NAME
       systemd-networkd.service, systemd-networkd - Network manager

SYNOPSIS
       systemd-networkd.service

       /lib/systemd/systemd-networkd

DESCRIPTION
       systemd-networkd is a system service that manages networks. It detects
       and configures network devices as they appear, as well as creating
       virtual network devices.

       To configure low-level link settings independently of networks, see
       systemd.link(5).

       systemd-networkd will create network devices based on the configuration
       in systemd.netdev(5) files, respecting the [Match] sections in those
       files.

       systemd-networkd will manage network addresses and routes for any link
       for which it finds a .network file with an appropriate [Match] section,
       see systemd.network(5). For those links, it will flush existing network
       addresses and routes when bringing up the device. Any links not matched
       by one of the .network files will be ignored. It is also possible to
       explicitly tell systemd-networkd to ignore a link by using
       Unmanaged=yes option, see systemd.network(5).

       When systemd-networkd exits, it generally leaves existing network
       devices and configuration intact. This makes it possible to transition
       from the initramfs and to restart the service without breaking
       connectivity. This also means that when configuration is updated and
       systemd-networkd is restarted, netdev interfaces for which
       configuration was removed will not be dropped, and may need to be
       cleaned up manually.

       systemd-networkd may be introspected and controlled at runtime using
       networkctl(1).

CONFIGURATION FILES
       The configuration files are read from the files located in the system
       network directory /lib/systemd/network, the volatile runtime network
       directory /run/systemd/network and the local administration network
       directory /etc/systemd/network.

       Networks are configured in .network files, see systemd.network(5), and
       virtual network devices are configured in .netdev files, see
       systemd.netdev(5).
