Understanding Underlay Management

An underlay network is the physical infrastructure on which an overlay network is built. An overlay network is built on top of and is supported by an underlay network’s physical infrastructure. Starting with release 5.0.1, Contrail supports underlay network management. The existing Contrail configuration node can provide intent driven automation capabilities on physical network elements such as ToR and EoR switches, Spines, SDN gateway, and VPN gateways in the data center. In addition, you can perform basic device management functions such as device discovery, device import, image upgrade, device underlay configuration, and topology discovery from the node.

Benefits of Underlay Management

  • Enables basic device management functions from the Contrail configuration node.

  • Enables underlay network automation.

  • Supports zero touch provisioning (ZTP) of factory-default devices to form an IP Clos network.

    Note:

    ZTP allows you to provision new devices in your network automatically, with minimal manual intervention.
