After you have completed the steps provided in the Discover a Device topic, you can assign roles to the devices from the Assign the Roles page.

Figure 1: Assign the Roles Page

Contrail Networking uses tags to identify functions that various devices in a DC fabric can provide. Contrail Networking uses the following roles to tag devices:

Physical roles	A physical role determines whether a device can act as a leaf, spine, or physical network function (PNF).
Routing-bridging roles	These roles are specific to a set of capabilities that a device can deliver in a data center fabric with EVPN-VXLAN.

Steps to Assign Roles to Devices

You can assign roles to a device, or assign roles to multiple devices of the same node profile.

Follow these steps to assign a role to a device.
1. From the Assign to devices table, select the device you want to assign a role to by selecting the check box next to the device name.
2. Click the Assign icon at the end of the row to assign roles. See Figure 4.

Follow these steps to assign roles to multiple devices of the same node profile.
1. From the assign to devices table, select the devices you want to assign a role to by selecting the check box next to the device name.
2. Click Assign roles to devices of same node profile as shown in Figure 5.
  Figure 5: Assign Role to Multiple Devices
The Assign role to devices pop-up is displayed.
You can now assign physical roles and routing-bridging roles.
1. Select a physical role from the Physical Role list.
  For example, select spine role.
2. Select a routing-bridging role from the Routing Bridging Roles list.
  For example, select CRB-Gateway role. You can select more than one routing-bridging role.
  
  For more information on supported hardware platforms, associated node profiles and roles, see Contrail Networking Supported Hardware Platforms and Associated Roles And Node Profiles.
3. Click Assign to confirm selection.
Click Autoconfigure to initiate the auto-configuration job.
The Autoconfigure page is displayed.

The Autoconfigure progress bar on the Discovered devices page displays the progress of the auto-configuration job. Once the auto-configuration job is completed, click Next. The Assign Telemetry Profiles page is displayed.
