Building & Installing FRR
|
|
-------------------------
|
|
|
|
Add FRR user and groups
|
|
^^^^^^^^^^^^^^^^^^^^^^^
|
|
|
|
.. code-block:: console
|
|
|
|
sudo groupadd -r -g 92 frr
|
|
sudo groupadd -r -g 85 frrvty
|
|
sudo adduser --system --ingroup frr --home /var/run/frr/ \
|
|
--gecos "FRR suite" --shell /sbin/nologin frr
|
|
sudo usermod -a -G frrvty frr
|
|
|
|
Compile
|
|
^^^^^^^
|
|
|
|
.. include:: include-compile.rst
|
|
|
|
Install FRR configuration files
|
|
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
|
|
|
|
.. code-block:: console
|
|
|
|
sudo install -m 775 -o frr -g frr -d /var/log/frr
|
|
sudo install -m 775 -o frr -g frrvty -d /etc/frr
|
|
sudo install -m 640 -o frr -g frrvty tools/etc/frr/vtysh.conf /etc/frr/vtysh.conf
|
|
sudo install -m 640 -o frr -g frr tools/etc/frr/frr.conf /etc/frr/frr.conf
|
|
sudo install -m 640 -o frr -g frr tools/etc/frr/daemons.conf /etc/frr/daemons.conf
|
|
sudo install -m 640 -o frr -g frr tools/etc/frr/daemons /etc/frr/daemons
|
|
|
|
Tweak sysctls
|
|
^^^^^^^^^^^^^
|
|
|
|
Some sysctls need to be changed in order to enable IPv4/IPv6 forwarding and
|
|
MPLS (if supported by your platform). If your platform does not support MPLS,
|
|
skip the MPLS related configuration in this section.
|
|
|
|
Edit :file:`/etc/sysctl.conf` and uncomment the following values (ignore the
|
|
other settings):
|
|
|
|
::
|
|
|
|
# Uncomment the next line to enable packet forwarding for IPv4
|
|
net.ipv4.ip_forward=1
|
|
|
|
# Uncomment the next line to enable packet forwarding for IPv6
|
|
# Enabling this option disables Stateless Address Autoconfiguration
|
|
# based on Router Advertisements for this host
|
|
net.ipv6.conf.all.forwarding=1
|
|
|
|
Reboot or use ``sysctl -p`` to apply the same config to the running system.
|
|
|
|
Add MPLS kernel modules
|
|
"""""""""""""""""""""""
|
|
|
|
Ubuntu 18.04 ships with kernel 4.15. MPLS modules are present by default. To
|
|
enable, add the following lines to :file:`/etc/modules-load.d/modules.conf`:
|
|
|
|
::
|
|
|
|
# Load MPLS Kernel Modules
|
|
mpls_router
|
|
mpls_iptunnel
|
|
|
|
|
|
And load the kernel modules on the running system:
|
|
|
|
.. code-block:: console
|
|
|
|
sudo modprobe mpls-router mpls-iptunnel
|
|
|
|
If the above command returns an error, you may need to install the appropriate
|
|
or latest linux-modules-extra-<kernel-version>-generic package. For example
|
|
``apt-get install linux-modules-extra-`uname -r`-generic``
|
|
|
|
Enable MPLS Forwarding
|
|
""""""""""""""""""""""
|
|
|
|
Edit :file:`/etc/sysctl.conf` and the following lines. Make sure to add a line
|
|
equal to :file:`net.mpls.conf.eth0.input` for each interface used with MPLS.
|
|
|
|
::
|
|
|
|
# Enable MPLS Label processing on all interfaces
|
|
net.mpls.conf.eth0.input=1
|
|
net.mpls.conf.eth1.input=1
|
|
net.mpls.conf.eth2.input=1
|
|
net.mpls.platform_labels=100000
|
|
|
|
Install service files
|
|
^^^^^^^^^^^^^^^^^^^^^
|
|
|
|
.. code-block:: console
|
|
|
|
sudo install -m 644 tools/frr.service /etc/systemd/system/frr.service
|
|
sudo systemctl enable frr
|
|
|
|
Enable daemons
|
|
^^^^^^^^^^^^^^
|
|
|
|
Open :file:`/etc/frr/daemons` with your text editor of choice. Look for the
|
|
section with ``watchfrr_enable=...`` and ``zebra=...`` etc. Enable the daemons
|
|
as required by changing the value to ``yes``.
|
|
|
|
Start FRR
|
|
^^^^^^^^^
|
|
|
|
.. code-block:: shell
|
|
|
|
systemctl start frr
|
