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

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.

FRR North bound API
by anzal 14 Jan '19

Hi @Renato Westphal "https://github.com/opensourcerouting/frr/wiki/Architecture " Can this not be used to manage, configure and get updates from the FRR routing daemons by an external NETCONF device, say an SDN controller ? Like ODL has a south bound Netconf - https://docs.opendaylight.org/en/stable-oxygen/user-guide/netconf-user-guid… So by using this I think ODL would be able to configure and get prefix updates from the signalling daemons in FRR. Correct me if I am wrong here. Thanks

Moving on...
by Christian Franke 26 Dec '18

Hi, I would like to announce that I am leaving NetDEF at the end of this year and won't be working on FRR as part of my new job from thereon. I have thoroughly enjoyed the time I have been working with you all, and the decision to leave has not been an easy one for me. However, I would like to shift gears and get a new perspective after having worked on the same codebase for over 6 years. I will try to stay available on the usual channels to answer questions or fix issues in areas I am familar in, however I will do so in my spare time. Thank you all for the great time, All the best, Chris

notes from 12/18 dev meeting
by Mark Stapp 18 Dec '18

18 Dec '18

I've been asked to make some notes about the weekly FRR meetings, so I thought I'd circulate them generally as well. These are ... terse, but if there's something that should be clarified or something that's just plain wrong, please just let me know and I'll correct it. Cheers, Mark * end-of-year review (Donald uses the word "introspection" !) ** DS: effective release schedule, community working together; to-improve: improve test infra to catch issues earlier (general murmurs of agreement about this...) ** Alastair: +community, comm. interest ** DL: need more publicity: about features, traction, viable alternative ** DSlice: conference participation to raise profile too? (beyond ietf and netdev) * publicity/CFP reminder for next netdev, before Prague ietf * issues review ** DS: unowned/poorly-supported features (dmvpn is the example) a problem; we get questions, but then it's hard to help with questions/issues. any ideas about how to fill in these sorts of gaps? * PR review ** isis northbound: Russ agrees with Christian about coupling isisd and fabricd config changes, so wants to revisit the topic, maybe? Renato says, let's take the PR and make progress. DS: I'll just merge it? DL: doesn't like the half-way, inconsistent situation if merged without fabricd changes. Renato: maybe could help re-unify with fabricd in near future. topic *will* come up again if we don't get fabricd done, so merging isisd now, but will need to pay attention to fabricd. ** debian package and working branch for 6.0.1 update: settling, DL wants to release 6.0.1, then do incremental packaging work on the (new) dedicated debian release branch. DL will forward-port to master once it passes muster with the deb folks. ** DS PR to try to begin intro of support for topotests on *bsd, by improving infrastructure. Some other discussion about making topotests more particular about what is tested, so that an unexpected skipped test will be reported. * no meetings on 12/15, 1/1 - so Happy Hols to all...
