I was also considering B, but option D also caught my eye. Limiting IP learning to the subnet could help prevent any issues with the MAC address change, since the traffic would be confined to the local subnet.

Hmm, I'm leaning towards option B. If the MAC address change is causing issues, setting L2 Unknown Unicast to Flood might help by ensuring that the traffic gets delivered even with the MAC address change.

Let's go with option B then. It seems like the best solution.

That's true, ARP flooding could also be beneficial in this situation.

But wouldn't enabling ARP flooding also help with the MAC address change?

Yeah, I agree. The exhibit doesn't provide much context, so it's hard to know exactly what's happening. But I think the key is that the MAC address change is causing some kind of problem in the network.

This question seems a bit tricky. I'm not sure if I fully understand the issue with the standby interface using its built-in MAC address.
