Hi there, I am really new to the complete topic of BGP. So please have a bit mercy with me if I ask something very stupid. But I am trying to build that for the first time ever and I am feeling like a donkey in front of a big mountain. Last but not least it is currently running, but I guess its more luck than something else. Like I said I am completely new to the topic of BGP. What I don't get is how I configure them together so they work (as a HA-Cluster) and currently I can only route a.b.c.249/29 instead of a.b.c.0/22. Here is what I am trying to build (https://imgur.com/a/NtWE6MY). And here are my two configs: /* * My example bgp01 configuration */ log syslog all; log "/var/log/bird.log" all; # d.e.f.124/29 is my IP in the transfer network /29 to my peering uplink1 # d.e.f.125/29 is my 2nd bird bgp in the transfer network /29 to my peering uplink1 router id d.e.f.124; define myasn = XXXX; define myaddr = d.e.f.124; protocol device { scan time 10; # Scan interfaces every 10 seconds } ipv4 table master4; protocol direct { ipv4; # Tells bird to only do ipv4 interface "enp3s0f4"; # Restrict network interfaces BIRD works with } protocol kernel { ipv4{ table master4; import all; export all; }; persist; } #a.b.c.0 is my own /22 ip range protocol static static_bgp { ipv4; route a.b.c.0/22 via d.e.f.124; } protocol bgp link1 { local d.e.f.124 as XXXX; neighbor d.e.f.121 as YYYY; #d.e.f.121 is the first router of my peering uplink 1 ipv4 { import all;export where proto = "static_bgp"; }; } protocol bgp link2 { local d.e.f.124 as XXXX; neighbor d.e.f.122 as YYYY; #d.e.f.122 is the second router of my peering uplink 1 ipv4 { import all;export where proto = "static_bgp"; }; } /* * My example bgp02 configuration */ log syslog all; log "/var/log/bird.log" all; # d.e.f.124/29 is my IP in the transfer network /29 to my peering provider1 # d.e.f.125/29 is my 2nd bird bgp in the transfer network /29 to my peering provider1 router id d.e.f.125; define myasn = XXXX; define myaddr = d.e.f.125; protocol device { scan time 10; # Scan interfaces every 10 seconds } ipv4 table master4; protocol direct { ipv4; # Tells bird to only do ipv4 interface "enp3s0f4"; # Restrict network interfaces BIRD works with } protocol kernel { ipv4{ table master4; import all; export all; }; persist; } #a.b.c.0 is my own /22 ip range protocol static static_bgp { ipv4; route a.b.c.0/22 via d.e.f.125; } protocol bgp link1 { local d.e.f.125 as XXXX; neighbor d.e.f.121 as YYYY; #d.e.f.121 is the first router of my peering provider1 ipv4 { import all;export where proto = "static_bgp"; }; } protocol bgp link2 { local d.e.f.125 as XXXX; neighbor d.e.f.122 as YYYY; #d.e.f.122 is the second router of my peering provider1 ipv4 { import all;export where proto = "static_bgp"; }; } Thanks a lot for your help and inputs Best Regards, Yves
