Arch Linux
================
Installing Dependencies
-----------------------
.. code-block:: console
sudo pacman -Syu
sudo pacman -S \
git autoconf automake libtool make cmake pcre readline texinfo \
pkg-config pam json-c bison flex python-pytest \
c-ares python python2-ipaddress python-sphinx \
net-snmp perl libcap libelf libunwind
.. include:: building-libunwind-note.rst
.. include:: building-libyang.rst
Protobuf
^^^^^^^^
.. code-block:: console
sudo pacman -S protobuf-c
ZeroMQ
^^^^^^
.. code-block:: console
sudo pacman -S zeromq
Building & Installing FRR
-------------------------
Add FRR user and groups
^^^^^^^^^^^^^^^^^^^^^^^
.. code-block:: console
sudo groupadd -r -g 92 frr
sudo groupadd -r -g 85 frrvty
sudo useradd --system -g frr --home-dir /var/run/frr/ \
-c "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` [*Create the file if it doesn't exist*] and
append the following values (ignore the other settings):
::
# Enable packet forwarding for IPv4
net.ipv4.ip_forward=1
# Enable packet forwarding for IPv6
net.ipv6.conf.all.forwarding=1
Reboot or use ``sysctl -p`` to apply the same config to the running system.
Add MPLS kernel modules
"""""""""""""""""""""""
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
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
Start FRR
^^^^^^^^^
.. code-block:: shell
systemctl start frr
