What prerequisite must an administrator complete in VCF before configuring Provider Networking in VCF Automation?

The VCF Automation Provider Networking Guide states:

“Before you can configure Provider Networking, an active Tier-0 (T0) Gateway must be created in NSX Manager and associated with the Provider region.”

This gateway provides external routing and forms the foundation for VPC and tenant networking. Creating a T0 at the Organization level (A) is not correct—organizations consume Provider networking but do not create T0s. vDS in Provider Management (C) or vCenter (D) is unrelated to NSX-based provider networking.

Thus, the required prerequisite is: Create a T0 Gateway in NSX Manager.
