+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
