B and D. Wait, is this a trick question? I feel like the answer is just 'all of the above' and the real challenge is finding the trick.

I'm not sure about that. I think it's B and D.

Hmm, this is tricky. I'm gonna go with A and C. Seems like Level 1 and Level 2 are kept separate unless you explicitly configure otherwise.

So, it's important to understand how route advertisement works between IS-IS levels to ensure proper network connectivity.

That makes sense. Level 1 routes are not advertised to Level 2 routers unless wide-metrics-only is configured.

I think you're right, A and C are the correct statements. Level 1 and Level 2 routes are kept separate by default.

I think B and C are the right answers here. Level 1 routes are definitely advertised to Level 2 by default, and the wide-metrics-only setting blocks that behavior.

So, A and D are incorrect then. Level 1 and Level 2 routers do not advertise Level 2 routes into the Level 1 area by default, and Level 1 routes advertised as external routes into Level 1 are not advertised to any Level 2 routers by default.

I think C is also correct. With wide-metrics-only configured, Level 1 routes are not advertised to Level 2 routers.

I agree, B is correct. Level 1 routes are advertised to Level 2 routers by default.

A and C sound correct to me. Level 1 and Level 2 routers don't share routes by default, and if wide-metrics-only is on, Level 1 routes aren't sent to Level 2 either.

Yes, Level 1 and Level 2 routers behave that way with wide metrics.
