Fabrics (Fabric Mode)

A fabric denotes a collection of interconnected devices in a topology on which underlay and overlay networks are configured.

XCO 3.2.0 supports building and managing small data center (non-Clos) fabrics and 3-Stage and 5-Stage IP Clos fabrics based on a BGP underlay with a BGP or EVPN overlay.

• Non-Clos topology involves one to four interconnected racks. Each rack consists of a pair of leaf nodes or border leaf nodes.
• 3-Stage Clos topology involves a spine layer and leaf or border leaf layer. The border leaf can be single-homed or dual-homed.
• 5-Stage Clos topology involves a super spine layer, spine layer, and leaf or border leaf layer. The leaf or border leaf can be single-homed or dual-homed.

For more information on IP fabric topologies, see ExtremeCloud Orchestrator CLI Administration Guide, 3.2.0 .

You can use the Fabrics page in XCO to configure and manage IP fabrics.
