Create overlay-backed NSX segments, also known as Application Virtual Networks (AVNs), for use with VMware Aria Suite components.

This procedure describes creating overlay-backed NSX segments. If you want to create VLAN-backed NSX segments instead, see Deploy VLAN-Backed NSX Segments.


Create an NSX Edge cluster for Application Virtual Networks, using the recommended settings, in the default management vSphere cluster. See Deploy an NSX Edge Cluster.


  1. In the navigation page, click Inventory > Workload Domains.
  2. Click on the management domain.
  3. Select Actions > Add AVNs.
  4. Select Overlay-backed network segment and click Next.
  5. Select an NSX Edge cluster and a Tier-1 gateway.
  6. Enter information for each of the NSX segments (Region-A and X-Region):
    Option Description
    Name Enter a name for the NSX segment. For example, Mgmt-RegionA01.
    Subnet Enter a subnet for the NSX segment.
