+FreeBSD 10
+==========================================
+
+FreeBSD 10 restrictions:
+------------------------
+
+-  MPLS is not supported on ``FreeBSD``. MPLS requires a Linux Kernel
+   (4.5 or higher). LDP can be built, but may have limited use without
+   MPLS
+
+Install required packages
+-------------------------
+
+Add packages: (Allow the install of the package management tool if this
+is first package install and asked)
+
+::
+
+    pkg install git autoconf automake libtool gmake json-c pkgconf \
+        bison flex py36-pytest c-ares python3.6 py36-sphinx libunwind
+
+.. include:: building-libunwind-note.rst
+
+Make sure there is no /usr/bin/flex preinstalled (and use the newly
+installed in /usr/local/bin): (FreeBSD frequently provides a older flex
+as part of the base OS which takes preference in path)
+
+.. include:: building-libyang.rst
+
+::
+
+    rm -f /usr/bin/flex
+
+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 group and user
+^^^^^^^^^^^^^^^^^^^^^^
+
+::
+
+    pw groupadd frr -g 101
+    pw groupadd frrvty -g 102
+    pw adduser frr -g 101 -u 101 -G 102 -c "FRR suite" \
+        -d /usr/local/etc/frr -s /usr/sbin/nologin
+
+(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
+    export MAKE=gmake
+    export LDFLAGS="-L/usr/local/lib"
+    export CPPFLAGS="-I/usr/local/include"
+    ./configure \
+        --sysconfdir=/usr/local/etc/frr \
+        --enable-pkgsrcrcdir=/usr/pkg/share/examples/rc.d \
+        --localstatedir=/var/run/frr \
+        --prefix=/usr/local \
+        --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
+    gmake
+    gmake check
+    sudo gmake install
+
+Create empty FRR configuration files
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+.. code-block:: shell
+
+   sudo mkdir /usr/local/etc/frr
+
+For integrated config file:
+
+.. code-block:: shell
+
+   sudo touch /usr/local/etc/frr/frr.conf
+
+For individual config files:
+
+.. note:: Integrated config is preferred to individual config.
+
+.. code-block:: shell
+
+   sudo touch /usr/local/etc/frr/babeld.conf
+   sudo touch /usr/local/etc/frr/bfdd.conf
+   sudo touch /usr/local/etc/frr/bgpd.conf
+   sudo touch /usr/local/etc/frr/eigrpd.conf
+   sudo touch /usr/local/etc/frr/isisd.conf
+   sudo touch /usr/local/etc/frr/ldpd.conf
+   sudo touch /usr/local/etc/frr/nhrpd.conf
+   sudo touch /usr/local/etc/frr/ospf6d.conf
+   sudo touch /usr/local/etc/frr/ospfd.conf
+   sudo touch /usr/local/etc/frr/pbrd.conf
+   sudo touch /usr/local/etc/frr/pimd.conf
+   sudo touch /usr/local/etc/frr/ripd.conf
+   sudo touch /usr/local/etc/frr/ripngd.conf
+   sudo touch /usr/local/etc/frr/staticd.conf
+   sudo touch /usr/local/etc/frr/zebra.conf
+   sudo chown -R frr:frr /usr/local/etc/frr/
+   sudo touch /usr/local/etc/frr/vtysh.conf
+   sudo chown frr:frrvty /usr/local/etc/frr/vtysh.conf
+   sudo chmod 640 /usr/local/etc/frr/*.conf
+
+Enable IP & IPv6 forwarding
+^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+Add the following lines to the end of ``/etc/sysctl.conf``:
+
+::
+
+   # Routing: We need to forward packets
+   net.inet.ip.forwarding=1
+   net.inet6.ip6.forwarding=1
+
+**Reboot** or use ``sysctl`` to apply the same config to the running system.
