Building FRR on FreeBSD 11 from Git Source
==========================================
FreeBSD 11 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
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
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-ospfclient=yes \
--enable-ospfapi=yes \
--enable-multipath=64 \
--enable-user=frr \
--enable-group=frr \
--enable-vty-group=frrvty \
--enable-configfile-mask=0640 \
--enable-logfile-mask=0640 \
--enable-rtadv \
--enable-tcp-zebra \
--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
sudo touch /usr/local/etc/frr/zebra.conf
sudo touch /usr/local/etc/frr/bgpd.conf
sudo touch /usr/local/etc/frr/ospfd.conf
sudo touch /usr/local/etc/frr/ospf6d.conf
sudo touch /usr/local/etc/frr/isisd.conf
sudo touch /usr/local/etc/frr/ripd.conf
sudo touch /usr/local/etc/frr/ripngd.conf
sudo touch /usr/local/etc/frr/pimd.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
