Hi, 

if I can see correctly Calico is still using BIRDv1 that they keep alive themselves...

Since last version of BIRDv1 was released in 2019 (so 7 years ago) and it was subsequently made end-of-life in 2023, we do not upstream any fixes to that version anymore.
In fact we really advise against using BIRDv1 in any serious operation. 

Any issues with BIRDv1 should be resolved by upgrading to BIRDv3 or BIRDv2. In case the issue persists, report it to us then, and we will be more than happy to fix it in our supported versions.

Supporting three versions at the same time is above current capacities of our team. 

Hope this helps,
David

Hi,

We faced the same problem discussed here https://github.com/projectcalico/bird/issues/95

According to the message https://github.com/projectcalico/bird/issues/95#issuecomment-2373663908 this bug should be fixed.

Still can't find whether these patches was included into main branch.
