Debian 8 ======================================== Debian 8 restrictions: ---------------------- - MPLS is not supported on ``Debian 8`` with default kernel. MPLS requires Linux Kernel 4.5 or higher (LDP can be built, but may have limited use without MPLS) Install required packages ------------------------- Add packages: :: sudo apt-get install git autoconf automake libtool make \ libreadline-dev texinfo libjson-c-dev pkg-config bison flex python3-pip \ libc-ares-dev python3-dev python3-sphinx build-essential \ libsnmp-dev libcap-dev libelf-dev Install newer pytest (>3.0) from pip :: sudo pip3 install pytest .. 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 addgroup --system --gid 92 frr sudo addgroup --system --gid 85 frrvty sudo adduser --system --ingroup frr --home /var/run/frr/ \ --gecos "FRR suite" --shell /bin/false 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 \ --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 \ --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 IP & 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 **Reboot** or use ``sysctl -p`` to apply the same config to the running system Troubleshooting ^^^^^^^^^^^^^^^ **Local state directory** The local state directory must exist and have the correct permissions applied for the frrouting daemons to start. In the above ./configure example the local state directory is set to /var/run/frr (--localstatedir=/var/run/frr) Debian considers /var/run/frr to be temporary and this is removed after a reboot. When using a different local state directory you need to create the new directory and change the ownership to the frr user, for example: :: mkdir /var/opt/frr chown frr /var/opt/frr **Shared library error** If you try and start any of the frrouting daemons you may see the below error due to the frrouting shared library directory not being found: :: ./zebra: error while loading shared libraries: libfrr.so.0: cannot open shared object file: No such file or directory The fix is to add the following line to /etc/ld.so.conf which will continue to reference the library directory after the system reboots. To load the library directory path immediately run the ldconfig command after adding the line to the file eg: :: echo include /usr/local/lib >> /etc/ld.so.conf ldconfig
