Wait, wait, wait... did someone say 'router'? I thought this was going to be about cake recipes or something. *scratches head* Okay, let me focus here...

Ah, I remember learning about this in my BGP class. The route with the highest local preference wins, regardless of the AS Path length. C is the correct answer, no doubt about it.

I'm going to have to think this one through carefully. The local preference is the key factor here, but the AS Path lengths also play a role. Hmm, let me work this out step-by-step.

The third route has the highest local preference, so it should be the one that appears in the RIB-In. This seems like a pretty straightforward question.
