Automating Clos Fabric Provisioning

There are four steps to automating Clos Fabric Provisioning, whether it is a three-stage, five-stage, or Non-Clos Small Data Center topology: Create the fabric, register the devices, validate and add the devices, and provision the configuration on the devices.

  1. Create the Fabric. Modify the default Fabric settings if necessary.
  2. Register devices in the inventory with discovered Assets as follows:
    • Device details such as model, firmware, ASNs
    • Physical Interfaces, VEs
    • Logical Interfaces such as VLANs, BDs, port-channels
    • VRFs, BGP, MCT, EVPN, overlay
    • Stored device credentials, eliminating the need to specify device credentials in other provisioning commands
  3. Add devices to the Fabric.
    • Clos physical topology (physical connections as per EVD) between devices is validated.
    • Based on device roles and topology, an intended configuration is generated.
  4. Configure the Fabric and provision the underlay and overlay configuration on the devices.
    • Push the Laayer 2 and Layer 3 configurations necessary to form an IP Fabric down to the SLX devices.
    • Validate the configuration pushed to the devices.
