The control traffic is carried over IPv6. You are right, 540 is for IPv4. -- Elen sila lumenn' omentielvo Ondrej 'Santiago' Zajicek (email: santiago(a)crfreenet.org) OpenPGP encrypted e-mails preferred (KeyID 0x11DEADC3, wwwkeys.pgp.net) "To err is human -- to blame it on a computer is even more so."

Birdc OSPF propagate connected networks from VLANs
by viker 12 Jan '16

12 Jan '16

Hello everybody, i have a strange problem with propagation of subnets to OSPF area. scheme: --------------- Area 0 ----------------- -- Router1 -- ------------------ -- Router 2 -- --------------- ----------------- | LAGG iface | LAGG iface On both routers are bonded ifaces in LAGG. When i create vlan on LAGG trunk (i'm on FreeBSD 10.2. bird 1.5.0), i have in route export only ip/32 on vlan iface, not whole subnet. Configuration of bird: #### Main #### log "/var/log/bird.log" all; router id XXX.XXX.XXX.XXX; debug protocols all; protocol static { route YYY.YYY.YYY.YYY/NN via "vlanXX"; export all; import all; } protocol device { scan time 120; export all; } protocol kernel { learn; persist; scan time 30; import all; export all; } protocol ospf { import filter { accept; }; export all; area 0.0.0.0 { interface "ix0" { cost 10; type broadcast; hello 10; retransmit 5; wait 15; dead 30; }; networks { 10.0.0.0/8; 172.16.0.0/12; 192.168.0.0/16; }; }; }; Interesting thing is , when i import subnet to main table via :route XXX.XXX.XXX.XXX via "vlanXXX"; in static protocol and do birdc configure, propagation is working. So it seems to me that protocol device (or kernel) is not correctly importing created subnet into main table. Any ideas ?

Turris Omnia - campaign ends soon
by Ondrej Filip 11 Jan '16

Hi BIRD users! I hope you will forgive me one e-mail regarding our other project. As you might know, our company (CZ.NIC) is currently developing not just BIRD, but we are also working on an open source (SW and HW) SOHO router called Turris Omnia. To support our development we launched an IndieGoGo campaign. The campaign will end on Monday, so if you want to buy a great open source router that works very well with BIRD, please check this URL - https://www.indiegogo.com/projects/turris-omnia-hi-performance-open-source-… Kind regards and good luck in 2016!

Hello. Could you tell me status RIP in bird. Is it still broken in Bird? Or it should works fine? I have a problem with rip_metric. -- Best regards, Anton Kiryushkin
