These are just an example) .. warning:: In openbsd the proper links for the libyang library may not have been created. :: ln -s /usr/lib/libyang.so.1.10.17 /usr/lib/libyang.so .. warning:: ``openbsd`` since version 6.2 has ``clang`` as the default compiler so to build frr, clang must be used (the included gcc version is very old). :: 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 \ --localstatedir=/var \ --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 \ CC=clang 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
