Install FRR configuration files
|
||||
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
|
||||
|
||||
Create empty FRR configuration files
|
||||
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
|
||||
.. code-block:: console
|
||||
|
||||
Although not strictly necessary, it's good practice to create empty
|
||||
configuration files _before_ starting FRR. This assures that the permissions
|
||||
are correct. If the files are not already present, FRR will create them.
|
||||
|
||||
It's also important to consider _which_ files to create. FRR supports writing
|
||||
configuration to a monolithic file, :file:`/etc/frr/frr.conf`.
|
||||
|
||||
.. seealso:: *VTYSH* section of user guide
|
||||
|
||||
The presence of :file:`/etc/frr/frr.conf` on startup implicitly configures FRR
|
||||
to ignore daemon-specific configuration files.

skip the MPLS related configuration in this section.

Edit ``/etc/frr/daemons`` and change the value from "no" to "yes" for those
|

daemons you want to start by systemd. For example:
|

Open :file:`/etc/frr/daemons` with your text editor of choice. Look for the

Enabling the systemd service causes FRR to be started upon boot. To enable it,
|
||||
use the following command:
|
||||
|
||||
.. code-block:: shell
|
||||
|
||||
systemctl enable frr
|
||||
|
||||
Start the systemd service

Start FRR

^^^^^^^^^
|
||||
|

systemctl start frr
|
||||
|
||||
After starting the service, you can use ``systemctl status frr`` to check its
|
||||
status.
