Spine and leaf architecture.

Sep 19, 2020 · Spine and leaf architecture cisco. Leaf switches mesh into the spine, forming the access layer that delivers network connection points for servers. Each leaf switch connects to every spine switch. As a result, there’s no need for interconnections between spine switches. A spine-leaf architecture is a data center network topology that consists of two switching layers—a spine and leaf. The leaf layer consists of access switches that aggregate traffic from servers ...He wants a spine/leaf architecture. The easiest way would be to use ACI but he doesn't want it (and it won't happen).
