Good day. I want to compile static binary of bird and birdc. I should made little router with a few disk space on an CompactFlash. Now I get come systems binaries (most of them is a BusyBox) all about 4M with a kernel. I never tried to load my little system yet but I should install the bird there. Can You help me ?

several questions and possible(?) bugs

Hello! I'm beginner with BIRD and need some help. And sorry for bad English.. :) If you can help me with only part of questions, please, do it :) I have FreeBSD station with interface em0 (and others), which acts as router. ______________________________________________________________________________ ifconfig em0 em0: flags=8943<UP,BROADCAST,RUNNING,PROMISC,SIMPLEX,MULTICAST> mtu 1500 options=3<RXCSUM,TXCSUM> inet 81.1.226.1 netmask 0xffffff80 broadcast 81.1.226.127 inet 192.168.0.1 netmask 0xfffff000 broadcast 192.168.15.255 ______________________________________________________________________________ and I need to broad/multicast through it three mentioned RIPv2 routes I created config: _____________________________________________________________________________ log "tmp" all; table testable; debug protocols all; protocol static { table testable; debug all; import all; # from the protocol to the routing table export none; route 0.0.0.0/0 via "em0"; route 81.1.226.0/23 via "em0"; route 192.168.0.0/16 via "em0"; } protocol rip RIP { # You can also use an explicit name table testable; export all; import none; debug all; port 520; period 10; interface "em0" { mode broadcast; }; honor never; authentication none; } protocol device { scan time 60; # Scan interfaces every 10 seconds } ______________________________________________________________________________ Questions: 1) I have two aliased IPs on em0, so I need to send broadcast to 81.1.226.127 and 192.168.15.255 both (my third-party MS-windows client doesn't understand multicast). tethereal -i em0 port 520 Capturing on em0 0.000000 81.1.226.1 -> 81.1.226.127 RIPv2 Response 0.000002 81.1.226.1 -> 81.1.226.127 RIPv2 Response 0.000590 81.1.226.1 -> 81.1.226.127 RIPv2 Response How can I make BIRD to send packet to both 81.1.226.127 and 192.168.15.255? And why there are three packets, not just one? 2) Then, I have "period 10" in config, but in the BIRD's log "says" about 2-7 seconds ______________________________________________________________________________ 10-08-2004 23:18:34 <TRACE> RIP: Broadcasting routing table to em0 10-08-2004 23:18:38 <TRACE> RIP: Broadcasting routing table to em0 10-08-2004 23:18:41 <TRACE> RIP: Broadcasting routing table to em0 10-08-2004 23:18:48 <TRACE> RIP: Broadcasting routing table to em0 10-08-2004 23:18:50 <TRACE> RIP: Broadcasting routing table to em0 10-08-2004 23:18:56 <TRACE> RIP: Broadcasting routing table to em0 10-08-2004 23:19:03 <TRACE> RIP: Broadcasting routing table to em0 10-08-2004 23:19:07 <TRACE> RIP: Broadcasting routing table to em0 10-08-2004 23:19:09 <TRACE> RIP: Broadcasting routing table to em0 ______________________________________________________________________________ at the same time dump says about ~28 seconds.

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!!!

Two BGP instances
by Damjan 08 Aug '04

08 Aug '04

Hi, I have Bird running BGP with two peers, and I have two "static" protocols with several routes in them. This is abbreviaded example: protocol static pool1 { routes... } protocol static pool2 { otherroutes... } protocol bgp bgp1 { ...BGP setup for peer1... } protocol bgp bgp2 { ...BGP setup for peer2... } Now I have two questions... Q1: I tried to put pool1 and bgp1 in a separate bird route table, by adding "table table1;" in them, and pool2 and bgp2 in table2. But with that config it seems Bird didn't anounce anything via BGP. Q2: Even better would be if I could make a filter, in the BGP protocols, to find out which static protocol the route has come from, so that I can bgp_path.prepend my AS on routes from pool1 going out to peer2, and on routes from pool2 going out to peer1. But I don't know how to make the condition? if source = "pool1" ? -- damjan | дамјан This is my jabber ID --> damjan(a)bagra.net.mk <-- not my mail address!!!

Both IPv4 and IPv6 at the same time?
by Jacek Konieczny 04 Aug '04

04 Aug '04

I would like to switch to bird (instead of zebra/quagga), but it has one annoying feature: it may be compiled for IPv4 or IPv6, not both. And I need both. Are there any plans to resolve this issue? Or maybe both versions may be used together as two separate binaries? However, that will probably break when multicast routing is in (Linux doesn't like two multicast routing daemons at the same time). Greets, Jacek
