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 py36-pytest c-ares \
python3 py36-sphinx libexecinfo protobuf-c
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
FRR depends on the relatively new libyang
library to provide YANG/NETCONF
support. Unfortunately, most distributions do not yet offer a libyang
package from their repositories. Therefore we offer two options to install this
library.
Option 1: Binary Install
The FRR project builds some binary libyang
packages.
RPM packages are at our RPM repository.
DEB packages are available as CI artifacts here.
Warning
libyang
version 2.1.128 or newer is required to build FRR.
Note
The libyang
development packages need to be installed in addition to the
libyang core package in order to build FRR successfully. Make sure to
download and install those from the link above alongside the binary
packages.
Depending on your platform, you may also need to install the PCRE
development package. Typically this is libpcre2-dev
or pcre2-devel
.
Option 2: Source Install
Note
Ensure that the libyang build requirements
are met before continuing. Usually this entails installing cmake
and
libpcre2-dev
or pcre2-devel
.
git clone https://github.com/CESNET/libyang.git
cd libyang
git checkout v2.1.128
mkdir build; cd build
cmake --install-prefix /usr \
-D CMAKE_BUILD_TYPE:String="Release" ..
make
sudo make install
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"

Create empty FRR configuration files
sudo mkdir /usr/local/etc/frr
For integrated config file:
sudo touch /usr/local/etc/frr/frr.conf
For individual config files:
Note
Integrated config is preferred to individual config.
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

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.
