Controller node

Configure network interfaces
----------------------------

#. Configure the first interface as the management interface:

   IP address: 10.0.0.11

   Network mask: 255.255.255.0 (or /24)

   Default gateway: 10.0.0.1

#. The provider interface uses a special configuration without an IP
   address assigned to it. Configure the second interface as the provider
   interface:

   Replace ``INTERFACE_NAME`` with the actual interface name. For example,
   *eth1* or *ens224*.

   For Ubuntu:

   * Edit the ``/etc/network/interfaces`` file to contain the following:

     .. path /etc/network/interfaces
     .. code-block:: bash

        # The provider network interface
        auto INTERFACE_NAME
        iface INTERFACE_NAME inet manual
        up ip link set dev $IFACE up
        down ip link set dev $IFACE down

     .. end

   For RHEL or CentOS:

   * Edit the ``/etc/sysconfig/network-scripts/ifcfg-INTERFACE_NAME`` file
     to contain the following:

     Do not change the ``HWADDR`` and ``UUID`` keys.

     .. path /etc/sysconfig/network-scripts/ifcfg-INTERFACE_NAME
     .. code-block:: ini

        DEVICE=INTERFACE_NAME
        TYPE=Ethernet
        ONBOOT="yes"
        BOOTPROTO="none"

     .. end

   For SUSE:

   * Edit the ``/etc/sysconfig/network/ifcfg-INTERFACE_NAME`` file to
     contain the following:

     .. path /etc/sysconfig/network/ifcfg-INTERFACE_NAME
     .. code-block:: ini

        STARTMODE='auto'
        BOOTPROTO='static'

     .. end

#. Reboot the system to activate the changes.
