This is fixed, but you have to use a compiled version. It's not released yet.

[rbzchnadm]

I'm currently using the 10.0 compiled version based on released source https://github.com/FRRouting/frr/archive/refs/tags/frr-10.0.tar.gz

The fix is not integrated in this release, right ?

[ton31337]

No, you have to use non-release branch, e.g. stable/10.0.
