Environment

NSX 9.0

Cause

To delete Tier-0 Gateway, objects that references the gateway such as static routes have to be deleted.

According to VCF NSX-T Edge Cluster Deployment Removal Tool, configuration on top of Edge cluster has to be deleted manually.

Any additional services, interfaces or segments created/deployed on top of the Edge cluster deployment should either be deleted or unlinked. 

Resolution

1. On NSX UI, navigate to Networking > Tier-0 Gateways and edit target Tier-0 gateway.
2. In ROUTING section, delete all static routes.
3. CLOSE EDITING to complete.
4. Run remove_edge_cluster.sh again.

Additional Information

When deleting a Tier-1 or Tier-0 it cannot be deleted because of referenced objects
