Wait, can we really create over two million segments? That's wild!

IPsec over GRE won't handle that many segments, right?

Dark fiber? Really? That seems too basic.

OTV is great for Layer 2 over Layer 3!

Dark fiber seems like a physical solution, but I doubt it meets the Layer 2 stretching and logical segmentation needs outlined in the question.

I practiced a similar question where GRE was mentioned, but I don’t think it isolates STP traffic effectively like the others might.

I think OTV could be a good option since it stretches Layer 2 over Layer 3, but I’m not confident about the scalability for two million segments.

I remember studying about VXLAN and how it can create a large number of logical segments, but I'm not entirely sure if it fits the unicast-only requirement.

IPsec over GRE might be a good option here. It can handle the unicast-only, Layer 3 circuit requirement, and the GRE tunneling should let me isolate the STP traffic.

VXLAN VPN seems like it could work, but I'm not sure if it fully meets the requirement to "stretch the Layer 2 connection." I'll need to double-check the details on that one.

Okay, I think I've got this. The key is isolating the STP traffic and creating a ton of logical network segments. I'm leaning towards OTV for this.

Hmm, I'm a bit confused by the "stretch the Layer 2 connection over the tunnel" part. I'll need to review my notes on different tunneling protocols.
