Together, they create an architecture that is highly standardized across deployments.Jan 6, 2020 · Historically, web-scale providers have built their MSDC networks with a spine-leaf Clos-like Layer 3 IP fabric architecture. These basic designs started with a two-tiered spine-leaf Clos design with 1G servers and 10G uplinks between spine and leaf, as shown in Figure 1. The IP underlay network building block is arranged in a Clos-based fabric topology. The underlay network uses EBGP as the routing protocol in place of a traditional IGP like OSPF. You can use other routing protocols in the underlay protocol in your data center; the usage of those routing protocols is beyond the scope of this document.The spine-and-leaf architecture is a network topology commonly used in data centers to provide high bandwidth, low latency, and scalability. In this architecture, network switches are organized into two layers: the spine layer and the leaf layer. In a spine-and-leaf architecture, each leaf switch is connected to every spine switch, and the connections …

For instance, Remote Data Center sub-module of the Enterprise Remote Locations module, might follow the Spine-Leaf Network Design. What is spine-leaf architecture? Spine-leaf, or leaf-spine, is a two-layer network topology composed of spine and leaf switches. A spine-leaf architecture helps data center networks reduce network latency and hop count and improve network efficiency. The Leaf-and-Spine architecture (also known as a Clos Network) is a specific design used within data centers, and it’s an integral part of Cisco’s Data Center networking solutions. Due to its non-blocking design, the architecture offers high levels of redundancy, scalability, and predictable latency.
