Spine and leaf architecture

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.
