NetBSD 6

NetBSD 6 restrictions:

  • MPLS is not supported on NetBSD. MPLS requires a Linux Kernel (4.5 or higher). LDP can be built, but may have limited use without MPLS

Install required packages

Configure Package location:

PKG_PATH="`uname -m`/`uname -r`/All"
export PKG_PATH

Add packages:

sudo pkg_add git autoconf automake libtool gmake openssl \
   pkg-config json-c py36-test python36 py36-sphinx \

Install SSL Root Certificates (for git https access):

sudo pkg_add mozilla-rootcerts
sudo touch /etc/openssl/openssl.cnf
sudo mozilla-rootcerts install

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.


libyang version 2.1.128 or newer is required to build FRR.


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


Ensure that the libyang build requirements are met before continuing. Usually this entails installing cmake and libpcre2-dev or pcre2-devel.

git clone
cd libyang
git checkout v2.1.128
mkdir build; cd build
cmake --install-prefix /usr \
      -D CMAKE_BUILD_TYPE:String="Release" ..
sudo make install

Get FRR, compile it and install it (from Git)

Add frr groups and user

sudo groupadd -g 92 frr
sudo groupadd -g 93 frrvty
sudo useradd -g 92 -u 92 -G frrvty -c "FRR suite" \
    -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)

git clone frr
cd frr
export LDFLAGS="-L/usr/pkg/lib -R/usr/pkg/lib"
export CPPFLAGS="-I/usr/pkg/include"
./configure \
    --sysconfdir=/usr/pkg/etc \
    --localstatedir=/var \
    --enable-pkgsrcrcdir=/usr/pkg/share/examples/rc.d \
    --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 \
gmake check
sudo gmake install

Create empty FRR configuration files

sudo mkdir /var/log/frr
sudo mkdir /usr/pkg/etc/frr
sudo touch /usr/pkg/etc/frr/zebra.conf
sudo touch /usr/pkg/etc/frr/bgpd.conf
sudo touch /usr/pkg/etc/frr/ospfd.conf
sudo touch /usr/pkg/etc/frr/ospf6d.conf
sudo touch /usr/pkg/etc/frr/isisd.conf
sudo touch /usr/pkg/etc/frr/ripd.conf
sudo touch /usr/pkg/etc/frr/ripngd.conf
sudo touch /usr/pkg/etc/frr/pimd.conf
sudo chown -R frr:frr /usr/pkg/etc/frr
sudo touch /usr/local/etc/frr/vtysh.conf
sudo chown frr:frrvty /usr/pkg/etc/frr/*.conf
sudo chmod 640 /usr/pkg/etc/frr/*.conf

Enable IP & IPv6 forwarding

Add the following lines to the end of /etc/sysctl.conf:

# Routing: We need to forward packets

Reboot or use sysctl to apply the same config to the running system

Install rc.d init files

cp pkgsrc/*.sh /etc/rc.d/
chmod 555 /etc/rc.d/*.sh

Enable FRR processes

(Enable the required processes only)
