Determine Address Family (IPv4 or IPv6) in configuration file at runtime
by Sergey Popovich 13 Aug '13

13 Aug '13

Having mostly identical configurations for IPv4 and IPv6 BIRD (especially routing policies) with few AFI specific parts we try to aggregate common part for both IPv4 and IPv6 in external include file. However there is need in some branch parts to known address family at configuration file processing by bird: for example to properly use maximum prefix length (IPv4: 32, IPv6: 128). Is there are any way to known (some constant, etc.) in configuration for which AFI bird was build? -- SP5474-RIPE Sergey Popovich

stripped binaries
by Alexander V. Chernikov 02 Aug '13

02 Aug '13

Hello list! Currently tools/Makefile.in explicitly strips every binary it installs via '$(INSTALL_PROGRAM) -s'. Usually INSTALL_PROGRAM already has '-s' set (unless user specified he wants unstripped binary) Can we please remove the second '-s' ? P.S. IIRC this was already discussed but I can't find it.

Init scripts from BIRD RPMs
by Arnaud Gomes-do-Vale 02 Aug '13

02 Aug '13

Hi folks, The RPM packages provided on bird.network.cz have a single init script for managing both bird and bird6. This script has some heuristic rules to determine which daemon(s) to manage, but its status subcommand is unable to recognize "I am managing only one daemon" from "the other one has crashed". Basically, "service bird status" is broken; furthermore, the "one init script for two daemons" model makes it awkward to manage BIRD with Puppet. I have rebuilt the latest package locally with separate init scripts for bird and bird6 as a workaround for this issue. I have also ripped out the whole "check whether we need this daemon" logic as it makes no real sense with separate services. HTH, -- A

Hello. I have some problem with ecmp in bird. We try to migrate from quagga to bird and have faced with ecmp problem in our schema. schema r0-2 - are Linux routers,debian, with bird 1.3.10-1 from debian repo. Both r1,r2 inject default route to area 1 as expected. But r0 inject to kernel only one route. r0 bird> show route 0.0.0.0/0 via 10.200.1.101 on eth0 [onat_ospf 13:05] * IA (150/1010) [10.200.2.101] 10.200.1.0/24 dev eth0 [direct1 18:05] * (240) dev eth0 [onat_ospf 18:20] I (150/10) [10.200.2.100] bird> show ospf lsadb Area 0.0.0.1 Type LS ID Router Age Sequence Checksum 0001 10.200.1.10 10.200.1.10 660 8000008a 2fc1 0003 0.0.0.0 10.200.2.100 947 80000029 64ad 0002 10.200.1.100 10.200.2.100 963 8000002e c3a4 0001 10.200.2.100 10.200.2.100 547 80000083 796c 0003 0.0.0.0 10.200.2.101 967 8000002c 58b5 0001 10.200.2.101 10.200.2.101 955 80000079 8b61 bird> show ospf state area 0.0.0.1 router 10.200.1.10 distance 0 network 10.200.1.0/24 metric 10 router 10.200.2.100 distance 10 network 10.200.1.0/24 metric 10 xnetwork 0.0.0.0/0 metric 1000 router 10.200.2.101 distance 10 network 10.200.1.0/24 metric 10 xnetwork 0.0.0.0/0 metric 1000 network 10.200.1.0/24 dr 10.200.2.100 distance 10 router 10.200.2.100 router 10.200.1.10 router 10.200.2.101 r0:~# ip ro sh default via 10.200.1.101 dev eth0 proto bird 10.200.1.0/24 dev eth0 proto kernel scope link src 10.200.1.10 With quagga all fine. r0# show ip route Codes: K - kernel route, C - connected, S - static, R - RIP, O - OSPF, I - IS-IS, B - BGP, A - Babel, > - selected route, * - FIB route O>* 0.0.0.0/0 [110/1010] via 10.200.1.100, eth0, 00:00:35 * via 10.200.1.101, eth0, 00:00:35 O 10.200.1.0/24 [110/10] is directly connected, eth0, 00:00:35 C>* 10.200.1.0/24 is directly connected, eth0 C>* 127.0.0.0/8 is directly connected, lo I have found some reference in ospf doc about it ecmp switch [limit number] but if I understand right, this refers only for ospf behavior.

[RFE] Include several files
by Arnaud Gomes-do-Vale 02 Aug '13

02 Aug '13

[ Posting again from my subscribed address, looks like it didn't get through the first time. ] Hello, If I'm not mistaken, the global option "include" can only include one file at a time. Would it be possible to make it include a glob, or maybe the contents of a whole directory? Something like "include mydir/*.conf" would be invaluable for managing BIRD with tools like Puppet. Thanks, -- Arnaud

Hello All.. I am pleased to announce to you that our primary Route server now runs on BIRD. We have noticed some improvement in our Traffic though there is still some work to be done. Effort are ongoing to optimize the system though support is somewhat arduous. A special thanks to the following people for their suggestions and help 1. Mo shivji 2. Ondrej Filip 3. Matjaz Straus 4.Andy Davidson And a host of others whom I might have forgotten. I plan to write a presentation paper for the benefit of the African continents and would appreciate a review from some of you when done. Regards Anibe Onuche
