Assign a Role to a Device
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:
For more information on supported hardware platforms, associated node profiles and roles, see Contrail Networking Supported Hardware Platforms and Associated Roles And Node Profiles.
After you have completed the steps provided in the Discover a Device topic, you can assign roles to the devices from the Assign to devices page.
Follow these steps to assign roles to devices:
- Select the device you want to assign a role to by selecting the check box next to the device name.
- Click the Assign icon at the end of the row
to assign roles.
In Contrail Networking Release 1907, you can assign roles only to similar device types at the same time.
To assign roles to similar device types, select the check box next to the device name and then click Assign Role.
The Assign role to devices pop-up is displayed.
- Select a physical role type from the Physical Role list.
- Select a routing bridging role from the Routing Bridging
These are the supported roles: CRB-Access, CRB-Gateway, DC-Gateway, Route-Reflector, ERB-UCAST-Gateway, DCI-Gateway, CRB-MCAST-Gateway, PNF-Servicechain, AR-Replicator, and AR-Client roles.
For more information, see Centrally-Routed Bridging Overlay Design and Implementation.
Starting with Contrail Networking Release 1907, you can assign the AR-Replicator and AR-Client roles to enable assisted replication on the QFX10000 devices in a datacenter. Assisted replication feature optimizes replication of ingress broadcast, unknown unicast, and multicast (BUM) traffic received from the CE interfaces by replicating BUM traffic towards a single EVPN core Replicator PE (a QFX10000 device) rather than sending it to all the PE devices for replication.
