But the Next Hop should be the link-local address of the next hop router, which is D.

Haha, I bet Arthur forgot that iBGP sessions use link-local addresses, not global addresses. The correct answer is definitely B!

Hmm, I'm pretty sure the answer is C. The IPv6 global address of router A should be the Next Hop, since it's the originating router for the prefix.

I agree with Ayesha. The configuration on router A shows that the eBGP session with router D is established using the link-local address, so the Next Hop should be the link-local address of the router A interface.

The correct answer is B. The Next Hop for prefix 2001:DB8:A:401::1/128 on router B should be the IPv6 link-local address of the router A interface towards router D.

Because in iBGP, the next hop is the link-local address of the router advertising the route.

But why not A) The IPv6 link-local address of the router D interface towards router A?
