Hold up, what if R3 is a mischievous router that's ignoring the 'summary-only' command? Then we might see Client1 and Client2 in addition to the aggregate. Hmm, better double-check that 'summary-only' config.

Okay, got it! Since R6 is advertising the aggregate 10.64.0.0/12 with 'summary-only' enabled, that means it's not going to advertise the more specific Client1 and Client2 routes. So the answer has to be B) Only the aggregate.

Hmm, this is a tricky one. Let's see, with the 'summary-only' enabled, I would expect to see only the aggregate route on R7. But the question is asking about the routes received, not the routes on R7 itself. Gotta think this through carefully.
