I'm not sure, but I think the next hop could also be the IPv6 global address of router D.

I agree with Evette, because in iBGP the next hop will always be the IPv6 link-local address of the router facing towards the eBGP neighbor.

I disagree, I believe it is the IPv6 link-local address of the router A interface towards router D.

I think the Next Hop for prefix 2001:DB8:A:401::1/128 on router B is the IPv6 link-local address of the router D interface towards router A.

I think the answer might be C) The IPv6 global address of router A because it's the source router.

But wouldn't the next hop be the interface of the next router in the path?

I hope the exam doesn't have too many of these iBGP questions. I'm starting to get a headache just thinking about it.

Wait, did they say all router-IDs are properly configured? That's a relief, I was worried we'd have to troubleshoot that too.

Hmm, IPv6 Next Hop, eh? I remember learning about this in class, but let's see if I can put it into practice.

Ah, good ol' iBGP, the bane of every network engineer's existence. But I think I've got this one figured out.

This question seems pretty straightforward, but I'm still a bit unsure about the iBGP configuration and how it affects the Next Hop. I'll have to think this through carefully.
