Surprised that 'discard-unknown' isn't the first choice!

I think a MAC filter is a better option here.

I think the 'discard-unknown' feature might be the right choice since it limits MAC learning, but I need to double-check my notes on that.

I’m a bit confused about whether an IP filter would actually help with FDB issues. I thought it was more about MAC addresses in this context.

This question feels similar to the practice ones we did about MAC learning and filters. I think applying a MAC filter could be a good option.

I remember we discussed how disabling learning on SAPs can help prevent FDB instability, but I'm not entirely sure if that's the best approach here.
