Underlays identify the transport networks that provide connectivity between NSGs, e.g. the Internet or a carrier MPLS VPN. The modelling of an underlay is required when using multiple disjoint underlays that are interconnected via one or more NSG-UBRs. The underlay object is used at the NSG Control uplink and at the NSG-UBR Underlay uplink. If no underlays are defined a default underlay is used.


  • name (Mandatory): Name of the underlay
  • last_updated_by: ID of the user who last updated the object.
  • description: Description of the underlay
  • underlay_id: Used to identify and make a distinction between different Underlays with an autogenerated integer.
  • entity_scope: Specify if scope of entity is Data center or Enterprise level
  • external_id: External object ID. Used for integration with third party systems
