You can configure VMware HCX to use VMware Transit Connect™ for migration and network extension traffic.

VMware Transit Connect connects your SDDCs and VPCs to provide high-bandwidth, low-latency connections between SDDCs in the group and to other VPCs in the same region. The Direct Connect network profile is used for Transit Connect. For instructions on how to configure Direct Connect, refer to the section Configuring VMware HCX for Direct Connect Private Virtual Interfaces.
