Building FRR on OpenBSD 6 from Git Source
=========================================
Install required packages
-------------------------
Configure PKG_PATH
export PKG_PATH=http://ftp5.usa.openbsd.org/pub/OpenBSD/$(uname -r)/packages/$(machine -a)/
Add packages:
pkg_add git autoconf-2.69p2 automake-1.15p0 libtool bison
pkg_add gmake gawk dejagnu openssl json-c py-test
Select Python2.7 as default (required for pytest)
ln -s /usr/local/bin/python2.7 /usr/local/bin/python
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
groupadd -g 525 _frr
groupadd -g 526 _frrvty
useradd -g 525 -u 525 -c "FRR suite" -G _frrvty \
-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 https://github.com/frrouting/frr.git frr
cd frr
export AUTOCONF_VERSION="2.69"
export AUTOMAKE_VERSION="1.15"
./bootstrap.sh
export LDFLAGS="-L/usr/local/lib"
export CPPFLAGS="-I/usr/local/include"
./configure \
--sysconfdir=/etc/frr \
--localstatedir=/var/frr \
--enable-pimd \
--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-fpm \
--with-pkg-git-version \
--with-pkg-extra-version=-MyOwnFRRVersion
gmake
gmake check
doas gmake install
### Create empty FRR configuration files
doas mkdir /var/frr
doas chown _frr:_frr /var/frr
doas chmod 755 /var/frr
doas mkdir /etc/frr
doas touch /etc/frr/zebra.conf
doas touch /etc/frr/bgpd.conf
doas touch /etc/frr/ospfd.conf
doas touch /etc/frr/ospf6d.conf
doas touch /etc/frr/isisd.conf
doas touch /etc/frr/ripd.conf
doas touch /etc/frr/ripngd.conf
doas touch /etc/frr/pimd.conf
doas touch /etc/frr/ldpd.conf
doas touch /etc/frr/nhrpd.conf
doas chown -R _frr:_frr /etc/frr
doas touch /etc/frr/vtysh.conf
doas chown -R _frr:_frrvty /etc/frr/vtysh.conf
doas chmod 750 /etc/frr
doas chmod 640 /etc/frr/*.conf
### Enable IP & IPv6 forwarding
Add the following lines to the end of `/etc/rc.conf`:
net.inet6.ip6.forwarding=1 # 1=Permit forwarding of IPv6 packets
net.inet6.ip6.mforwarding=1 # 1=Permit forwarding of IPv6 multicast packets
net.inet6.ip6.multipath=1 # 1=Enable IPv6 multipath routing
**Reboot** to apply the config to the system
### Enable MPLS Forwarding
To enable MPLS forwarding on a given interface, use the following command:
doas ifconfig em0 mpls
Alternatively, to make MPLS forwarding persistent across reboots, add the "mpls"
keyword in the hostname.* files of the desired interfaces. Example:
cat /etc/hostname.em0
inet 10.0.1.1 255.255.255.0 mpls
### Install rc.d init files
(create them in /etc/rc.d - no example are included at this time with
FRR source)
Example (for zebra - store as `/etc/rc.d/frr_zebra.sh`)
#!/bin/sh
#
# $OpenBSD: frr_zebra.rc,v 1.1 2013/04/18 20:29:08 sthen Exp $
daemon="/usr/local/sbin/zebra -d"
. /etc/rc.d/rc.subr
rc_cmd $1
### Enable FRR processes
(Enable the required processes only)
echo "frr_zebra=YES" >> /etc/rc.conf
echo "frr_bgpd=YES" >> /etc/rc.conf
echo "frr_ospfd=YES" >> /etc/rc.conf
echo "frr_ospf6d=YES" >> /etc/rc.conf
echo "frr_isisd=YES" >> /etc/rc.conf
echo "frr_ripngd=YES" >> /etc/rc.conf
echo "frr_ripd=YES" >> /etc/rc.conf
echo "frr_pimd=YES" >> /etc/rc.conf
echo "frr_ldpd=YES" >> /etc/rc.conf
