1. Scenario Description

A CEN Basic Edition transit router interconnects VPCs, VBRs and CCNs in a region. A VPC border firewall inspects the traffic between them.

Architecture:

CEN (Basic transit router, one per region)
  +-- business VPC 1..N -- diversion ENI each --+--> Cloud_Firewall_VPC (shared)
                                                +-- Cloud_Firewall_Security_Group

Three facts drive everything else, and the API names obscure all of them. Read references/workflow.md section 1 before reasoning about any response.
