Hmm, I'd go with A) Port lockdown on internal self IP is set to Allow None. Sounds like the culprit.

B) Route is NOT assigned to internal self IP. Definitely the issue here.

I vaguely recall something about tagged versus untagged VLANs affecting connectivity. Could that be the issue here?

I'm not entirely sure, but I feel like the VLAN settings could play a role here. Is it possible that the internal interface VLAN is set to untagged?

I think there was a practice question about routes not being assigned; that might be a reason for the ping failure too.

I remember something about port lockdown settings; could it be that the internal self IP is set to Allow None?

Good point, Emily. I think that's the most likely cause based on the information provided. I'll make sure to double-check the routing configuration.

I'm leaning towards option B - if there's no route assigned to the internal self IP, that would explain why it's not responding to ping.

I'm a bit confused on the port lockdown setting. Does that mean the self IP address can't be pinged?

Okay, let's see. The key here is understanding the default settings and how the internal self IP address should be configured.
