There are different combinations of supported switches per speed. For example, constructing a network of 400GbE leaf-spine connectivity requires the network owner to pick switches and cables that can support those rates.Jul 5, 2018 · Let's dive into some more detail. So based on the Clos diagram above, and based on only 2 levels of crossbars, we can produce a 3 stage Clos. By 3 stage I mean that the leaf's are stage 1 and 3 and the spine is stage 2. Furthermore, each leaf is connected to each spine, with there being no connectivity between spines. The Layer 3 Leaf and Spine (L3LS) topology is the foundation of Arista’s Universal Cloud Network Architecture. At a high level the Layer 3 Leaf Spine (L3LS) is simply a collapsed 2-Tier topology comprised of spine and leaf switches. This simple design, when

Please explain the benefit of Spine/leaf architecture over 3 tier architecture. One of the main benefits is the predictable latency between nodes in the fabric. In a spine/leaf topology there are exactly four links separating one end station from any other end station connected to that fabric regardless of where it is connected to the fabric.The leaf-spine architecture enables all ports on a spine switch to support connections to leaf switches, instead of to other spine switches. Additionally, it enables connections to …
