Route map filtering in OSPF
by Akshata Danivasa 31 May '17

31 May '17

Hi, I have a query regarding FRR for route map filtering we have: *distribute-list access-list-name out * Does this mean there is no inbound route filtering? Does distribute-list apply only for access-lists or can also be for route-maps that are configured? Thanks, Akshata

Items for Agenda for next (or soon) weekly call
by Martin Winter 27 May '17

27 May '17

Just a quick note for agenda items on a tuesday call (or do we prefer to discuss on list?) - Process on updating website not current process, but how to do this in future and how to get there and who is doing it - Testcases for new features We are getting a lot of new features in which are not yet covered by any test cases in our CI system. I assume most/all contributors test them on their own before submitting, but should we have some requirement to provide some tests with any/most new features? Could be a hard requirement like additions to unit test or topotest (or any other kind of test) or some soft requirement in a description on how it was tested I don’t see any of these urgent, but would love to have some discussion… - Martin

Package discussion & Init scripts
by Martin Winter 24 May '17

24 May '17

So to start this discussion on the packaging, I would like to base this discussion on 2 decisions which need to be done first: -- 1) Do we want to use 'vtysh integrated-config' for FRR 2.0 packages ? I believe we all agree that this is the way to go in the future. I'm certain we had this discussion before (but can't find pointers in my email). My understanding is that we decided to use per-daemon config for 2.0, but plan to move to integrated configs soon after. The main discussion point was the migration path from classic Quagga (with separate configs) and the lack of the capability for each daemon to read directly from the integrated config (which requires the extra step of vtysh to re-load configs if a daemon restart). There is also the issue for users not running zebra (or does integrated config work for a deployment with only BGP?) I thought we agreed to somehow address these issues before we push users to the integrated config. Anyone remembers this discussion? (Or remembers it different?) -- 2) Do we want the packages on each platform as close to each other as possible or do we want it to follow the conventions of each distro as close as possible? I assume (on the short term), we end up at least with packages for - Debian (Ubuntu 14.04, 16.04, Debian 8) - Redhat (RedHat 6, 7, CentOS 6, 7, Fedora) - FreeBSD - Snap packages I thought about the packages as reference packages for package maintainers to build on (and the merging changes from the back in as far as possible) Each platform has differences in capabilities and guidelines for building them: - Conventions where configs and binaries should be installed - Startup system (init.d, systemd and others) - Configuration location (ie /etc/sysconfig for redhat, /etc/debian for debian etc) Each system also provides functions and examples for startup scripts. After this is decided, then I think we can talk about the issues on exceptions Technical challenges like: - everything runs under root with apparmor (ie Snap's) - Some required packages are not available from standard repo (ie Python 2.7 or ipaddr python module for Redhat 6) -- My preferred short term solution: I would still prefer to get the redhat changes in as they are now for the stable/2.0 branch (and the debian changes as soon as possible as well). We could reopen this discussion later once we actually have working packages for at least these 2 platforms -- I really like to get more opinions here - beside mine and Donald's. Specially if you have experience with packages or you know someone you could ask. - Martin Here is a link to some basic description of an init file for RedHat based systems: http://www.sensi.org/~alec/unix/redhat/sysvinit.html (Original is provided on a redhat system in /usr/share/doc/initscripts-*/sysvinitfiles)
