I agree with B, but I can see why some might think C.

Wait, why would it go to all routers? Seems off.

Definitely option B! That's how iBGP works.

I thought updates were only sent to directly connected peers, so maybe it's just R2 and R3, like in option B?

I practiced a similar question, and I feel like it might just go to R2 and R3, but I can't recall the exact details.

Alright, time to apply my BGP knowledge. I'll analyze the options and eliminate the incorrect ones to find the best answer.

I've got a good handle on iBGP, so I'm confident I can figure out the right way router R1 would handle this update.

Ugh, BGP can be so confusing sometimes. I'll have to review the iBGP rules and propagation before answering this.

I'm a little confused by this question. The different plan names sound similar, and I'm not sure I fully understand the differences between them. I'll have to review my notes and try to distinguish them more clearly before answering.

Option C, no doubt about it. I'm just hoping the test doesn't ask me to draw the full mesh diagram from memory. That would be a real brain-teaser!

I'm leaning towards B, but I'm also curious if the answer has something to do with the 'ISP 2' part of the question. Maybe it's not as straightforward as it seems.

Haha, trick question! In a full iBGP mesh, the update should be sent to all routers in ISP 1. C is the way to go.

I'm not sure about this one. My gut tells me it's D, but I'd need to double-check the BGP behavior in a full mesh topology.

Option C seems the most logical choice, as in a full iBGP mesh, the BGP update should be sent to all routers in the ISP 1 network.
