Hi, Is it still necessary to build custom kernel to get md5 auth working? I got message "Error: Kernel MD5 auth failed” on FreeBSD 11.1 and bird 1.6.3. -- Peter Andreev MSK-IX/RIPN +7 (495) 737-0685 DNS Network Operational Center +7 (499) 192-9179

BIRD 1.6.3 + ROA crashing issue
by Javor Kliachev 23 Mar '18

23 Mar '18

Hello, We have been using BIRD 1.6.3 on Ubuntu 16.04 as Route Server for a long time. Recently we decided to implement a ROA check filtration but we're experiencing the daemon is crashing whenever removing roa table from the file config even when the roa table is not applied anywhere. In simple words: The ROA table is only defined in the config. Here is а specific example: root@rs2-lab:/usr/local/bird-new/etc# cat roa.conf roa table r65501 { roa 1.2.3.0/24 max 32 as 65501; } ################################# *Here is our simple bird config:* root@rs2-lab:/usr/local/bird-new/etc# cat bird.conf log "/var/log/bird.log" all; log syslog all; debug protocols { events }; router id 10.10.10.100; define myas = 12345; protocol device {} include "roa.conf"; ################################# So when I remove/comment "roa.conf" from the config - bird process is crashing /root@rs2-lab:/usr/local/bird-new/etc# birdc c// //BIRD 1.6.3 ready.// //Connection closed by server/ *Here is dmesg with the crash info:* /[62285.414645] bird[11272]: segfault at 0 ip 000000000040ace7 sp 00007ffd5040e950 error 4 in bird[400000+74000]// //[62508.998315] bird[11487]: segfault at 0 ip 000000000040ace7 sp 00007ffe148741c0 error 4 in bird[400000+74000]// //[62599.558242] bird[11570]: segfault at 0 ip 000000000040ace7 sp 00007ffdfa129070 error 4 in bird[400000+74000]// //[62649.377296] bird[11575]: segfault at 0 ip 000000000040ace7 sp 00007ffd5d8da0a0 error 4 in bird[400000+74000]// //[63895.137084] bird[11730]: segfault at 0 ip 000000000040ace7 sp 00007ffdd4f08f00 error 4 in bird[400000+74000]// //[63927.053383] bird[11738]: segfault at 0 ip 000000000040ace7 sp 00007ffe9c5c8110 error 4 in bird[400000+74000]// //[66260.552622] bird[13629]: segfault at 0 ip 000000000040ace7 sp 00007ffc58de2ad0 error 4 in bird[400000+74000]// //[69835.274826] bird[14098]: segfault at 0 ip 000000000040ace7 sp 00007ffe306bc640 error 4 in bird[400000+74000]// //[70481.342658] bird[14218]: segfault at 0 ip 000000000040ace7 sp 00007ffd556c04c0 error 4 in bird[400000+74000]// //[70587.636343] bird[14234]: segfault at 0 ip 000000000040ace7 sp 00007ffdbc90e4d0 error 4 in bird[400000+74000]/ Could someone BIRD developer can help on this issue?

OSPF over OpenVPN
by Michael McConnell 22 Mar '18

22 Mar '18

Hello all, I am trying to establish OSPF over OpenVPN without any luck. The client side always turns up with no neighbours. I’ve tried pointtopoint and exclusively listing my neighbours all with no luck. I originally was using the tun interface and switched to tap hoping that would help, but still nothing. Below are my configurations, does anyone see anything obvious that I am missing? Thanks so much for your time and thoughts! === show ospf ospf1: RFC1583 compatibility: disabled Stub router: No RT scheduler tick: 1 Number of areas: 1 Number of LSAs in DB: 1 Area: 0.0.0.0 (0) [BACKBONE] Stub: No NSSA: No Transit: No Number of interfaces: 0 Number of neighbors: 0 Number of adjacent neighbors: 0 Server === protocol ospf { import all; export filter { ospf_metric1 = 1000; if source = RTS_STATIC then accept; else reject; }; area 0 { networks { 10.40.32.0/24; 10.10.10.32/27; }; interface "bond1" { type broadcast; cost 5; hello 5; wait 10; dead 25; authentication cryptographic; password “boogers"; }; interface "tap*" { type broadcast; cost 5; hello 5; wait 10; dead 25; authentication cryptographic; password “boogers"; }; interface "*" { cost 1000; stub; #type pointopoint; }; }; Client === protocol ospf { import all; export filter { ospf_metric1 = 1000; if source = RTS_STATIC then accept; else reject; }; area 0 { networks { 10.40.32.0/24; 10.10.10.32/27; }; interface "bond1" { type broadcast; cost 5; hello 5; wait 10; dead 25; authentication cryptographic; password “boogers"; }; interface "tap*" { type broadcast; cost 5; hello 5; wait 10; dead 25; authentication cryptographic; password "boogers"; }; interface "*" { cost 1000; stub; #type pointopoint; }; }; -- Michael McConnell WINK Streaming; email: michael(a)winkstreaming.com toll free: 877-GO-4-WINK x 7400 direct: +1 312 281-5434 cell: +506 8706-2389 skype: wink-michael web: http://winkstreaming.com

Patch to output JSON from BIRD
by Alistair Crooks 22 Mar '18

22 Mar '18

Hi folks, I've attached a patch which outputs JSON from BIRD - this is used to save some cycles - where previously we converted to JSON externally, this patch enables output directly in JSON. This is based on bird-1.6.3_4 (from FreeBSD ports) Best, Alistair

Static Route /24
by Michael McConnell 21 Mar '18

21 Mar '18

Hello fellow Bird users, I’ve run into a strange issue trying to subnet a /24 into a series of smaller /27 and /28’s and have the routed via BGP. I currently do the following; route 10.10.10.0/24 reject; However if I don’t bring the interface up as a /24 (i.e. ifconfig eth0:10 10.10.10.10 netmask 255.255.255.0 up) I am unable to get the route explored when I run show route - the interface needs to be online in order for “show route” to show the import as a unreachable. I can kinda make this work through a series of strange static routes, but this seems incorrect. Can anyone suggest a better way to ensure my /24 is announced regardless so that I can then subnet it down for the purpose of serving over a VPN the /28’s and /27’s? Hopefully that question makes sense and isn’t too much nonsense. Thanks for you help and comments!

constant not available everywhere and passing variables from protocols
by Saku Ytti 21 Mar '18

21 Mar '18

My config: define local_ip = 129.250.14.127; define default_candidate_net = 129.250.0.0/16; define default_candidate_ip = 129.250.0.0; define default_net = 0.0.0.0/0; include "common.conf"; protocol static { route 0.0.0.0/0 recursive default_candidate_ip; } # ens192 protocol bgp active from NTT { neighbor 204.141.224.0; } # ens 224 protocol bgp backup from NTT { neighbor 204.141.224.2; } 1) constant not available everywhere a) this works - define default_candidate_ip = 129.250.0.0; - route 0.0.0.0/0 recursive default_candidate_ip; b) this does not - define default_route = 0.0.0.0/0; - route default_route recursive 129.250.0.0; Why not? It barfs with 'line 10: IP address expected' 2) passing variables from protocols I'm thinking how to tell which neighbour is backup which is primary. My thoughts a) 'import (backup, bgp_in) => no way to define >1 filter? b) 'bool backup = true' => no way to set variables in protocols c) 'define backup = true' => no way to set constants in protocols d) ''import bgp_in(true)' => no way to pass variables to filters I resorted to matching to protocol name, and call the backup group backup. But I'd really prefer way to give neighbour or protocol some information I can use in filter to discriminate. Are constants considered strings? If so, should the strings have some methods, like split, sub, []? I bit needlessly need to define 129.250.0.0 and 129.250.0.0/16 as one is used as static route next-hop another is used as filter to permit prefix. I could just maybe say 'default_candidate_net.split('/')[0]'. -- ++ytti

MPLS Support Question
by t a 20 Mar '18

20 Mar '18

We use BIRD in our production network and are considering rolling out a work-around to partially support MPLS functionality. However, before doing so we were wondering what the timeline is for adding additional support for MPLS label support on v2.0+. Thank you.
