No way, it should send it to all connected routers!

Wait, can it really discard updates? That seems odd.

I think it just discards duplicates, right?

I think router B just sends the update to router D. I remember we discussed how routers handle updates, but this one is tricky!

I feel like router B should propagate the update to both routers C and D, but I’m not confident about the specifics of BGP behavior in this scenario.

I think router B might just propagate the update to router D, but I'm not entirely sure. It feels like there was a question similar to this in our practice tests.

I remember something about BGP updates being discarded if they are duplicates, but I can't recall if that's the case here. It’s a bit confusing.

Hmm, I'm not too sure about this one. I know Terraform has a lot of different concepts, but I'm not sure which ones are considered the most important.
