bird 100% load
by Adam Pribyl 21 Jul '04

21 Jul '04

I am triing to use bird 1.0.7, in my linux distribution based on uClibc, as routing daemon in network where neigbours are serviced by zebra (quagga). After few second after bird starts it consumes cpu runtime to nearly 100%. This seems to last forever. From debug messages I do not see anything unusuall to happen. Most values is set to default. I am using only protocols static and ospf. It also seems quagga's ospfd has some troubles comunicate to bird and crashes sometime, but this is not confirmed. Any ideas? Adam Pribyl

RIPv2, incorrect metric changes
by RATM 22 Jun '04

22 Jun '04

Hi all, I apologize if this topic has already been discussed on the mailing list, but I couldn't find a message archive to check it out. And, I apoligize for my poor English. My problem is that the BIRD RIPv2 daemon doesn't accept a worse metric coming from the router which is the nexthop for that entry. I'll paste some sniffed packet to give the whole idea. This network is very simple - 2 routers (200.0.0.1 and 200.0.0.2) with 4 interfaces each: Frame 1 (106 bytes on wire, 106 bytes captured) Internet Protocol, Src Addr: 200.0.0.1 Dst Addr: 224.0.0.9 Routing Information Protocol IP Address: 200.0.6.0, Metric: 2 IP Address: 200.0.5.0, Metric: 2 IP Address: 200.0.4.0, Metric: 2 /* The metric is 2. */ Frame 3 (106 bytes on wire, 106 bytes captured) Arrival Time: Jun 16, 2004 18:19:14.496397000 Internet Protocol, Src Addr: 200.0.0.1 Dst Addr: 224.0.0.9 Routing Information Protocol IP Address: 200.0.6.0, Metric: 5 IP Address: 200.0.5.0, Metric: 5 IP Address: 200.0.4.0, Metric: 5 /* Here I changed the default metric to 5. And now 200.0.0.1 begins announcing its directly connected networks with a metric of 5; anyway, 200.0.0.2 (whose hostname is r1) doesn't change the metric in its route table as you can see below: r1:~# birdc BIRD 1.0.6 ready. bird> show route 127.0.0.0/8 dev lo [direct1 18:12] (240) 200.0.0.0/24 dev eth0 [direct1 18:12] (240) 200.0.1.0/24 dev eth1 [direct1 18:12] (240) 200.0.2.0/24 dev eth2 [direct1 18:12] (240) 200.0.3.0/24 dev eth3 [direct1 18:12] (240) 200.0.4.0/24 via 200.0.0.1 on eth0 [MyRIP 18:25] (120/2) <---- 200.0.5.0/24 via 200.0.0.1 on eth0 [MyRIP 18:25] (120/2) <---- 200.0.6.0/24 via 200.0.0.1 on eth0 [MyRIP 18:25] (120/2) <---- I left the arrival time information in the second packet to let you compare it with the time displayed in the show route output.

protocol direct + protocol kernel + multitables
by Roberto Moreda 21 Jun '04

21 Jun '04

Hi! I'm trying to use bird as a "propagator" of direct routes defined by interfaces to other tables than the default. Just playing around a bit. My conf is: table test; protocol direct { table test; import all; } protocol kernel { table test; persist; scan time 20; export all; kernel table 2; } protocol device { scan time 10; } If my machine has as main routing table: 192.168.1.0/24 dev eth0 proto kernel scope link src 192.168.1.20 default via 192.168.1.1 dev eth0 ... can I expect to have this entries replicated in kernel table 2? (my results show that I don't get this) Is it possible to do that? Thanks in advance. Roberto

Sorry, my FreeBSD is 4.7 - it is too old for BIRD :-). On FBSD-4.10Beta BIRD even compiles :-), but I can't run BIRD there ... Becouse gated allways running there :-(. Next time I'll try.

Questions about routing filters
by Loschyov Oleg 08 Jun '04

08 Jun '04

Hello I have some difficulties in writing filters. Our company have few IP-tunnels with another company, something like protocol static { .... route 10.1.1.0/24 via 192.168.100.2 .... Everything works fine, but people using the same provider links says that they see my private routes (bird configured for RIP) distributed over network. For them it`s just like garbage :) It`s important routes only for me :) So I need to write a filter for this routes. I`ve written something like this: in /etc/bird.conf ... filter hide_private_routes { if net ~ 10.16.0.0/16 then reject; else if net ~ 10.20.0.0/16 then reject; else if net ~ 10.22.0.0/16 then reject; else if net ~ 10.30.0.0/16 then reject; else if net ~ 10.135.200.0/24 then reject; else accept; } ... protocol rip eXoft_RIP { ... export filter hide_private_routes; ... } Am I correct?

crash
by Przemyslaw Krol 08 Jun '04

08 Jun '04

hello there I've already written post about bird-crash some time ago, but it's happened again. This time it happened after sending about 20 routes via ospf to Juniper. Any suggestions? It was previous release of bird compiled from tarball, running on debian (woody). Thanks in advance, Kind regards Przemek Krol -- ------- chaos, panic and disorder ... looks like my work is done here -------
