Bird-1.0.9 vs Quagga (ex zebra) in a OSPF network
by Damjan 10 Aug '04

10 Aug '04

My network has several Cisco routers, several Linux routers and my workstation is on the same network. The Linux routers have Quagga installed, but on my computer I test both wiht Bird and Quagga. The problem is that Quagga receives all he routes published by the Cisco routers, while Bird doesn't. Even more interesting, from two Cisco routers bird doesn't receive any routes, but from one of the Ciscos bird receives 65 routes while Quagga receives 87 routes. -- damjan | дамјан This is my jabber ID --> damjan(a)bagra.net.mk <-- not my mail address!!!

question about v. 1.0.9 spec file
by Loschyov Oleg 27 Jul '04

27 Jul '04

Hello Everybody. I have some difficulties in disabling IPv6 support for bird-1.0.9-rpm. Of course it`s easy to edit /etc/init.d/bird script to disable starting bird6 startup. But I`m interesting in 100 % disabling IPv6 support in bird (a bit maniac) So first of all, I`ve corrected %build section in bird.spec from: ./configure --prefix=/usr --sysconfdir=/etc --localstatedir=/var --enable-ipv6 to: ./configure --prefix=/usr --sysconfdir=/etc --localstatedir=/var and after that the final %build section looks like that ./configure runs twice with the same options. Is it necessary? May be it`s quite enough to run ./configure only once Next, in %install section i see: %install 1. rm -rf $RPM_BUILD_ROOT/* 2. make install prefix=$RPM_BUILD_ROOT/usr sysconfdir=$RPM_BUILD_ROOT/etc localstatedir=$RPM_BUILD_ROOT/var 3. install bird6 $RPM_BUILD_ROOT/usr/sbin 4. cd $RPM_BUILD_ROOT 5. install -d etc/rc.d/init.d 6. install $RPM_SOURCE_DIR/bird.init etc/rc.d/init.d/bird 7. install $RPM_SOURCE_DIR/birdc6 usr/sbin/birdc6 So I comment out 3-rd & 7-th lines, and in %files section I see 2 lines with setting up attributes for bird6 & birdc6. (I`ve disabled them too). Am I correct?

bird 100% load
by Adam Pribyl 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

Hi all. It seems, that bird 1.0.8 anf 1.0.9 has some memory leak. I use only RIP and I see something like this: root@netserver:~# ps axu | grep bird root 154 0.0 26.7 17788 16768 ? Ss Jul15 0:02 /usr/sbin/bird root@netserver:~# kill 154 root@netserver:~# root@netserver:~# bird root@netserver:~# ps axu | grep bird root 855 0.0 0.9 1608 584 ? Ss 08:54 0:00 bird root@netserver:~# root@netserver:~# ps axu | grep bird root 855 0.0 1.7 2140 1124 ? Ss 08:54 0:00 bird root@netserver:~# I've tried 3 version of bird on 3 differet machines, results was the same :-(. As You can see memory usage is growing ... On one my machine it was 114M today :-(. In my "old" and stable router I use bird-1.0.7 and it is not growing.

I have seen usual information in /tmp/dump.file but nothin new for me. Afte "dump resources" command nothin changes. I have recompiled bird-1.0.9 once moor and it does not grow anymore ... Strange :-( I have backup of "growing" binaries but they does not grow anymoor too ... I only can suspect that there was "enemy" packets in our network which makes bird to grow in memory. Nothings comes in my head... We have a one big ethernet segment with several different ip subnets, all of them may have or may not their own RIP And my bird hears it every time. Tcpdump tells me about our net-tresh but can not do monitoring my net every time. Situation: I have 4 routers. Two of them was configured long time ago and I did not use filters for them, I limit receive RIP packets by iptables from One "trusted" host (there are several misconfigured routers in our net which send wrong RIPs to my machines). The third router I have Installed 3 days ago, I used filter to drop routes coming not from trusted host. 4-th machine is my experimental, I chech filters on in, Some patches and so on. Here is filter: filter drop_suckers { if net != 0.0.0.0/0 then { if from = 217.29.80.1 then accept; else reject; } else reject; } 3 and 4 machines had growing bird-1.0.8 and 1.0.9. On 1 and 2 stands bird-1.0.7 whithout filters and whith firewall. Maybe birds whith Filter gets some packets and gets memory leak ? I have discribed here 4 machines which have mainly the same configs whith little difference - routers ID and filters. Now I don't know any reason why bird was growing ... Becouse it stops growing. I steel can not make bird to do "dump resource" :-).

Use the config option log: log "/tmp/dump.file" all; The output of the dump will be there. OF

Release 1.0.9
by Ondrej Filip 15 Jul '04

15 Jul '04

Hi all! I'm happy to announce the release 1.0.9. Except a minor bugfix in RIP, all of the changes are related to OSPF. It should be fully compatible with rfc2328 now. It means that it support MD5 authentication, multiple OSPF areas, virtual links etc. So, please test it. The next development focus will be the multicast routing procols. (But of course we will fix the bugs and add minor improvements.) Kind regards Ondrej Filip
