm a bit confused about the total count. Do we need to account for both the PE-CE and PE-PE connections separately? I hope I remember the right formula!

This question feels similar to one we practiced where we had to count sessions based on the number of connections. I think we might need one MP-BGP session for the dual-homed site.

I remember something about MP-BGP sessions being required for VPNv4 routes, but I'm not sure how many we need here.

I think we need to consider the number of customer sites connected to PE-1. There are two sites, so maybe that means two BGP sessions?
