You can create and manage overlay fabrics from the Manage Overlay Fabrics page.
Before you begin, make sure that you have at least one Layer 3 Fabric based data center in Network Director.
To open the Manage Overlay Fabrics page:
The Manage Overlay Fabrics page opens. Table 187 describes the fields that are displayed in the Manage Overlay Fabrics page.
Table 187: Manage Overlay Fabrics Field Descriptions
Field | Description |
|---|---|
Name | Name of the overlay fabric. |
Description | Description for the overlay fabric. |
Autonomous System No. | The autonomous system number given for the overlay fabric. Autonomous system (AS) is a collection of devices that act as a single administrative entity, such as an overlay fabric. Each autonomous system is assigned a unique autonomous system number. In BGP routing, AS numbers are used to uniquely identify a network on the Internet. |
Route Reflector Network Address | IP address of the route reflector device. Route reflector devices have the ability to readvertise routes learned from an internal peer to other internal peers. Therefore, rather than all internal peers of the fabric to be fully meshed with each other, route reflection requires that only the route reflector be fully meshed with all internal peers. The route reflector and all of its internal peers form a cluster. |
Layer 3 Fabrics | The Layer 3 Fabrics that is part of the overlay fabric. |
Deployment State | Deployment status of the overlay fabric. Deployment state can be one of the following:
|
From the Manage Overlay Fabrics page, you can:
You can create an overlay fabric by following the steps given in this section. Alternatively, you can create an overlay fabric inline while you create a tenant.
To create an overlay fabric:
The Create Overlay Fabric window appears.
Note: You must have at least one Layer 3 Fabric available when you create an overlay fabric. To create a Layer 3 Fabric, follow the procedure given in Creating Layer 3 Fabrics.
After you have created or deployed the overlay configuration, you can create a tenant. See Creating and Managing Tenants for the procedure to create a tenant.
To modify an overlay fabric:
Note: You cannot delete a Layer 3 Fabric that has tenants created in the overlay network. You must remove all the tenants from the Overlay Fabric before you can delete the Layer 3 Fabric.
After you have successfully deployed an overlay fabric, you can view the configuration details of the overlay fabric from the View Overlay Fabric Configuration page. Click the Deployed, Partially Deployed, or the Deploy Failed link corresponding to the overlay fabric under the Deployment State column in the Manage Overlay Fabrics page to open this page.
The View Overlay Fabric Configuration page displays configuration details as described in Table 188.
Table 188: View Overlay Fabric Configuration Details
Field | Description |
|---|---|
Overlay Fabric Name | Name of the overlay fabric for which the configuration details are being viewed. |
Description | Description of the overlay fabric. |
Devices | Device list mapped to the overlay fabric. |
Element Name | Name of the instance mapped to the overlay fabric. |
Configurations | Configuration details of the device for the element (for example, Overlay Fabric). |
Status | Deployment status of the overlay fabric. |
Error Message | Error message for a failed deployment. Note: The error message is visible when the user clicks the hyperlink under the status column. |
