This topic describes how to configure a Network Extension service. You can perform this task for a single path deployment, or for a standalone network extension on an alternate path.

Follow the steps in, “Start the Hybrid Service Virtual Appliance,” and select the Network Extension service. (If you have already installed the Single Path configuration, Network Extension is your only choice).


On the Network Extension Service page, select a virtual distributed switch from the Distributed Switch drop-down menu.

If you are installing a standard Layer 2 Concentrator, you see the "Route stretched networks via Hybrid Cloud Gateway" check box. It is not there for the high throughput L2C.

If you check “Route stretched networks via Hybrid Cloud Gateway,” the installer determines a reasonable placement for the Layer 2 Concentrator (based on the switch) and populates the placement information accordingly.

If you do not check the box, you must manually enter the placement information in the next step.


Set the route for the L2 Concentrator placement. (If you checked “Route stretched networks via Hybrid Cloud Gateway,” the values you provided cannot be edited.)

Network: The deployment network for the Layer 2 Concentrator’s management interface.

Compute: The deployment cluster or host for the Layer 2 Concentrator.

Datastore: Deployment datastore for the Layer 2 Concentrator.

VM/Hostname: This value is optional.


Specify the Network Parameters for the local Layer 2 Concentrator.

If this option is disabled, you use the default parameters provided by the installer.

If the port group you selected in the Hybrid Cloud Gateway page Network drop-down menu is not part of the distributed switch, check “Specify the Network Parameters for the local Layer 2 Concentrator.” Now you can edit the “Extended Configurations” text boxes.

(Optional) Extended Configurations: Set the admin and root passwords for this specific Layer 2 Concentrator.

Click Next.


On the “Ready to complete” page, review the information, and click Finish.

You can use the task console to monitor deployment progress for a service virtual machine.
