Quagga

Following on from my previous post on building a FRR package series, this provides the process for installing an FRR (Free Range Routing) package. Some content is taken from Building_FRR_on_Debian8.md.

# update/upgrade existing packages
sudo apt update
sudo apt upgrade

# install a few necessary packages
sudo apt install iproute libc-ares2  libjson-c3

# install frr (users and groups installed via the package)
sudo dpkg -i frr_3.1-dev_amd64.deb

# 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 routing by setting the following in /etc/sysctl.conf, then running 'sysctl -p'

net.ipv4.ip_forward=1
net.ipv6.conf.all.forwarding=1

Configuration files can then be edited as appropriate, then the services started with:

sudo systemctl start frr

Basic instructions for building Debian packages for FRR (Free Range Routing), a fork of Quagga, can be found in the github repository as Building your own FRRouting Debian Package.

These build notes have a slight twist -- using a kernel from backports. It actually doesn't affect the build, but here is my sequence.

sudo apt install -t stretch-backports linux-image-4.14.0-0.bpo.3-amd64 iproute2
sudo reboot
sudo apt --no-install-recommends install \
  libjson-c-dev \
  libpython-dev \
  libsystemd-dev \
  linuxdoc-tools \
  autoconf automake \
  libtool \
  make \
  gawk \
  libreadline-dev \
  texinfo \
  pkg-config \
  bison flex \
  python-pip \
  libc-ares-dev \
  python3-dev \
  devscripts equivs \
  git
git clone https://github.com/frrouting/frr.git frr
cd frr
./bootstrap.sh
./configure --with-pkg-extra-version=-qvsl-1.0
make dist
make dist
export WANT_CUMULUS_MODE=1
mv debianpkg debian
make -f debian/rules backports
mkdir frrpkg
cd frrpkg/
tar xf ~/frr/frr_*.orig.tar.gz
cd frr*
. /etc/os-release
tar xf ~/frr/frr_*${ID}${VERSION_ID}*.debian.tar.xz
sudo mk-build-deps --install debian/control
debuild -b -uc -us

As of this writing, the following packages are built, with the first being the one of interest:

frrpkg/frr_4.1-dev-rpb-1.0-1~debian9+1_amd64.deb
frrpkg/frr-pythontools_4.1-dev-rpb-1.0-1~debian9+1_all.deb
frrpkg/frr-dbg_4.1-dev-rpb-1.0-1~debian9+1_amd64.deb
frrpkg/frr-doc_4.1-dev-rpb-1.0-1~debian9+1_all.deb

gcc -v for debian/stretch yields:

gcc version 6.3.0 20170516 (Debian 6.3.0-18)

2017/11/17: a build note, BGP RPKI available in FRouting

To use this code, ensure that you have installed a new dependant
library rtrlib available here:

http://rtrlib.realmv6.org/

And configure FRR with `--enable-rpki` when compiling it.

2018/04/16 groff, groff-base packages - I am keeping this as a note here because with a minimal list of packages during a build, I may be missing one of these. Next time I perform a build, I'll try to remember to come back here and see what I missed.

Even though it hasn't hit a 1.0 release yet, it sounds as though Quagga, the open source "advanced routing software package that provides a suite of TCP/IP based routing protocols", has become a mature package for use in various parts of a network design. I am looking to use it in several different scenarios: Continue reading "Quagga Installation And Configuration Notes" »
