I’m confused. All options sound plausible, but D feels the least accurate.

I feel C is the answer. MP-iBGP sessions are crucial for PE routers.

No way, B is true. They need to share info directly for efficiency.

I’m leaning towards B being false. Direct exchange seems risky.

Wait, so the ASBR is like the bouncer of the AS, checking IDs and stamping hands? I'm going with option A.

I feel like option C is definitely correct because MP-iBGP is essential for exchanging those prefixes, but I’m not entirely sure about the others.

I practiced a similar question where we discussed MP-iBGP and VPN-IPv4 prefixes, so I'm leaning towards option A being true.

I recall that ASBRs do exchange information, but I'm not sure if it's specifically as VPN-IPv4 routes in option D.

This question is testing our understanding of the VPRN inter-AS models, so I'll need to make sure I have a solid grasp of the differences between them.
