To onboard Fabrics into an MSD Fabric, you will add your existing fabrics as child fabrics to the parent MSD fabric. Tenant overlay VRFs (L3VNIs) and Networks (L2VNIs) will then be created from the MSD fabric going forward.

To begin adding your fabrics into your MSD fabric, you need to launch the Select Child Fabrics popup. To do this:

1. Click the Child Fabrics tab in the top navigation bar
2. Click Actions
3. Then, click Move Fabric into MSD in the dropdown menu

Step 2 - Add Site1 Fabric

The first fabric you want to select and import is your Site1 fabric. Locate Site1 in the list of fabrics.

1. Click Site1
2. Click Select

3. Click Ok in the warning popup that informs that you must perform a Recalulate and Deploy.

Step 3 - Launch Add Child Fabrics Again

Launch the Select Child Fabrics popup again. To do this:

The second fabric you want to select and import is your Site2 fabric. Locate Site2 in the list of fabrics and notice the fabric list has shorted since Site1 was previously selected.

1. Click Site2
2. Click Select

3. Click Ok in the warning popup that informs that you must perform a Recalulate and Deploy.

Step 5 - Launch Add Child Fabrics One More Time

Launch the Select Child Fabrics popup one last time. To do this:

Step 8 - Revisit Overview Dashboard for MSD

In your updated MSD Overview dashboard, note that you have three (3) fabrics with a total count of switches across all fabrics with health, configuration, roles, and hardware versions as alluded to earlier. Followed by the switch details, the VXLAN information is a total of all fabrics: Underlay routing loopbacks, VTEP loopbacks and corresponding NVE interface statuses, and total L2VNIs (Networks) and L3VNIs (VRFs). The Multisite Loopbacks will populate a status once the multisite configuration is deployed onto the border gateway leaf switches.
