Hello,
please tell us more about your setup, config and topology. With this,
we can't even start looking for the possible problem.
Here is config from one of servers, which is affected.
Really any host with bird2.15 is affected, but we run it only on alma 9.
router id 192.168.110.2;
route 192.168.204.1/32 via "wg0";
route X/28 via Z;
route Y/28 via Z;
route 192.168.200.34/32 via Z;
route 192.168.201.66/32 via "gre2";
route 192.168.200.38/32 via "gre1";
protocol ospf MyOSPF {
area 0 {
networks {
192.168.110.0/24;
192.168.201.64/30;
192.168.200.36/30;
};
interface "gre1" {
#
cost 2;
type ptp;
password "111" {
id 10;
algorithm keyed md5;
};
authentication cryptographic;
};
interface "gre2" {
#
cost 1111;
type ptp;
password "111" {
id 10;
algorithm keyed md5;
};
authentication cryptographic;
# bfd yes;
};
interface "br0" {
#LAN
cost 1;
password "111" {
id 10;
algorithm keyed md5;
};
authentication cryptographic;
#check link yes;
};
};
}
As you can see it's just to gre uplinks and br0 to LAN.
We also have area 1 in our ospf, but I don't think it is related.

Please, tell me what other information you need.
Thank you!

etc.
on all hosts I upgraded.
All of them is alma 9.
Downgrade to 2.14 solved problem.
Is there fix for this or workaround?
Thank you!
