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. Sorry for this question. -----Original Message----- From: Ondrej Filip [mailto:feela@network.cz] Sent: Tuesday, June 08, 2004 2:51 PM To: Zharovtsev, Anton Cc: bird-users(a)bird.network.cz Subject: Re: FreeBSD On Tue, 8 Jun 2004, Zharovtsev, Anton wrote: > Hi friends. > > Can You tell me how to compile the BIRD under FreeBSD ?

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

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 -------

RE: Print function

Print prints nothing, but ... It seems that bird show "from" only for routes going though "gw" than is not a "from". E.g. bird shows "from" if "from" != "gw" :-). Sorry, I never seen befor all my 160 routes Becouse it is too match to read. When I sow all routes I sow some "from". Modifer "all" gives more information but it does not show "from" too if "from" != "gw". Ohh ... May be the realm patch has destroed function print ? So I can live without print :-). I will wait official bird release with a realm support. -----Original Message----- From: Martin Mares [mailto:mj@ucw.cz] Sent: Thursday, May 27, 2004 3:47 PM To: Zharovtsev, Anton Cc: bird-users(a)bird.network.cz Subject: Re: Print function Hello!

Print function

Hi friends. Today I have diside to fix some RIP with our clients (in my company) and I find that I can not find any messages from print function called from filters. First I hav tried to find host sending me RIP with wrong routes. I tried: bird> show route table master where from != 217.29.80.1 81.1.232.240/29 via 217.29.81.17 on eth0 [TestRIP 11:23] (120/2) 127.0.0.0/8 dev lo [direct1 May15] (240) 81.1.238.0/23 dev eth0 [direct1 May15] (240) 217.107.206.0/23 dev eth0 [direct1 May15] (240) 172.16.27.0/24 dev eth0 [direct1 May19] (240) 217.29.80.0/23 dev eth0 [direct1 May15] (240) via 217.29.80.206 on eth0 [TestRIP 11:23] (120/2) And that was all about routes. How can I see "from" of this routes ? Then I tried to write filter which must print "from" but any my filters prints nothing, for example: bird> show route table master filter {print "qqqqq";} bird> Where should I find "qqqqq" ? :-) Any ideas ? Best regards. warm

ok, that is good idea. But,what I want is to be sure what if (for example) link up to intermediate switch (or router) of 1st provider fails, the packets go through 2nd provider channel. >>Hi, Oleg. >> >>Try to write two different filters for Your providers and apply them >>separatly in >>Exporting from each RIP to master table or even to separate table. >> >>May be You should simply drop nets of first provider coming from second >>and visa vesta ? >> >>P.S.

Hi, Oleg. Try to write two different filters for Your providers and apply them separatly in Exporting from each RIP to master table or even to separate table. May be You should simply drop nets of first provider coming from second and visa vesta ? P.S. I know You are doing load balancing , aren't You ? :-) -----Original Message----- From: owner-bird-users(a)atrey.karlin.mff.cuni.cz [mailto:owner-bird-users@atrey.karlin.mff.cuni.cz] On Behalf Of Loschyov Oleg Sent: Monday, May 24, 2004 1:49 PM To: bird-users(a)bird.network.cz Subject: routing filter problems Hello, I`m having some problems in making bird filters.

hello there i've been subscribed to this list for a month or so, but can't see many posts, so if my problem is known please do not flame ;-); well the case is quite easy, once upon a time bird ( running ospf ) just stopped comunicating with adjacent router; no hangs, no dumps; just stopped telling about his routes; restart has helped; any suggestions? thanks in advance
