how to confirm which capabilities have been negotiated
by Eiichiro Watanabe 24 Oct '11

24 Oct '11

Hello, Do we have an appropriate command to show which BGP capabilities have been negotiated on bird after a peer has been established? Of course, I known I can recognize when I look into packets captured, or confirm it on the neighbor router by using "show ip bgp neighbor x.x.x.x" command (in the case of CiscoIOS). it wouldn't be smart. Thanks, eiichiro -- ################################################### Eiichiro Watanabe Internet Multifeed Co.

BIRD at MSK-IX
by Mikhail A. Grishin 27 May '11

27 May '11

Hi, We successfully finished the process of adaptation BIRD to MSK-IX network. Currently BIRD is running on both IPv4 Route Servers (version 1.2.0 with some patches from Ondrej Zajicek). Also we modified our public Looking Glass service. It's available via: http://www.msk-ix.ru/eng/lookingglass.html Thank you for help and cooperation! -- Mikhail A. Grishin E-mail: magr(a)ripn.net

ECMP/multipath support
by Vincent Bernat 06 Jan '11

06 Jan '11

Hi! BIRD does not support EMCP yet. Looking at the source code, BIRD seems to be able to support ECMP routes internally by adding attaching several route attributes to the same route entry. Is there already someone working on this? ECMP is an important feature when dealing with redundancy. Thanks.

Any IX willing to share their config?
by James Montz 27 Dec '10

27 Dec '10

We are a new Internet Exchange in Minneapolis, MN, USA. Currently evaluating BIRD as our route server. Basic config working in lab with both IPv4 & IPv6 daemon. Would like to see another IX's configuration to see how they are handling filtering, sessions, convention, etc. Thank you in advance, James C.

bird6.conf & Router ID
by Matthias Waehlisch 25 Nov '10

25 Nov '10

Hi all, just a quite stupid question but I'm struggling with the bird6 configuration. I want to configure the router ID as follows: --snip-- router id 2a00:cd0:1000:47::2; --snap-- But the error message "Router IDs must be entered as hexadecimal numbers or IPv4 addresses in IPv6 version" appears. Using an embedded IPv4 address does not work, as well. It is BIRD 1.2.3. Thanks matthias

Problem with bgp_local_pref on peer and filter
by Przemysław Knycz 21 Nov '10

21 Nov '10

Hello! I have wird problems with settings bgp_local_pref to routes imported from peer. Version 1.2.4 and 1.2.5. My conf: filter bgp_import_prefix { if (net ~ [ 0.0.0.0/0 ]) then reject; bgp_local_pref=150; accept; } filter bgp_export_prefix { if (net ~ [ 213.5.248.0/21, 88.135.160.0/19 ]) && (source = RTS_STATIC) then accept; reject; } protocol bgp EPIX_RS1 { description "EPIX"; local as 50188; neighbor 195.191.170.1 as 50607; default bgp_local_pref 100; import filter bgp_import_prefix; export filter bgp_export_prefix; } I've checked, filter works when i add "quitbird". Wird was that once it works i've local_pref for this feed 150, but when i've restarted, it sets to 100... I don't know why it doesnt work. I've also changed "default bgp_local_pref" to 150, but it still sets to 100 ;-/ Unfortunatly at doc there isnt any sample with using bgp_local_pref at all :( Please help! Regards. -- .
