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.

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

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.

How to add IPv6 support?
by Christoph Biedl 07 Oct '10

07 Oct '10

I don't see a single bit about this in the documentation ... For quite some time bird served me very well for dynamic routing within a small network using the BGP method. Until the day when I wanted to enable IPv6 on all routers. The Debian distribution ships two packages, bird and bird6, and as far as I can see the only difference is the latter was compiled using the --enable-ipv6 option. Now what am I supposed to do? Is bird6 supposed to do _all_ the work, v4 and v6? If yes, is it a feature bird6 cannot handle IPv4 addresses in the bgp "neighbor" statement (yields "syntax error")? Prefixing into a v6 address using '::ffff:' survives the parser, but these addresses are not routed. Or should I really start bird6 as a second routing daemon to handle the IPv6 prefixes? This is silly since this means duplication of the configuration file and all the peer detection and route switching is not synchronized. What magic did I miss? Christoph

Vim user?

[ This is a resend, I wasn't a list member when I sent this the first time, and I think it may have been eaten. ] I found myself wishing for some syntax highlighting while setting up a new bird installation this week. Didn't see any vim syntax out there, so I whipped one up. You can snag it here: http://www.vim.org/scripts/script.php?script_id=3263 Enjoy. -- Mahlon E. Smith http://www.martini.nu/contact.html

BIRD crashes caused by quagga OSPF?
by Petr Bradac 05 Oct '10

05 Oct '10

Hi, I'm running two Linux Quagga servers and two BIRD servers inside an OSPF backbone area (brodcast network). The BIRD serveres are running on a FreeBSD 8.1 system with the 1.2.4 BIRD version. The BIRDs are also configured to run a Direct, Kernel, Device, Static and BGP protocol. Unfortunatelly, once a day both the BIRD daemons are crashing at the same time, probably caused by a bug in the OSPF protocol. There are now D.J.B's daemontools supervising the BIRD's processes to overcome the crashes. I can provide you with the BIRD / Quagga logs and a core dump file, if necessary. Thanks for your help. Best regards, -- Petr Bradac AVONET, s.r.o.
