But wouldn’t RR1 need more sessions for full connectivity?

D sounds right. PE1 connecting to RR1 and PE2 fits.

I’m leaning towards C. PE2's sessions seem limited.

I feel option B makes more sense. RR1 should connect with both.

C) makes sense, PE2 only connects to RR2 and ASBR2.

Wait, how does PE1 only have two sessions? That seems off.

I feel like PE2 having two sessions is a common scenario, so option C could be correct, but I'm not entirely confident.

I practiced a similar question where RR1 had multiple sessions, so I might lean towards option B, but I need to double-check.

I think option A sounds familiar because it mentions ASBR2, but I can't recall if it really has three sessions.

I remember studying BGP sessions, but I'm not sure about the exact number of sessions for each router.
