VMware Cloud Director

Issue/Introduction

In the Cloud Director UI, you may encounter an issue where IP Spaces display a "Critical" general status. When this occurs, you are unable to perform modifications, such as changing or adding new IP ranges to the affected IP Space.

Environment

  • Cloud Director 10.6.x

  • NSX-T

Cause

This issue is caused by a configuration conflict. A static route is being advertised from NSX-T that uses the same CIDR as the IP Space configured in Cloud Director. This results in overlapping IP addresses, which Cloud Director identifies as a critical error, locking the configuration.

Resolution

To resolve this conflict, you must temporarily disable route advertisement in NSX-T to "unlock" the configuration in Cloud Director, make your intended change, and then re-enable route advertisement.

  1. Log in to the NSX-T UI and navigate to the T1 gateway backing the Cloud Director Edge Gateway.

  2. Go to the Route Advertisement settings for the T1 gateway.

  3. Temporarily disable advertisement for static routes. You can typically do this in one of two ways:

    • Disable the All Static Routes toggle.

    • Alternatively, go to Set Route Advertisement Rules, Edit the relevant rule, and uncheck Static Routes.

  4. Log in to the Cloud Director UI.

  5. Navigate to Edge Gateways and select the affected edge. Refresh the webpage.

  6. Verify that route advertisement for the conflicting network has been removed. You can check this in two locations within the edge gateway's settings:

    • Routing > Route Advertisement: The conflicting subnet should no longer appear under Advertised Subnet.

    • Routing > Static Routes: The Route Advertised column for the static route should now show a value of Inactive.

  7. With the advertisement disabled, perform the action that was previously blocked (e.g., change the provider gateway for the edge, or modify the IP Space ranges).

  8. Return to the NSX-T UI.

  9. Re-enable the route advertisement settings that you disabled in step 3.

  10. Return to the Cloud Director UI and refresh the edge gateway page.

  11. Verify that route advertisement for the network is visible again in Cloud Director and that the IP Space status returns to "Normal".
