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 and later releases support 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, 3.6.0 .

Tenant Network onboarding services are supported on both 3-stage and 5-stage Clos topologies, allowing connectivity for devices connected to the fabric, such as compute (servers), storage, and external routers or gateways. For information on configuring and managing tenants, see Tenants (Fabric Mode).

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