Abstract
A packet forwarding network may include spine and leaf switches that forward network traffic between end hosts. The packet forwarding network may be implemented on multiple network racks in a rack-based system. A controller may control the underlying spine and leaf switches to form on-premise virtual private cloud (VPC) resources. In particular, the controller may form enterprise VPC (EVPC) tenants, each having a virtual router that performs routing between different segments within the corresponding EVPC tenant. The different segments may separately include web, application, and database servers, as end hosts. The controller may form a system VPC tenant having a virtual system router that performs routing between different EVPC tenants. A segment in an internal VPC tenant formed by the controller and/or an external VPC tenant formed by the controller may provide external network access for one or more of the EVPC tenants.
