Community for small IX
by Piotr Marciniak 23 Jan '18

23 Jan '18

Hello, We are running a small IX for around 20 members. A few months ago we moved on Bird and actually I am trying to add some standard communities to prepend or stop annoucing own prefixes to other members but can’t find examples on Bird docs nor by Google. All I found looks limited only to adding fixed community only. I think it is standard and may both work on filters for main table or via pipe import/export filters. But still – I can’t discover how to get and process (to block export) or announce (with prepend) received community. Could you please direct me (or send) some examples how to do this? Thank you, Peter

Re: Community for small IX - problem with 4B ASN
by Piotr Marciniak 23 Jan '18

23 Jan '18

Dear Advisors ;], Thank you for all posts. But still I do not know how to make Bird working with 4B communities and if I may do this - whether it will be accepted for our peers? In short - I do not know how to adapt to 4B communities following examples: https://gitlab.labs.nic.cz/labs/bird/wikis/Route_server_with_community_base… https://gitlab.labs.nic.cz/labs/bird/wikis/Route_server_with_community_base… Is there any way to enable 4B communities in bird.conf? I do not have any problem with 4B ASn. I set bgp peering sessions from Bird with 4B ASn. Even our IX has AS205082. This is why I put 2 questions: 1. Is it possible to enable 4B ASn for communities in Bird? Will it work with other rouers? 2. Can we use instead private ASn just for community filters? Are they processed corretly by other Internet routers of our peers? Please - do not explain me theoretical difference between 16 and 32 bits. Question is simple - can I use 4B communities for filters? If not - what 16bit "fake ASn" I can use instead safely?

Bird reports an error 'when 'myas' is 4B => so above 65535. See some testing example below: bird> configure Reading configuration from /etc/bird/bird.conf /etc/bird/bird.conf, line 81: Value 165250 out of range (0-65535) The only way this config reports no error is to set here private ASn - fe. 65250. But it will never match our real ASn. Two questions: 1. Is it possible to enable 4B ASn for communities in Bird? Will it work with other rouers? 2. Can we use instead private ASn just for community filters? Are they processed corretly by other Internet routers of our peers? Or maybe there is another work around?

IPv6 multipath static routes with different weights and BFD supervision
by ?????? ?????????? 23 Jan '18

23 Jan '18

Hi BIRD experts, I face some problems on static routes on IPv6. I try to configure multipath static routes that are supervised with BFD. I use the following conf: route <DEST_IPv6> multipath via <NEXT_HOP1_IPv6> weight 10 bfd via <NEXT_HOP2_IPv6> weight 20 bfd; This does not seem to have the expected behavior since I notice that the static routes are configured with the same priority rather than having the less weighted one with higher priority than the more weighted. When I try to check the routes passed to the kernel I notice this: <DEST_IPv6> via <NEXT_HOP1_IPv6> dev eth3 proto bird metric 1024 <DEST_IPv6> via <NEXT_HOP2_IPv6> dev eth5 proto bird metric 1024 The same configuration for IPv4 works as expected... could you, please, give me some initial orientation regarding the issue? The BIRD version is BIRD 1.6.3 on Debian GNU/Linux 8 (jessie)

Bird-1.6: failed configure check and exit status 0
by fatal 22 Jan '18

22 Jan '18

Hello, I'm using bird 1.6.3 on Debian Stretch and am trying to automate the installation and configuration with ansible. Therefore the "configure check" feature of bird comes in handy. Unfortunately the return code is always "0" whether the config is OK or KO. $ sudo /usr/sbin/birdc configure check BIRD 1.6.3 ready. Reading configuration from /etc/bird/bird.conf Configuration OK $ echo $? 0 After invalidating the config file: $ sudo /usr/sbin/birdc configure check BIRD 1.6.3 ready. Reading configuration from /etc/bird/bird.conf /etc/bird/bird.conf, line 7: syntax error $ echo $? 0 I can build my playbook around this with grepping for "Configuration OK" in the output[1], but it would be nice to habe bird return a non zero value if the config check fails. Thanks a lot regards Sam [1] - name: check bird config command: /usr/sbin/birdc configure check register: bird_result changed_when: False failed_when: bird_result.stdout.find('Configuration OK') ==-1

CentOS 7 repo over HTTP
by Logan V. 20 Jan '18

Hi, Is the centos repo available over http instead of ftp? I am using ansible where the yum modules don't seem to deal very well with ftp based gpg key and repo urls. This is the repo I'm referencing: http://bird.network.cz/?download&tdir=centos/7/ Thanks Logan

BUG syntax error on line 57, in bird.conf
by Tyler Bennett 17 Jan '18

17 Jan '18

I am testing our bird routing daemon version to 2.0.0, on archlinux per the pkged version of bird by the archlinux devs. There seems to be an issue with the default bird.conf file that is provided by the bird source code, it errors out on line 57. Does the config file have to be edited before it can be used? I know its an example file, but should it be erroring out. Please let me know if there is anything I can do to help out. I have submitted a bug to archlinux as well: https://bugs.archlinux.org/task/57096

Convert route between protocols
by Jakub Nowacki 16 Jan '18

16 Jan '18

Hi everyone, I'm looking for a way to locally (on a single host) convert a single route between protocols, so that route changes its attributes i.e. originate static route locally and convert it to BGP. Sample configuration: ############################## protocol static my_default { route 0.0.0.0/0 drop; } protocol bgp my_bgp { neighbor 1.1.1.1 as 1; export all; } ############################## In the above host will generate default route and store it locally as static route then it will advertise it to its neighbor as a BGP route. I'm looking for a way for that router to be able to store that route as BGP already. Is it possible? -- Thanks Kuba
