FreeBSD 9
=========================================
FreeBSD 9 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 -y git autoconf automake libtool gmake \
pkgconf texinfo json-c bison flex py27-pytest c-ares \
python3 py-sphinx libexecinfo
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)
::
rm -f /usr/bin/flex
For building with clang (instead of gcc), upgrade clang from 3.4 default
to 3.6 *This is needed to build FreeBSD packages as well - for packages
clang is default* (Clang 3.4 as shipped with FreeBSD 9 crashes during
compile)
::
pkg install clang36
pkg delete clang34
mv /usr/bin/clang /usr/bin/clang34
ln -s /usr/local/bin/clang36 /usr/bin/clang
.. 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
^^^^^^^^^^^^^^^^^^^^^^
::
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.
