I doubt E. B is more logical for stability.

I feel E could be right too, only eBGP neighbors.

But A could cause issues. B is safer.

I’m leaning towards A. Why not share with all?

Agreed, B makes sense. Avoids loops.

I think it's B. Router A won't send it back to router B.

Definitely not D), that's not how BGP works.

Wait, so it doesn't go back to router B? That seems odd.

It's B) for sure, can't send it back to the source.

B) All routers with which it has a BGP session, except the router it received the update from, which is router B. Duh, it's the only one that makes sense. Unless, of course, the question is a trap...

E) Only eBGP neighbors. Wait, what? I thought this was an iBGP update. Someone's trying to trick us here.

C) All routers with which it has a BGP session, except the router it received the update from, which is router C. Gotta love these tricky BGP questions!

I feel like it’s definitely not A, but I’m torn between B and C. I need to remember which router A received the update from.

I practiced a similar question where the update was only sent to eBGP neighbors. I wonder if that applies here too.

I'm feeling pretty confident about this one. BGP update propagation is something I've studied a lot for this exam.

I've got a strategy for these types of BGP questions. Let me walk through the options and see which one fits best.

Ugh, BGP questions are the worst. I'm going to have to really focus on this one to get it right.

I’m not entirely sure, but I remember something about eBGP and iBGP sessions. Could it be E?

B) All routers with which it has a BGP session, except the router it received the update from, which is router B. Seems like the most logical answer.

I think the answer might be B, since BGP usually doesn’t send updates back to the router it received them from.

D) All routers with which it has a BGP session, except the router it received the update from, which is router D. I'm pretty sure that's the correct one.
