# Set OS network configuration

- This configuration uses named interfaces for ease.
- The network topology represents the viable minimum logical networks required to build a multinode(2) cluster (no baremetal provisioning).
- The API and PROVIDER networks are on their own physical interfaces, the TUNNEL and STORAGE networks are VLANs on another physical interface.

```sh
nano -cw /etc/netplan/00-installer-config.yaml

network:
  version: 2
  ethernets:
    api:
      match:
        name: enp0s3
      set-name: api
      addresses: [192.168.30.60/24]
      gateway4: 192.168.30.1
      nameservers:
        addresses: [192.168.140.2, 192.168.140.1]
    servicenet:
      match:
        name: enp0s8
      set-name: servicenet
    provider:
      match:
        name: enp0s9
      set-name: provider
  vlans:
    tunnel:
      id: 31
      link: servicenet
      addresses: [192.168.31.60/24]
    storage:
      id: 32
      link: servicenet
      addresses: [192.168.32.60/24]
```

The `netplan apply` command will not work with this config owing to the range of changes, reboot the node.
