= Example: Network interface with a VRF instance node network configuration policy
|
|
|
|
Associate a Virtual Routing and Forwarding (VRF) instance with a network interface by applying a `NodeNetworkConfigurationPolicy` custom resource (CR).
|
|
|
|
:FeatureName: Associating a VRF instance with a network interface
|
|
include::snippets/technology-preview.adoc[]
|
|
|
|
By associating a VRF instance with a network interface, you can support traffic isolation, independent routing decisions, and the logical separation of network resources.
|
|
|
|
In a bare-metal environment, you can announce load balancer services through interfaces belonging to a VRF instance by using MetalLB. For more information, see the _Additional resources_ section.
|
|
|
|
The following YAML file is an example of associating a VRF instance to a network interface.
|
|
It includes samples values that you must replace with your own information.
