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 managment tool if this is first package install and asked)

pkg install git autoconf automake libtool gmake gawk json-c pkgconf \
    bison flex py27-pytest c-ares python3 py-sphinx

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)

The libyang library can be installed from third-party packages available here.

Note: the libyang dev/devel packages need to be installed in addition to the libyang core package in order to build FRR successfully.

For example, for CentOS 7.x:

wget https://ci1.netdef.org/artifact/LIBYANG-YANGRELEASE/shared/build-1/CentOS-7-x86_64-Packages/libyang-0.16.46-0.x86_64.rpm
wget https://ci1.netdef.org/artifact/LIBYANG-YANGRELEASE/shared/build-1/CentOS-7-x86_64-Packages/libyang-devel-0.16.46-0.x86_64.rpm
sudo rpm -i libyang-0.16.46-0.x86_64.rpm libyang-devel-0.16.46-0.x86_64.rpm

or Ubuntu 18.04:

wget https://ci1.netdef.org/artifact/LIBYANG-YANGRELEASE/shared/build-1/Ubuntu-18.04-x86_64-Packages/libyang-dev_0.16.46_amd64.deb
wget https://ci1.netdef.org/artifact/LIBYANG-YANGRELEASE/shared/build-1/Ubuntu-18.04-x86_64-Packages/libyang_0.16.46_amd64.deb
sudo apt install libpcre3-dev
sudo dpkg -i libyang-dev_0.16.46_amd64.deb libyang_0.16.46_amd64.deb

Alternatively, libyang can be built and installed manually by following the steps below:

git clone https://github.com/opensourcerouting/libyang
cd libyang
git checkout -b tmp origin/tmp
mkdir build; cd build
cmake -DENABLE_LYD_PRIV=ON ..
make
sudo make install

When building libyang on CentOS 6, it’s also necessary to pass the -DENABLE_CACHE=OFF parameter to cmake.

Note: please check the libyang build requirements first.

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

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
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.
