The traditional, three-layer network design.

A more direct path for server-to-server communication is achieved with “spine-leaf” architecture. In such a design there is a high density of fiber connections between leaf and spine switches which facilitates east-west traffic in support of “any-to-any” network connectivity. Another trend is a need for upgradable cabling infrastructure. Upgradeability …Cisco Nexus 9364C Switch.

With the shift to a leaf-spine architecture, the overall design of the cabling infrastructure is also experiencing a shift: Many large data centers are transitioning to EoR (end-of-row) deployments and structured cabling. In this design, switches are placed in a cabinet and connected to servers across an entire row …The spine-and-leaf network architecture transcends the limitations of the traditional three-tier network architecture, delivering high bandwidth and low latency for server-to-server communications. A standard method of connecting a spine-and-leaf network employs breakout cassettes and a dense web of fiber cross-connects, but this …Remote leaf switches learn external subnets from router with the next-hop of the Router SVI. The remote leaf advertises the externally learnt prefixes to spines through the MP-BGP VPNv4 session between RLs and spines. Spines in the ACI main DC act as a BGP Route Reflector (RR) for both remote leaves and Local leaves. This white paper covers background and definitions of Clos-based spine-and-leaf IP fabrics; contrasts scale-out and scale-up designs, including the use of chassis devices in spine-and-leaf fabrics; explains scaling steps and why there are size constraints on spine-and-leaf fabrics, and describes two basic scaling considerations: contention and ...
