Hello, bird6.conf: -------------------------------------------------------------------------- log syslog all; router id 80.50.131.218; listen bgp address 2a03:6600:3::2 port 179 dual; protocol kernel { scan time 20; # import none; export all; } protocol static { route 2a03:6600:4::/48 reject; } protocol bgp leszczyny { local as 44124; neighbor 2a03:6600:3::1 as 44124; hold time 240; startup hold time 240; connect retry time 120; keepalive time 80; start delay time 5; error wait time 60, 300; error forget time 300; disable after error; path metric 1; default bgp_med 0; default bgp_local_pref 0; gateway direct; export all; import all; } ---------------------------------------------------------------------------------------- sadly, BGP is not working, I found that there is no listening socket created on 2a03:6600:3::2 and it refuses connections from 2a03:6600:3::1: 15:10:48.187179 IP6 2a03:6600:3::1.49296 > 2a03:6600:3::2.179: S 515376837:515376837(0) win 5760 <mss 1440,sackOK,timestamp 722432390 0,nop,wscale 6> 15:10:48.191276 IP6 2a03:6600:3::2.179 > 2a03:6600:3::1.49296: R 0:0(0) ack 515376838 win 0 There is already bird (v4) running on that machine listening on 0.0.0.0:179 How to solve this? Can both bird and bird6 (both with bgp protocol configured) on the same machine? Regards -- Adrian Czapek
