New in BIRD
by Ilias Pallikarakis 23 Aug '16

Hi, I recently started trying to learn BIRD. I should also mention I have no previous experience with any other Routing daemon either. I want to configure a bgp monitor for both ipv4 and ipv6. I am running BIRD in a Ubuntu 13.10 VM. I managed to install both bird and bird6 but I have some problems with the configurations. In ipv4 : I created a very simple configuration which I attach. The conf is compiled but in birdc the bgp session is considered idle. I tried to do a tcpdump and found that the router sends a TCP SYN on the VM's bgp port but the VM responds with a RST and never tries to set a BGP session itself. In ipv6 : No matter the configuration (my configuration or the sample coming with bird6 or examples found on the web) the configuration is not compiled giving the following error : BIRD ipv6 doesn't run (bird: /usr/local/etc/bird6.conf, line 1: Router ID must be configured manually on IPv6 routers) Could anyone give me some pointers on what I am doing wrong ? Thank you for your help, Ilias Pallikarakis

Release plans?
by Shaun Crampton 27 Apr '16

27 Apr '16

Hi, I was just wondering if the BIRD team had any plans to do a release any time soon (I think that would be 1.6?). We'd really like to have a release with BGP multi-path support. Regards, -Shaun

[PATCH master v2] IPv6 ECMP support fixes for linux
by Mikhail Sennikovskii 04 Apr '16

04 Apr '16

Hi Ondrej and all, Here is the second version of the Linux IPv6 ECMP support patch. It encorporates the adjustments, requested by Ondrej, as well as some other modifications/fixes, accompanied by the comments in the code. To save a bit of my time, I've created just one patch against the master for now. Once we agree on the patch, I will create a patch agains int-new right away, since adapting it to int-new is really strait-forward. Also, as we discussed before, I will also create a separate patch to make the nl_parse_multipath use netlink_lp (linpool) instead of xrealloc, once we agree on the current netlink_lp approach that I've introduced. Regards, Mikhail

Monitoring routes from Nagios
by Michael Ludvig 30 Mar '16

30 Mar '16

Hi What approach do you have for monitoring routing status in your environments? We've got OSPF set up between our sites (offices and data centres) and BGP for uplinks from some sites. I want to monitor by Nagios that everything is as expected. For example: - BGP feeds from ISPs look sane (e.g. include 0.0.0.0/0 - as that's what we are interested in) - configured OSPF peers are all connected - ... what else? I can write some scripts to parse "birdc show ..." output and feed that into Nagios but perhaps someone has a better way to do that? Thanks! Michael

Bird website documentation seems to be outdated
by Israel G. Lugo 29 Mar '16

29 Mar '16

Hello, I just found out about the "merge external" feature by seeing its commit log: https://gitlab.labs.nic.cz/labs/bird/commit/145368f5474436ad7c48fa26f5bde81… Unfortunately, this is not documented in the website: http://bird.network.cz/?get_doc&f=bird-6.html#ss6.6 It would seem the website is outdated to the documentation. It would be nice if you could please fix that. Regards, -- Israel G. Lugo Núcleo de Redes e Comunicações Direção de Serviços de Informática Instituto Superior Técnico

Hello Martin, Thank you very much for the PDF. Indeed I forgot to check the bird-doc package. A long time ago I installed it from .deb, but since it seemed to be mirrored in the website, I grew accustomed to using the site for reference. The PDF you generated from source will definitely come in handy. Best regards, Israel G. Lugo On 03/28/2016 07:34 PM, Martin Kraus wrote: > On Mon, Mar 28, 2016 at 06:48:19PM +0100, Israel G.

Bird in a DHCPv6 Prefix delegation setup?
by yanosz 28 Mar '16

28 Mar '16

Hei folks, I thinking of playing around with dhcpv6-prefix delegation and bird. However, atm I don't see how to match bird and dibbler. Assuming, that dibbler hands out a prefix to a link local address - bird has to be made aware of this routing information. Do you have any experiences here? What's the usual way for connecting dibbler and bird? Thanks, yanosz

Possibility of adding bgpsec code to the BIRD repo.
by Michael Baer 23 Mar '16

23 Mar '16

I had a question for the development team. My group, and me specifically, have been working on adding BGPsec support into the BIRD code base. We initially hoped to have it merged into the standard BIRD repository and are getting to the point when that would be appropriate. The main question I have is, are you interested in looking at and/or merging the code into your repo, optimally sometime in the next 2-3 months? As background, the current version is built on the BIRD 1.4.5 code base and the BGPsec code can be included, or not, at build time. A slightly older version of the code is available at: http://bgpsec.tislabs.com/. There is still some final updates to the protocol being completed at the IETF. I would want to update the code to that version of the protocol (which is very likely the final version) as well as merge it with the 1.5 code base over the next month or two. -Mike -- Michael Baer PARSONS baerm(a)tislabs.com

Bug: mrtdump file descriptor remains open after reload
by yanosz 23 Mar '16

23 Mar '16

Hei folks, I tried to rotate my mrtdump-files by reloading the configuration. Procedure: 1. Configuration file: mrtdump "/tmp/mrtdump.0"; 2. Start bird 3. Change configuration to mrtdump "/tmp/mrtdump.1"; 4. Open birdc6 - execute: configure /etc/bird/bird6.conf Result: Two file descriptors are open: # lsof | grep mrtdump bird6 28752 bird 7w REG 254,1 9616 262557 /tmp/mrtdump.0 bird6 28752 bird 60w REG 254,1 0 266602 /tmp/mrtdump.1 Looking at the source, I don't see any call to fclose, that could have been triggered. Greetz, yanosz
