I think we might be looking at OSPF for the underlay since it's commonly used in data center fabrics, but I'm not entirely sure.

I'm a bit confused on this one. The fact that each room is its own fabric makes me think it might be iBGP, since that's used for routing within an autonomous system. But then again, the question is specifically asking about the underlay routing protocol, so I'm not sure.

I'm leaning towards OSPF as the answer. Each data center room is its own fabric, but they are still part of the same organization, so OSPF would make sense as the underlay routing protocol to connect them.

Okay, let me break this down. Since each room is its own fabric, that means they are separate network domains. And the question is asking about the underlay routing protocol, so I'm thinking the answer is eBGP, which is used for routing between autonomous systems.

Hmm, I'm a bit unsure about this one. I know iBGP is used for routing within an autonomous system, and eBGP is used for routing between autonomous systems. But I'm not sure which one would apply here since the question is about routing between data center rooms.

This seems like a straightforward networking question. I'll think through the key details - each data center has two rooms, and each room is its own fabric. The question is asking about the underlay routing protocol between the data center rooms.

I agree with Yuki, OSPF makes sense for this scenario.

I'm just gonna go with iBGP because it's the only one with 'BGP' in the name. That's gotta mean it's the right answer, right? *winks*

I think the underlay routing protocol is OSPF.

OSPF? Nah, that's more for a single administrative domain. With multiple data centers, eBGP is the way to go. It's the industry standard for this kind of setup.

RIP? Really? That's so outdated, it's practically a dinosaur. This is a modern data center design, we need something more scalable and efficient.

eBGP seems like the obvious choice here. Each data center room is its own fabric, so we need a routing protocol that can handle communication between these separate domains.

Definitely, eBGP can handle the communication between the different fabrics in each data center room.

Agreed, eBGP is designed for communication between separate domains like the rooms in each data center.

Yes, OSPF could work for routing within the same data center, but eBGP is better suited for communication between separate fabrics.

Wouldn't OSPF work as well for routing within the same data center?
