+OpenBSD 6
+=========================================
+
+Install required packages
+-------------------------
+
+Configure PKG\_PATH
+
+::
+
+    export PKG_PATH=http://ftp5.usa.openbsd.org/pub/OpenBSD/$(uname -r)/packages/$(machine -a)/
+
+Add packages:
+
+::
+
+    pkg_add clang libcares python3
+    pkg_add git autoconf-2.69p2 automake-1.15.1 libtool bison
+    pkg_add gmake json-c py-test py-sphinx libexecinfo
+
+Select Python2.7 as default (required for pytest)
+
+::
+
+    ln -s /usr/local/bin/python2.7 /usr/local/bin/python
+
+.. 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 group and user
+^^^^^^^^^^^^^^^^^^^^^^
+
+::
+
+    groupadd -g 525 _frr
+    groupadd -g 526 _frrvty
+    useradd -g 525 -u 525 -c "FRR suite" -G _frrvty \
+        -d /nonexistent -s /sbin/nologin _frr
+
+Download Source, configure and compile it
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+(You may prefer different options on configure statement. These are just
+an example)
+
+.. warning::
+
+   In openbsd the proper links for the libyang library may not have been created.
+
+::
+
+    ln -s /usr/lib/libyang.so.1.10.17 /usr/lib/libyang.so
+
+.. warning::
+
+   ``openbsd`` since version 6.2 has ``clang`` as the default compiler so to 
+   build frr, clang must be used (the included gcc version is very old).
+
+::
+
+    git clone https://github.com/frrouting/frr.git frr
+    cd frr
+    export AUTOCONF_VERSION="2.69"
+    export AUTOMAKE_VERSION="1.15"
+    ./bootstrap.sh
+    export LDFLAGS="-L/usr/local/lib"
+    export CPPFLAGS="-I/usr/local/include"
+    ./configure \
+        --sysconfdir=/etc/frr \
+        --localstatedir=/var/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 \
+        CC=clang
+    gmake
+    gmake check
+    doas gmake install
+
+Create empty FRR configuration files
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+::
+
+    doas mkdir /var/frr
+    doas chown _frr:_frr /var/frr
+    doas chmod 755 /var/frr
+    doas mkdir /etc/frr
+    doas touch /etc/frr/zebra.conf
+    doas touch /etc/frr/bgpd.conf
+    doas touch /etc/frr/ospfd.conf
+    doas touch /etc/frr/ospf6d.conf
+    doas touch /etc/frr/isisd.conf
+    doas touch /etc/frr/ripd.conf
+    doas touch /etc/frr/ripngd.conf
+    doas touch /etc/frr/pimd.conf
+    doas touch /etc/frr/ldpd.conf
+    doas touch /etc/frr/nhrpd.conf
+    doas chown -R _frr:_frr /etc/frr
+    doas touch /etc/frr/vtysh.conf
+    doas chown -R _frr:_frrvty /etc/frr/vtysh.conf
+    doas chmod 750 /etc/frr
+    doas chmod 640 /etc/frr/*.conf
+
+Enable IP & IPv6 forwarding
+^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+Add the following lines to the end of ``/etc/rc.conf``:
+
+::
+
+    net.inet6.ip6.forwarding=1      # 1=Permit forwarding of IPv6 packets
+    net.inet6.ip6.mforwarding=1     # 1=Permit forwarding of IPv6 multicast packets
+    net.inet6.ip6.multipath=1       # 1=Enable IPv6 multipath routing
+
+**Reboot** to apply the config to the system
+
+Enable MPLS Forwarding
+^^^^^^^^^^^^^^^^^^^^^^
+
+To enable MPLS forwarding on a given interface, use the following
+command:
+
+::
+
+    doas ifconfig em0 mpls
+
+Alternatively, to make MPLS forwarding persistent across reboots, add
+the "mpls" keyword in the hostname.\* files of the desired interfaces.
+Example:
+
+::
+
+    cat /etc/hostname.em0
+    inet 10.0.1.1 255.255.255.0 mpls
+
+Install rc.d init files
+^^^^^^^^^^^^^^^^^^^^^^^
+
+(create them in /etc/rc.d - no example are included at this time with
+FRR source)
+
+Example (for zebra - store as ``/etc/rc.d/frr_zebra.sh``)
+
+::
+
+    #!/bin/sh
+    #
+    # $OpenBSD: frr_zebra.rc,v 1.1 2013/04/18 20:29:08 sthen Exp $
+
+    daemon="/usr/local/sbin/zebra -d"
+
+    . /etc/rc.d/rc.subr
+
+    rc_cmd $1
+
+Enable FRR processes
+^^^^^^^^^^^^^^^^^^^^
+
+(Enable the required processes only)
+
+::
+
+    echo "frr_zebra=YES" >> /etc/rc.conf
+    echo "frr_bgpd=YES" >> /etc/rc.conf
+    echo "frr_ospfd=YES" >> /etc/rc.conf
+    echo "frr_ospf6d=YES" >> /etc/rc.conf
+    echo "frr_isisd=YES" >> /etc/rc.conf
+    echo "frr_ripngd=YES" >> /etc/rc.conf
+    echo "frr_ripd=YES" >> /etc/rc.conf
+    echo "frr_pimd=YES" >> /etc/rc.conf
+    echo "frr_ldpd=YES" >> /etc/rc.conf
