Route table 100, 101 on the R-01 side and route table 100 on the R-02 side do not distribute.

This seems to be a similar issue with his task https://vyos.dev/T7297

Details

Version: 1.4.2
Is it a breaking change?: Perfectly compatible
Issue type: Bug (incorrect behavior)

I can confirm the issue exists in what will become VyOS 1.4.3 as this is a bug in the FRR codebase itself and not the VyOS CLI configuration.

Upgrading to VyOS 2025.06.24-0020-rolling current which already uses FRR 10.2 make the redistribution appear:

dmbaturin changed Is it a breaking change? from Unspecified (possibly destroys the router) to Perfectly compatible.

Any updates on this? We're running 1.4 and this is holding back required changes in our configuration.

@hedrok could you re-check and mark as solved if all work as expected?

It is fixed.

Viacheslav closed this task as Resolved.Sep 15 2025, 11:29 AM

Viacheslav moved this task from Open to Finished on the VyOS 1.5 Circinus board.

Viacheslav moved this task from Backlog to Finished on the VyOS 1.4 Sagitta (1.4.4) board.

Ergo: Upgrading to 1.4.4 fixes this?

Yes, it will be fixed in release 1.4.4.

When is 1.4.4 planned for release?

Sorry, please consult about dates of releases with support.
