openSUSE
========
This document describes installation from source.
These instructions have been tested on openSUSE Tumbleweed in a Raspberry Pi 400.
Installing Dependencies
-----------------------
.. code-block:: console
zypper in git autoconf automake libtool make \
readline-devel texinfo net-snmp-devel groff pkgconfig libjson-c-devel\
pam-devel python3-pytest bison flex c-ares-devel python3-devel\
python3-Sphinx perl patch libcap-devel \
libelf-devel libunwind-devel protobuf-c
.. include:: building-libunwind-note.rst
.. include:: building-libyang.rst
Building & Installing FRR
-------------------------
Add FRR user and groups
^^^^^^^^^^^^^^^^^^^^^^^
.. code-block:: console
sudo groupadd -g 92 frr
sudo groupadd -r -g 85 frrvty
sudo useradd -u 92 -g 92 -M -r -G frrvty -s /sbin/nologin \
-c "FRR FRRouting suite" -d /var/run/frr 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
.. note::
In some platforms like raspberry for performance reasons
some directories are in file systems (/var/run, ...) mounted with tempfs
so will disapear after every reboot.
In frr the /var/run/frr is used to store pid files for every daemon.
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.
Create a new file ``/etc/sysctl.d/90-routing-sysctl.conf`` with the following
content:
::
#
# Enable packet forwarding
#
net.ipv4.conf.all.forwarding=1
net.ipv6.conf.all.forwarding=1
#
# 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
.. note::
MPLS must be invidividually enabled on each interface that requires it. See
the example in the config block above.
Load the modified sysctls on the system:
.. code-block:: console
sudo sysctl -p /etc/sysctl.d/90-routing-sysctl.conf
Create a new file ``/etc/modules-load.d/mpls.conf`` with the following content:
::
# 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
.. note::
The ``firewalld`` service could be enabled. You may run into some
issues with the iptables rules it installs by default. If you wish to just
stop the service and clear `ALL` rules do these commands:
.. code-block:: console
sudo systemctl disable firewalld.service
sudo systemctl stop firewalld.service
sudo iptables -F
Install frr Service
^^^^^^^^^^^^^^^^^^^
.. code-block:: console
sudo install -p -m 644 tools/frr.service /usr/lib/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 ``bgpd=no`` etc. Enable the daemons
as required by changing the value to ``yes``.
Start FRR
^^^^^^^^^
.. code-block:: console
sudo systemctl start frr
Check the starting messages of frr with
.. code-block:: console
journalctl -u frr --follow
