The private virtual interface allows VMware HCX migration and network extension traffic to flow over the Direct Connect connection between your on-premises or cloud source environment and your destination SDDC.

Caution:

Ensure the IP Address Range configured does not overlap with the VMware Cloud on AWS management subnet CIDR block or any other IP range already in use for services in VMware Cloud on AWS. Overlap can cause routing and network reachability issues for those other components.

Prerequisites

  • The AWS Direct Connect with Private Virtual Interface is supported on VMware Cloud on AWS SDDC backed by NSX-T networking.

  • The SDDC must be configured to use the Direct Connect Private Virtual Interface.

    See Configure AWS Direct Connect Between Your SDDC and On-Premises Data Center.

  • A private subnet that can be reached from on-premises over the Direct Connect with Private VIF or with Transit VIF, ideally reserved for VMware HCX component deployments.

Procedure

  1. Log in to the VMware Cloud on AWS console at vmc.vmware.com.
  2. Select your organization and data center (SDDC).
  3. Select Add Ons.
  4. Click OPEN HCX on the HCX card.
  5. Navigate to the SDDC tab and click OPEN HCX.
  6. Enter the [email protected] user and credentials and click LOG IN.
  7. Navigate to Infrastructure > Interconnect.
  8. Click the Network Profiles tab.
  9. In the Direct Connect network profile template, click Edit.
  10. Enter the private IP address ranges reserved for VMware HCX.
  11. Enter the Prefix Length and the Gateway IP address.
    Note: A prefix length between 24–30 is recommended. HCX does not support prefix length 0, 31, or 32.
  12. Click Update.
    Important:

    Either directConnectNetwork1 or externalNetwork must be configured as the Uplink Network Profile in the Compute Profile. The Mgmt-app-network profile cannot be used and can result in a Service Mesh deployment failure.

Results

When the Service Mesh is deployed, it uses the Uplink Network Profile, private IP addresses assigned by the user. The assigned IP addresses are reachable over the AWS Direct Connect.
