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

scan time of protocol kernel
by Владислав Гришин 28 Jul '10

28 Jul '10

Hi, Now 'scan time' set to 60 sec. The bird load system up to 100% during 10-12 sec every 60 sec. What circumstances to take into consideration that it is correct to set 'scan time' of protocol kernel? If I do not add paths with linux the console, whether I can delete 'scan time' from the protocol kernel? Vladislav Grishin

bird6 spontaneous crash
by Robert Wein 27 Jul '10

27 Jul '10

Hello, in our testing environment I experienced two strange spontaneous crashes with bird6 1.2.3, running on debian 5.0.5 (amd64). The binary is from build-ipv6 directory of a debian build and with symbols (unstripped). I've got here: bird6-binary, two coredumps, loglines, logfiles and the config. May I ask for somebody of the developers team to take a look at those files? Thank you and best regards Robert -- www.vix.at | www.aco.net robert.wein(a)univie.ac.at Vienna University Computer Center

Error after I add RTS_OSPF_EXT in filter
by Владислав Гришин 14 Jul '10

14 Jul '10

I change filter from filter import_exclude_default { if ( source != RTS_BGP && net != 0.0.0.0/0 ) then { print "net accepted:", net; ospf_metric1 = 60; accept; } reject; } to filter import_exclude_default { if ( source = RTS_OSPF_INT && net != 0.0.0.0/0 ) then { print "net accepted:", net; ospf_metric1 = 60; accept; } reject; } after 'configure soft' I see error bird> configure soft Reading configuration from /etc/bird.conf /etc/bird.conf, line 167: RTS_OSPF_INT: variable expected. bird>

Whether are compatible Cisco IOS and BIRD at usage OSPF MD5 of authentification?
by Владислав Гришин 13 Jul '10

13 Jul '10

I have of two bird (bird1 and bird2 ) and two Cisco devices (cisco1 and cisco2). I have decided to confirue OSPF MD5 authentification. Whether are compatible Cisco IOS and BIRD at usage OSPF MD5 of authentification? Config of Cisco devices. interface Vlan550 ip address 10.10.1.3 255.255.255.128 ip ospf authentication ip ospf message-digest-key 1 md5 7 0636092546420B12034347 ip ospf priority 5 Config of bird devices interface "eth1.550" { hello 10; retransmit 5; cost 10; transmit delay 1; dead count 4; wait 40; type broadcast; priority 0; authentication cryptographic; password "Prjcsalfr45"; }; Cisco1 with cisco2 have installed the neighbourhood with each other. Bird1 and bird2 have installed the neighbourhood with each other, but CiscoХ birdХ not. Give examples of configs if exist. Vladislav Grishin

ospf netmask mismatch
by Martin Kraus 12 Jul '10

12 Jul '10

Hi. I have bird 1.2.2 running on debian lenny on two routers connected by a nonbroadcast configuration. first router has 212.71.191.77/30 on its interface, the second 212.71.191.78/30. They can't negotiate ospf and I get this in the log: bird: OSPF: Bad HELLO packet from 212.71.191.77 - netmask mismatch (255.255.255.128) both routers have additional private prefixes from /25 on their interfaces. Is there a problem with such a setup? it works fine on older birds in the rest of the network. thanks for any pointers mk

Delay after interrupt output
by Владислав Гришин 12 Jul '10

12 Jul '10

BGP protocol receive full view. If during review of the table of routing by ' show route ' command to interrupt output having pressed a key ' q ', bird long thinks. I wait for appearance ' bird> ' approximately 7 seconds. Such delay on Cisco routers is not present. With such delay it is very inconvenient to work with birdc. Bird works on the computer with the processor Pentium(R) Dual-Core CPU 2.50GHz and RAM 2048MB. top - 12:04:06 up 1 day, 17:44, 4 users, load average: 0.20, 0.17, 0.12 Tasks: 75 total, 2 running, 72 sleeping, 1 stopped, 0 zombie Cpu0 : 0.7%us, 0.3%sy, 0.0%ni, 99.0%id, 0.0%wa, 0.0%hi, 0.0%si, 0.0%st Cpu1 : 45.8%us, 54.2%sy, 0.0%ni, 0.0%id, 0.0%wa, 0.0%hi, 0.0%si, 0.0%st Mem: 2065884k total, 457820k used, 1608064k free, 148148k buffers Swap: 4192956k total, 0k used, 4192956k free, 112580k cached It is a bug or a feature?
