I'm not sure about this... can someone explain why link-local is preferred?

Totally agree with Luisa, link-local is the way to go!

Wait, why would it be a global address? That seems off.

I think it's actually the global address of router A.

It's definitely the IPv6 link-local address of router A towards router D.

I recall that in iBGP, the Next Hop is typically the router that sent the route update. So, I’m leaning towards the link-local address of router A, but I could be mixing up some details.

This question feels similar to one we practiced where we had to determine the Next Hop based on the iBGP configuration. I think it might be the global address of router A, but I'm not completely confident.

I think the Next Hop should be the IPv6 link-local address of router A since it's the one advertising the prefix, but I need to double-check that.

I remember that the Next Hop in iBGP usually points to the router that originated the route, but I'm not entirely sure how that applies here with link-local addresses.
