2.4.3. Configuring Interfaces

The Overcloud requires a set of network interface templates. The director contains a set of Jinja2-based Heat templates, which render based on your network_data file:

NIC directoryDescriptionEnvironment file

single-nic-vlans

Single NIC (nic1) with control plane and VLANs attached to default Open vSwitch bridge.

environments/net-single-nic-with-vlans-v6.j2.yaml

single-nic-linux-bridge-vlans

Single NIC (nic1) with control plane and VLANs attached to default Linux bridge.

environments/net-single-nic-linux-bridge-with-vlans-v6.yaml

bond-with-vlans

Control plane attached to nic1. Default Open vSwitch bridge with bonded NIC configuration (nic2 and nic3) and VLANs attached.

environments/net-bond-with-vlans-v6.yaml

multiple-nics

Control plane attached to nic1. Assigns each sequential NIC to each network defined in the network_data file. By default, this is Storage to nic2, Storage Management to nic3, Internal API to nic4, Tenant to nic5 on the br-tenant bridge, and External to nic6 on the default Open vSwitch bridge.

environments/net-multiple-nics-v6.yaml

For this example, we use the single-nic-vlans template collection.
