BGP Monitoring Protocol (BMP) support in Bird?
by Baptiste Jonglez 11 Jul '17

11 Jul '17

Hi, I am wondering if somebody is working on BGP Monitoring Protocol (BMP) support in Bird? Note that I'm just asking, I'm not requesting our beloved Bird developers to add this feature with a deadline set to yesterday :) I might try to implement it if nobody else already did. Basically, this is just a way to export BGP data over a TCP connection: http://tools.ietf.org/html/rfc7854 This looks like a useful alternative to dumping to mrtdump files, there are already several free software clients: https://code.google.com/archive/p/bmpreceiver/ http://www.openbmp.org/#!index.md Baptiste

CLI debugging
by micah anderson 12 Oct '16

12 Oct '16

Hi, I wanted to debug the states of a neighbor, but I cannot seem to figure out how to change debugging on the command-line in a way that *seems* according to the argument options: debug (<protocol> | <pattern> | all) (all | off | { states | routes | filters | interfaces | events | packets }) Control protocol debugging via BIRD logs BIRD 1.6.0 ready. bird> debug all states syntax error bird> debug all events syntax error bird> debug cogent states syntax error bird> debug cogent events syntax error bird> debug cogent all bird> The 'all' works, but the others do not. Do I misunderstand the argument option specification? Thanks, micah

[PATCH v3] IPv6 ECMP support fixes for linux v3
by Mikhail Sennikovskii 14 Sep '16

14 Sep '16

Hi all, Here is the third version of the Linux IPv6 ECMP support patch. In addition to v2 version, it fixes ECMP IPv6 route removal. The patch is against bird 1.6 version, but adopting to the int-new branch is strait-forward, and I could send the patch against it if the community wants to integrate it. Regards, Mikhail

bird does not install route to the kernel
by Volodymyr Samodid 13 Sep '16

13 Sep '16

Hi community, i played with bird6 and ospf3 and faced with issue. In my schema bird does not install route to the kernel, but propagates route to another ospfv3 routers. That leads to routing loop. Here is simple schema: eth0 ------- R0 ------- eth1 ------- bridge ------ eth0 ------- R1 ospfv3 made adjacency R0 bird> show ospf neighbors TEST_OSPF: Router ID Pri State DTime Interface Router IP 198.51.100.11 1 Full/BDR 00:34 eth1 fe80::602c:e2ff:fe96:9c41 R1 bird> show ospf neighbors TEST_OSPF: Router ID Pri State DTime Interface Router IP 198.51.100.10 1 Full/DR 00:34 eth0 fe80::88e0:e3ff:fe08:7842 Now add ipv6 address to eth1 on R0 R0# ip a add 2001:DB8::1/64 dev eth1 on R1, got next bird> >>> TEST_OSPF > added [best] 2001:db8::/64 dev eth0 bird> show route 2001:db8::/64 dev eth0 [TEST_OSPF 13:58:11] * I (150/10) [198.51.100.11] R1# ip -6 ro s fe80::/64 dev eth0 proto kernel metric 256 pref medium added ipv6 address to eth0 on R0 R0# ip a add 2001:DB8:1::1/64 dev eth0 on R1 bird> >>> TEST_OSPF > added [best] 2001:db8:1::/64 via fe80::88e0:e3ff:fe08:7842 on eth0 >>> kernel1 < added 2001:db8:1::/64 via fe80::88e0:e3ff:fe08:7842 on eth0 bird> show route 2001:db8::/64 dev eth0 [TEST_OSPF 13:58:11] * I (150/10) [198.51.100.11] 2001:db8:1::/64 via fe80::88e0:e3ff:fe08:7842 on eth0 [TEST_OSPF 14:05:31] * I (150/20) [198.51.100.10] R1# ip -6 ro s 2001:db8:1::/64 via fe80::88e0:e3ff:fe08:7842 dev eth0 proto bird metric 1024 pref medium fe80::/64 dev eth0 proto kernel metric 256 pref medium R1## ip monitor route 2001:db8:1::/64 via fe80::88e0:e3ff:fe08:7842 dev eth0 proto bird metric 1024 pref medium I can add such route manual.

bird on Xenial doesn't restart after reboot
by Neil Jerram 12 Sep '16

12 Sep '16

Is this the right place to report and discuss an apparent bug with packaging in ppa:cz.nic-labs/bird ? If not, please advise where would be better. If it is the right place... I'd like to report that bird on Xenial doesn't restart after a reboot, using bird version 1.6.0-1+xenial+1 from http://ppa.launchpad.net/cz.nic-labs/bird/ubuntu xenial/main amd64. It appears the package is a bit inconsistent in its init system handling: - It installs init configuration files for SysV, upstart and systemd. - Its postinst (install-time) script calls 'update-rc.d bird defaults' and 'invoke-rc.d bird start'. On Xenial (which uses systemd), the invoke-rc.d call goes through to systemd - or at least, systemctl status bird indicates running after an 'invoke-rc.d bird start', and inactive after an 'invoke-rc.d bird stop' - but the update-rc.d call does not call on to 'systemctl enable bird'. Hence the observation that bird is not restarted on reboot. Thoughts? From analogy with other packages (that are systemd-enabled when installed), I think the fix may be as simple as: - adding '--with systemd' to the dh invocation - adding dh-systemd as a build dep. Thanks, Neil

Question about graceful restart timer
by Robert Wein 25 Aug '16

25 Aug '16

Hello bird users, one of our VIX customers (RS-Client) came up with a question about the graceful restart timer. At his Cisco he found: ------------ Graceful Restart Capability: advertised and received Remote Restart timer is 0 seconds ------------ We don't have anything related to graceful restart in our config, defaults should apply. At packet level, I found in BGP Open sent from bird: ------------ Capability: Route refresh capability Type: Route refresh capability (2) Length: 0 Capability: Graceful Restart capability Type: Graceful Restart capability (64) Length: 2 Restart Timers: 0x0000 0... .... .... .... = Restart: No .... 0000 0000 0000 = Time: 0 ------------ Next, I tried to set the timer explicitly, which ended up again with restart timer 0 in BGP Open. The only way to get the correct timer in the packet was to set graceful to yes in the protocol definition. ------ graceful restart time 10; graceful restart yes; ------ As far as I understand the default for graceful restart ("aware") should be enough to advertise capability and timer. I am grateful for every advice, regards Robert -- www.vix.at | www.aco.net robert.wein(a)univie.ac.at | RW2586-RIPE Vienna University Computer Center Tel: +43 1 4277-14046 | Fax: -14338

Does anyone know what happened to this patch/discussion: http://bird.network.cz/pipermail/bird-users/2016-February/010192.html I believe it (or similar) is needed for IPv6 merge paths to work, and I'm interested in that working. Thanks, Neil

New in BIRD
by Ilias Pallikarakis 23 Aug '16

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
