Regions must be connected to each other. Connection types could be point-to-point links, MPLS, VPN Tunnels, etc. This connection will vary by customer and is out of scope for this design.
The region interconnectivity design must support jumbo frames, and ensure that latency is less than 150 ms. For more details on the requirements for region interconnectivity see the Cross-VC NSX Design Guide.

Provide a connection between regions that is capable of routing between each pod. |
When NSX is configured for cross-vCenter to enable universal objects, connectivity between NSX managers, ESXi host VTEPs and NSX controllers to ESXi hosts management interface is required. To support cross-region authentication, the vCenter Server and Platform Services Controller design requires a single vCenter Single Sign-On domain. Portability of management and compute workloads requires connectivity between regions. |
Jumbo frames are required across regions. |
SDDC-VI-SDN-039 |
Ensure that the latency between regions is less than 150 ms. |
A latency below 150 ms is required for the following features.
