Environment

• VMware Cloud Director 10.6.x
• VMware Cloud Director 10.5.x
• VMware Avi Load Balancer

Cause

This issue occurs if the VRF Context name in Avi Load Balancer is not correct for the Edge Gateway being modified in Cloud Director.

For example if the Edge Gateway is renamed in the Cloud Director UI, then this name change may not be propagated down to the VRF Context in Avi Load Balancer.

Resolution

To resolve the issue, ensure that the name of the VRF Context in Avi Load Balancer associated with the Cloud Director Edge is in the correct format.
The name of the VRF Context must take the from <EDGE_NAME>-<EDGE_ID>.

Workaround:

1. Log into the Cloud Director Provider Portal as a System Administrator.
2. Click on the affected Edge Gateway in Resources > Cloud Resources > Edge Gateways > Edge Name.
3. Note the name on of the Edge as displayed in the Cloud Director UI under Configuration > General > Name.
   For example:
   
   Edge Name
   ExampleEdge
4. Note the ID of the Edge as displayed in the URL of the browser after opening the Edge.
   For example:
   
   URL
   https:///provider/cloud/edge-gateways/cloud/urn:vcloud:gateway:1234abcd-####-####-####-############/config/general
   
   Edge ID
   1234abcd-####-####-####-############
   
   
5. Using the Edge Name and Edge ID create the expected VRF Context name in the from <EDGE_NAME>-<EDGE_ID>.
   For example:
   
   VRF Context Name
   ExampleEdge-1234abcd-####-####-####-############
   
   
6. Log into the Avi Load Balancer UI as an administrator.
7. Open Infrastructure > Cloud Resources > VRF Context and under the Select Cloud dropdown select the Avi Cloud that is used with Cloud Director and the Edge Gateway in question.
8. Search for the Edge ID of the affected Edge Gateway by clicking the search icon.
   For example:
   
   1234abcd-####-####-####-############
   
   
9. Confirm that the Edge Name portion of the VRF Context name does NOT match the Edge Name in the Cloud Director UI.
10. If the name is incorrect Edit the VRF Context and change the General > Name field to match the format expected by Cloud Director as constructed in step 5. above.
    For example:
    
    VRF Context Name
    ExampleEdge-1234abcd-####-####-####-############
    
    
11. Save the name change and retry enabling Transparent Mode on the Edge Gateway in the Cloud Director UI.
