Debian 8
========================================
Debian 8 restrictions:
----------------------
- MPLS is not supported on ``Debian 8`` with default kernel. MPLS
requires Linux Kernel 4.5 or higher (LDP can be built, but may have
limited use without MPLS)
Install required packages
-------------------------
Add packages:
::
sudo apt-get install git autoconf automake libtool make \
libreadline-dev texinfo libjson-c-dev pkg-config bison flex python3-pip \
libc-ares-dev python3-dev python3-sphinx build-essential \
libsnmp-dev libcap-dev libelf-dev
Install newer pytest (>3.0) from pip
::
sudo pip3 install pytest
.. include:: building-libyang.rst
Get FRR, compile it and install it (from Git)
---------------------------------------------
**This assumes you want to build and install FRR from source and not
using any packages**
Add frr groups and user
^^^^^^^^^^^^^^^^^^^^^^^
::
sudo addgroup --system --gid 92 frr
sudo addgroup --system --gid 85 frrvty
sudo adduser --system --ingroup frr --home /var/run/frr/ \
--gecos "FRR suite" --shell /bin/false frr
sudo usermod -a -G frrvty frr
Download Source, configure and compile it
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
(You may prefer different options on configure statement. These are just
an example.)
::
git clone https://github.com/frrouting/frr.git frr
cd frr
./bootstrap.sh
./configure \
--localstatedir=/var/run/frr \
--sbindir=/usr/lib/frr \
--sysconfdir=/etc/frr \
--enable-multipath=64 \
--enable-user=frr \
--enable-group=frr \
--enable-vty-group=frrvty \
--enable-configfile-mask=0640 \
--enable-logfile-mask=0640 \
--enable-fpm \
--with-pkg-git-version \
--with-pkg-extra-version=-MyOwnFRRVersion
make
make check
sudo make install
Create empty FRR configuration files
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
::
sudo install -m 755 -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 frr /dev/null /etc/frr/zebra.conf
sudo install -m 640 -o frr -g frr /dev/null /etc/frr/bgpd.conf
sudo install -m 640 -o frr -g frr /dev/null /etc/frr/ospfd.conf
sudo install -m 640 -o frr -g frr /dev/null /etc/frr/ospf6d.conf
sudo install -m 640 -o frr -g frr /dev/null /etc/frr/isisd.conf
sudo install -m 640 -o frr -g frr /dev/null /etc/frr/ripd.conf
sudo install -m 640 -o frr -g frr /dev/null /etc/frr/ripngd.conf
sudo install -m 640 -o frr -g frr /dev/null /etc/frr/pimd.conf
sudo install -m 640 -o frr -g frr /dev/null /etc/frr/ldpd.conf
sudo install -m 640 -o frr -g frr /dev/null /etc/frr/nhrpd.conf
sudo install -m 640 -o frr -g frrvty /dev/null /etc/frr/vtysh.conf
Enable IP & IPv6 forwarding
^^^^^^^^^^^^^^^^^^^^^^^^^^^
Edit ``/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
Troubleshooting
^^^^^^^^^^^^^^^
**Local state directory**
The local state directory must exist and have the correct permissions
applied for the frrouting daemons to start. In the above ./configure
example the local state directory is set to /var/run/frr
(--localstatedir=/var/run/frr) Debian considers /var/run/frr to be
temporary and this is removed after a reboot.
When using a different local state directory you need to create the new
directory and change the ownership to the frr user, for example:
::
mkdir /var/opt/frr
chown frr /var/opt/frr
**Shared library error**
If you try and start any of the frrouting daemons you may see the below
error due to the frrouting shared library directory not being found:
::
./zebra: error while loading shared libraries: libfrr.so.0: cannot open shared object file: No such file or directory
The fix is to add the following line to /etc/ld.so.conf which will
continue to reference the library directory after the system reboots. To
load the library directory path immediately run the ldconfig command
after adding the line to the file eg:
::
echo include /usr/local/lib >> /etc/ld.so.conf
ldconfig
