Thank you for your suggestion Yakov,
I added the sections you had mentionned as below and the neighbor is still
unreachable.
I am not a network expert but i am wondering if such a set up is technically
possible.
Do you know?
$ cat /etc/bird.conf
router id <public ip>;
protocol bgp bgp_static {
local as 65001;
neighbor <server 2 public ip> as 65001;
multihop 99;
ipv4 {
import all;
export filter {
if net = 10.1.1.1/32 then accept;
reject;
};
};
debug all;
}
protocol kernel {
ipv4 {
import all;
export all;
};
learn;
persist;
scan time 20;
}
protocol direct {
interface "*";
}
protocol device {
scan time 10;
}
Many Thanks,
tg

Hi,
Since you have only BGP protocol defined, BIRD knows nothing about any routes
that could exist on your system. If you want to import local routes into BIRD
you need to add some other protocols, usually it's 'device', 'direct' and
'kernel'.

Hello,
I rent physical hosts from a public cloud provider and i am trying to set up a
private network between them.
For that, i want to configure BGP protocol between them.
I use Bird 2.15.1 on AlmaLinux 9.2.
Each host has a public ip that i use as « router id » and « neighbor ».
I add a private ip 10.1.1.x on lo interface used for BGP.
birdc show protocol command confirm that the bgp session is established. State
is « up » and Info column displays « Established ».
But birdc show route command is empty; it shows only the following message «
BIRD 2.15.1 ready. ».
The routing tables seems to not be shared between the peers.
There are no errors in the logs (either /var/log/messages nor journalctl).
Do you know if this approach is technically possible?
Herunder the configuration:
$ cat /etc/bird/bird.conf
router id <public ip>;
protocol bgp bgp_static {
local as 65001;
neighbor <server 2 public ip> as 65001;
multihop 99;
ipv4 {
import all;
export filter {
if net = 10.1.1.1/32 then accept;
reject;
};
};
debug all;
}
Many Thanks,
tg
