Problems installing FRR v7.1-1 on Debian ARM arches
by Quentin Armitage 31 Aug '19

31 Aug '19

apt install frr frr-pythonutils is failing on ARM architectures. When attempting to install just frr from deb.frrouting.org it attempts to install version 7.0.1-1, and not version 7.1-1, but frr-pythonutils is version 7.1-1. The reason for the problem is that https://deb.frrouting.org/frr/dists/buster/frr-stable/binary-armhf/Packages has the old version for some packages and the new version for other packages (e.g. frr-pythonutils). The problem appears to be the same for both armhf and arm64 on all distro versions, but amd64 and i386 do not appear to have the problem. Quentin Armitage

FRR on NRL CORE (fyi)
by Phil Wiggins 22 Aug '19

If anyone is interested in running FRR in the NRL CORE emulation environment, I have some build scripts for FRR on CORE that I posted at the first link below. Normally CORE runs Quagga, so this script was a hack to shoehorn FRR as a Quagga replacement. These scripts are not part of CORE yet, so are unsupported. People on this list may want to use CORE for FRR experimentation and testing, so you can customize these scripts to suit your own needs. It's best to run this stuff in a VM with no internet connection (after installation) since CORE runs lots of processes as root - a well-known security issue. https://github.com/coreemu/core/issues/170 ( install_frr_for_core.sh) FRR on NRL CORE build script - assumes Ubuntu 16.04.4 clean installation in a VM or physical host: https://gist.github.com/apwiggins/44f3592a61965783372aea5881ed9f7a (core_misc_frr.py ) used by the install script above to install at ./core/misc/frr.py https://gist.github.com/apwiggins/d610c2794c8c0a12a45bfc093fd2e949 (core_services_frr.py) used by the install script above to install at ./core/services/frr.py https://gist.github.com/apwiggins/747a9a14feff2ce3a3b8760406b825a7 https://www.nrl.navy.mil/itd/ncs/products/core The Common Open Research Emulator (CORE) is a tool for emulating networks on one or more machines. You can connect these emulated networks to live networks. CORE consists of a GUI for drawing topologies of lightweight virtual machines, and Python modules for scripting network emulation.
