Building FRR on Fedora 24 from Git Source
=========================================
Install required packages
-------------------------
Add packages:
sudo dnf install git autoconf automake libtool make gawk \
readline-devel texinfo net-snmp-devel groff pkgconfig \
json-c-devel pam-devel perl-XML-LibXML pytest
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 groups and user
sudo groupadd -g 92 frr
sudo groupadd -r -g 85 frrvt
sudo useradd -u 92 -g 92 -M -r -G frrvt -s /sbin/nologin \
-c "FRR FreeRangeRouting suite" -d /var/run/frr frr
### Download Source, configure and compile it
(You may prefer different options on configure statement. These are just
an example.)
You may want to pay special attention to `/usr/lib64` paths and change
them if you are not building on a x86_64 architecture
git clone https://github.com/freerangerouting/frr.git frr
cd frr
git checkout stable/2.0
./bootstrap.sh
./configure \
--sysconfdir=/etc/frr \
--libdir=/usr/lib64/frr \
--libexecdir=/usr/lib64/frr \
--localstatedir=/var/run/frr \
--enable-pimd \
--enable-snmp=agentx \
--enable-multipath=64 \
--enable-ospfclient=yes \
--enable-ospfapi=yes \
--enable-user=frr \
--enable-group=frr \
--enable-vty-group=frrvt \
--enable-rtadv \
--disable-exampledir \
--enable-watchfrr \
--enable-tcp-zebra \
--enable-fpm \
--with-pkg-git-version \
--with-pkg-extra-version=-MyOwnFRRVersion
make
make check
sudo make install
### Create empty FRR configuration files
sudo mkdir /var/log/frr
sudo mkdir /etc/frr
sudo touch /etc/frr/zebra.conf
sudo touch /etc/frr/bgpd.conf
sudo touch /etc/frr/ospfd.conf
sudo touch /etc/frr/ospf6d.conf
sudo touch /etc/frr/isisd.conf
sudo touch /etc/frr/ripd.conf
sudo touch /etc/frr/ripngd.conf
sudo touch /etc/frr/pimd.conf
sudo touch /etc/frr/ldpd.conf
sudo chown -R frr:frr /etc/frr/
sudo touch /etc/frr/vtysh.conf
sudo chown frr:frrvt /etc/frr/vtysh.conf
sudo chmod 640 /etc/frr/*.conf
### Enable IP & IPv6 forwarding (and MPLS)
Create a new file `/etc/sysctl.d/90-routing-sysctl.conf` with the
following content:
(Please make sure to list all interfaces with required MPLS similar
to `net.mpls.conf.eth0.input=1`)
# Sysctl for routing
#
# Routing: We need to forward packets
net.ipv4.conf.all.forwarding=1
net.ipv6.conf.all.forwarding=1
#
# Enable MPLS Label processing on all interfaces
net.mpls.conf.eth0.input=1
net.mpls.conf.eth1.input=1
net.mpls.conf.eth2.input=1
net.mpls.platform_labels=100000
Create a new file `/etc/modules-load.d/mpls.conf` with the following content:
# Load MPLS Kernel Modules
mpls-router
mpls-iptunnel
**Reboot** or use `sysctl` to apply the same config to the running system
### Install Service files
install -p -m 644 redhat/zebra.service /usr/lib/systemd/system/zebra.service
install -p -m 644 redhat/isisd.service /usr/lib/systemd/system/isisd.service
install -p -m 644 redhat/ripd.service /usr/lib/systemd/system/ripd.service
install -p -m 644 redhat/ospfd.service /usr/lib/systemd/system/ospfd.service
install -p -m 644 redhat/bgpd.service /usr/lib/systemd/system/bgpd.service
install -p -m 644 redhat/ospf6d.service /usr/lib/systemd/system/ospf6d.service
install -p -m 644 redhat/ripngd.service /usr/lib/systemd/system/ripngd.service
install -p -m 644 redhat/pimd.service /usr/lib/systemd/system/pimd.service
install -p -m 644 redhat/pimd.service /usr/lib/systemd/system/ldpd.service
install -p -m 644 redhat/frr.sysconfig /etc/sysconfig/frr
install -p -m 644 redhat/frr.logrotate /etc/logrotate.d/frr
### Register the systemd files
systemctl preset zebra.service
systemctl preset ripd.service
systemctl preset ospfd.service
systemctl preset bgpd.service
systemctl preset ospf6d.service
systemctl preset ripngd.service
systemctl preset pimd.service
systemctl preset ldpd.service
### Enable required daemons at startup
Only enable zebra and the daemons which are needed for your setup
systemctl enable zebra
systemctl enable ospfd
systemctl enable bgpd
[...] etc (as needed)
