Fabric Lifecycle Management
You can onboard, configure, and manage a set of devices, and physical network functions (PNF) in Contrail Networking as an IP fabric. A fabric is a set of devices, and PNFs that fall under the same data center administrator responsibility area. The fabric is linked to different role-based access control (RBAC) profiles for ease of administration and management.

Contrail Networking helps you provision both greenfield and brownfield devices to form IP Clos networks. You can bring up all factory-default greenfield devices using zero-touch-provisioning to form an operational IP Clos network with underlay connectivity. However, unlike greenfield devices, brownfield devices are manually provisioned before device onboarding.
