Ubuntu 16.04LTS
===============================================
- MPLS is not supported on ``Ubuntu 16.04`` with default kernel. MPLS
requires Linux Kernel 4.5 or higher (LDP can be built, but may have
limited use without MPLS) For an updated Ubuntu Kernel, see
http://kernel.ubuntu.com/~kernel-ppa/mainline/
Install required packages
-------------------------
Add packages:
::
apt-get install \
git autoconf automake libtool make gawk libreadline-dev texinfo dejagnu \
pkg-config libpam0g-dev libjson-c-dev bison flex python-pytest \
libc-ares-dev python3-dev libsystemd-dev python-ipaddress \
python3-sphinx install-info
.. include:: building-libyang.rst
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 -r -g 92 frr
sudo groupadd -r -g 85 frrvty
sudo adduser --system --ingroup frr --home /var/run/frr/ \
--gecos "FRR suite" --shell /sbin/nologin frr
sudo usermod -a -G frrvty 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
./bootstrap.sh
./configure \
--prefix=/usr \
--enable-exampledir=/usr/share/doc/frr/examples/ \
--localstatedir=/var/run/frr \
--sbindir=/usr/lib/frr \
--sysconfdir=/etc/frr \
--enable-multipath=64 \
--enable-user=frr \
--enable-group=frr \
--enable-vty-group=frrvty \
--enable-configfile-mask=0640 \
--enable-logfile-mask=0640 \
--enable-fpm \
--enable-systemd=yes \
--with-pkg-git-version \
--with-pkg-extra-version=-MyOwnFRRVersion
make
make check
sudo make install
Create empty FRR configuration files
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
::
sudo install -m 755 -o frr -g frr -d /var/log/frr
sudo install -m 775 -o frr -g frrvty -d /etc/frr
sudo install -m 640 -o frr -g frr /dev/null /etc/frr/zebra.conf
sudo install -m 640 -o frr -g frr /dev/null /etc/frr/bgpd.conf
sudo install -m 640 -o frr -g frr /dev/null /etc/frr/ospfd.conf
sudo install -m 640 -o frr -g frr /dev/null /etc/frr/ospf6d.conf
sudo install -m 640 -o frr -g frr /dev/null /etc/frr/isisd.conf
sudo install -m 640 -o frr -g frr /dev/null /etc/frr/ripd.conf
sudo install -m 640 -o frr -g frr /dev/null /etc/frr/ripngd.conf
sudo install -m 640 -o frr -g frr /dev/null /etc/frr/pimd.conf
sudo install -m 640 -o frr -g frr /dev/null /etc/frr/ldpd.conf
sudo install -m 640 -o frr -g frr /dev/null /etc/frr/nhrpd.conf
sudo install -m 640 -o frr -g frrvty /dev/null /etc/frr/vtysh.conf
Enable IPv4 & IPv6 forwarding
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
Edit ``/etc/sysctl.conf`` and uncomment the following values (ignore the
other settings)
::
# Uncomment the next line to enable packet forwarding for IPv4
net.ipv4.ip_forward=1
# Uncomment the next line to enable packet forwarding for IPv6
# Enabling this option disables Stateless Address Autoconfiguration
# based on Router Advertisements for this host
net.ipv6.conf.all.forwarding=1
Enable MPLS Forwarding (with Linux Kernel >= 4.5)
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
Edit ``/etc/sysctl.conf`` and the following lines. Make sure to add a
line equal to ``net.mpls.conf.eth0.input`` or each interface used with
MPLS
::
# 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
Add MPLS kernel modules
^^^^^^^^^^^^^^^^^^^^^^^
Add the following lines to ``/etc/modules-load.d/modules.conf``:
::
# Load MPLS Kernel Modules
mpls-router
mpls-iptunnel
**Reboot** or use ``sysctl -p`` to apply the same config to the running
system
Install the systemd service (if rebooted from last step, change directory back to frr directory)
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
::
sudo install -m 644 tools/frr.service /etc/systemd/system/frr.service
sudo install -m 644 tools/etc/frr/daemons /etc/frr/daemons
sudo install -m 644 tools/etc/frr/frr.conf /etc/frr/frr.conf
sudo install -m 644 -o frr -g frr tools/etc/frr/vtysh.conf /etc/frr/vtysh.conf
Enable daemons
^^^^^^^^^^^^^^
| Edit ``/etc/frr/daemons`` and change the value from "no" to "yes" for
those daemons you want to start by systemd.
| For example.
::
zebra=yes
bgpd=yes
ospfd=yes
ospf6d=yes
ripd=yes
ripngd=yes
isisd=yes
Enable the systemd service
^^^^^^^^^^^^^^^^^^^^^^^^^^
- systemctl enable frr
Start the systemd service
^^^^^^^^^^^^^^^^^^^^^^^^^
- systemctl start frr
- use ``systemctl status frr`` to check its status.
