Provisioning additional networking

Provision additional networking for direct network access to a container or to a virtual machine.

1. Define the network range and the VLAN for which the external network traffic will traverse.
   1. Log in to IBM Fusion HCI System user interface.
   2. Go to Networking page and go to VLAN tab.
   3. Click Add VLAN to define a new VLAN.
   4. Select the VLAN Type as Cloud Satellite VLAN.
   5. Add the newly Defined VLAN to the Uplink ports on the high speed switches.
      In the Edit VLAN slide out panel, select value for VLANs and Save.
2. Log in to OpenShift Container Platform web console.
3. Go to Administration > CustomResourceDefinitions.
4. Search for nodenetworkconfigurationpolicies.nmstate.io and click to open it.
5. In the Instances tab, view the NNCP policy created with the previously created VLAN ID. For example, if the created VLAN ID is "2222", the NNCP policy name is "br2222-bond0-policy".
6. Copy the bridge name. In this example, it is "br2222".
7. Select your project or namespace and go to Networking > NetworkAttachmentDefinitions.
8. In the NetworkAttachmentDefinitions, click Create Network Attachment Definition to create a new Network Attachment Definition specific to the desired namespace.
   You can reuse the same network attachment definitions across multiple namespaces.
9. Check whether the Bridge Name is same as the one created by the node network policy. In this example, it is "br2222".
10. You can now attach a second network adapter to your virtual machine at the time of network configuration, and assign it to the defined network attachment definition. It allows access to the external network.
