Yeah, that's exactly right. And I believe it's option B that's the correct answer here. Eliminating the need for a fully-meshed design is a key benefit of using BGP confederations.

Hold on, I think I remember this from my studies. Isn't the purpose of BGP confederations to break up a large AS into smaller, more manageable chunks? That would definitely help with the routing complexity.

Hmm, I'm pretty sure it has something to do with eliminating the need for a fully-meshed internal BGP design. That would make a lot of sense, since managing all those peer connections can get really complicated in large networks.

This is a tricky one. I've heard of BGP confederations before, but I'm not entirely sure about their exact function. I think it has something to do with managing large autonomous systems, but I'm not confident about the details.
