Hi, Sangfor HCI handles overlay network communication for virtual machines (VMs) as it follows:

Overlay Network Interfaces:
In Sangfor HCI, overlay network interfaces play a crucial role in facilitating communication between nodes within the HCI cluster.
These interfaces allow VMs running on different nodes to communicate seamlessly.

Communication Flow:
When two VMs are connected to the same virtual switch:
If the virtual switch is not isolated from the edge, packets physically exit from the edge, traverse the physical network, and return to the edge before reaching the other VM.
However, if the virtual switch is isolated from the edge, packets only pass through the virtual switch and use the overlay network to reach resources on other nodes.
The latter approach is more efficient, as traffic into the virtual switch primarily utilizes the overlay network and accesses the physical network only when necessary.

Edge-Connected Interface:
Sangfor HCI clusters use an edge-connected interface to communicate with the physical network.
VMs are accessed from external networks through this interface.
