OSPF ptmp
by Борис Коваленко 17 Feb '17

17 Feb '17

Hello! Trying to run bird on ethernet interface with type = ptmp. Yes, I know that ethernet is broadcast interface, but there is a good practice to use ptmp on ethernet. I found a strange bug. When type = ptmp, bird sends only one Hello packet and then stops (and even receive?) next packets until I fully restart bird, while other side (cisco or mikrotik) sends packets every 10s (as configured). There is no problems with type = broadcast Here is my simple test configuration: protocol ospf main_ospf { import all; instance id 0; tick 5; area 0.0.0.0 { networks { X.X.16.78/32; X.X.16.80/28; }; interface "lo1" { type ptp; hello 60; retransmit 10; dead 30; }; interface "em0.102" { cost 10; type ptmp; hello 10; retransmit 5; dead 40; # authentication cryptographic; password "XXXXX" { id 1; algorithm keyed md5; }; }; }; } FreeBSD - 11-STABLE Bird 1.6.3 With regards, Boris -- С уважением, Борис Коваленко

Invalid example for RIPv2 in User's Guide
by Steve Leung 17 Feb '17

17 Feb '17

http://bird.network.cz/?get_doc&f=bird-6.html#ss6.10 In the link above, the RIP section's example will return config error in bird v1.6.3. Is this an outdated example for older version of bird? protocol rip { debug all; port 1520; period 12; garbage time 60; interface "eth0" { metric 3; mode multicast; }; interface "eth*" { metric 2; mode broadcast; }; authentication cryptographic; password "secret-shared-key" { algorithm hmac sha256; }; import filter { print "importing"; accept; }; export filter { print "exporting"; accept; }; } Best regards, Steve

BGP dynamic filtering
by Liran Schour 15 Feb '17

15 Feb '17

Hi all, I want to implement a dynamic filter where I will export a route based on matching against a dynamic set of prefixes. The set is maintained according to a database. 1. Can I maintain a dynamic set of prefixes and change the set on the fly? What are the performance impacts of this? 2.. Where can I find such an example? - Liran

Appeal for Conservation Donations
by Werner van der Walt 12 Feb '17

12 Feb '17

Dear Birders, As many of you may know, the 'Champions of the Flyway' is an annual event that takes place in Eilat, Israel. This year the event is on March 28th. The event takes the form of a Big Day - essentially a midnight-to-midnight race to see which team can record the most species over that time. But more importantly, the race is used as a vehicle to raise funds for the protection of important bird migration flyways. Over 25 million birds are illegally slaughtered by hunters and trappers along these routes each year, and the Champions of the Flyway contributes significant funds to projects combating this. This year the anti-hunting projects of BirdLife's affiliate in Turkey, Doga, is the beneficiary. Teams from all over the world gather in Eilat, itself a migration hotspot, to help the conservation of migratory birds. South African teams have participated in this event for the last few years, and have competed incredibly well in the fundraising aspect, especially considering that we compete with much stronger currencies in the dollar, pound, and euro. We have also traditionally competed well on race day, especially considering that many teams are much more familiar with the Palearctic species present there. This year the South African representation takes on a youth flavour. Our team, the Birding Ecotours 'Youth Africa Birders', is made up of John Kinghorn, Werner van der Walt (both Johannesburg), Jessleena Suri, and Andrew de Blocq (both Cape Town). None of us iolder than 25, and we are representing not only our country but also the Youth Africa Birding movement, of which John is the Chairman and Werner is the Vice-chairman. This movement encourages birding as a hobby for the African youth. We are especially motivated to contribute to Doga's work this year, since a central part of their already-successful project is educating the younger Turkish generation about the negative effects of hunting, and to convert them to bird enthusiasts rather than hunters. We have been preparing for months now by studying books on Middle Eastern birds, listening to calls sourced online, and perusing multiple local blogs to make sure we stand the best chance possible of competing on all fronts. We are hoping to show the birding establishment that we youngsters can mix it with the best of them! In addition to competing on race day and in the fundraising competition, we are also aiming to abide by our team slogan and #BringTheGees to Eilat! The success of past South African teams has been primarily because of the support of the birdwatching community. Past responses to calls for funds have been met with overwhelming generosity, and we are hoping that you will support this very important cause again this year. We are aiming to raise €3500 (plus minus $3700) as a team which will go directly to BirdLife International's Turkish affiliate. If you are able to spare some funds you can be assured that this is a very worthwhile cause - no donation is too big or too small! Official donations to the cause go through the JustGiving link on our official team page, which can be found on the event website as well as at the bottom of this email. If you wish to assist us in getting ourselves over there (costs amounting to approximately $1200 pp), then please do feel free to contact us for more information. Even if you are not able to assist us, please feel free to follow us on our social media! We will be posting relevant, informative articles, team profiles, and you will be able to live this incredible experience vicariously through us. :) www.facebook.com/BEyouthafricabirders/ On twitter as @youthafricabirding Official team page www.champions-of-the-flyway.com/youth-africa-birders/ Just giving link : https://www.justgiving.com/fundraising/COTF2017-YAB Our sincere thanks in advance to all of you! Please do not hesitate to ask any further questions. Yours in Birding and Conservation, John, Werner, Jess, and Andrew

Hello Mark "!" means that BIRD failed to push the route into the kernel. There are several possible reasons for that: 1) There is already a route for that network 2) Kernel is compiled without multipath support 3) Some next hop of the route is not valid Does it work with unipath next hop on the busybox?

Wrong default route announced with OSPF
by Thomas Berger 07 Feb '17

07 Feb '17

Hi all, we have a strange issue with bird and OSPF: We have set up a two redundant firewall clusters, one for external and one for internal routing. The setup is working well, as long as only the active external firewall has bird running. If we start bird on the passive firewall, the wrong Gateway for 0.0.0.0/0 is announced: The passive firewall has no default route in the main table ( until it imports the one from its peer of course) _active firewall ( before and after starting bird on the passive fw)_ bird> show route all 0.0.0.0/0 via 178.19.71.1 on eth1 [kernel1 03:59:51] * (10) Type: inherit unicast univ Kernel.source: 3 Kernel.metric: 4 _internal firewall before the start if the second bird instance_ 0.0.0.0/0 via 10.11.0.1 on fwfwtrans [ppospf 17:39:36] * E2 (150/15/10000) [10.11.0.1] Type: OSPF-E2 unicast univ OSPF.metric1: 15 OSPF.metric2: 10000 OSPF.tag: 0x00000000 OSPF.router_id: 10.11.0.1 _internal firewall after the start if the second bird instance_ 0.0.0.0/0 via 10.11.0.2 on fwfwtrans [ppospf 17:38:03] * E2 (150/15/10000) [10.11.0.1] Type: OSPF-E2 unicast univ OSPF.metric1: 15 OSPF.metric2: 10000 OSPF.tag: 0x00000000 OSPF.router_id: 10.11.0.1 Any idea? -- Thomas Berger BundesIT Piratenpartei Deutschland – Pirate Party of Germany Pflugstraße 9a, D-10115 Berlin, Germany Patrick Schiffer (Vors.), Carsten Sawosch (Stellv.

Is it possible to apply filter on OSPF interfaces within the same area?
by Steve Leung 01 Feb '17

01 Feb '17

Hi, Using OSPF, when receiving some routes from a network interface, by default all routes will be re-advertised to other interfaces within the same area without applying the filter rules. Say in the below example. === protocol ospf myospf { table t_ospf; import filter ifilter; export filter ofilter; area 0 { interface "eth*" { hello 10; retransmit 2; wait 10; dead 300; cost 10; }; }; } === Routes received from "eth1" will be _forwarded_ to "eth2" and bypassed all the filters. Is it possible to configure bird.conf so only some of the routes will be re-advertised? (aka apply filters to interface within the same OSPF area) Creating multiple ospf instance and treat the routes as "external routes" (so filter will apply) is not a good idea for me because the environment is quite dynamic, may even have hundreds of dynamic virtual interface, and I hope I do not need to edit the config file all the time. Thank you so much for your time. Best regards, Steve
