Hello @uf53,
I think this is not a bug.
You can see the same behavior on Debian or other distributives when. you configure IP address manually.
Why do you think that this is a bug?

Hello Dmitry

Thank you for the answer!
vyos calculates the broadcast address automatically also and I don’t find the option in configure mode to change it later.
normally the broadcast address depends on the ip address and network mask, in my case 192.168.167.255 would be correct in my opinion.
I have concerns that bcast 0.0.0.0 can cause unwanted side effects in certain situations.
I also checked other linux installations e.g. ubuntu, centos that all have the correct bcast address.
regards, Urs

Yes, it makes sense.
When don’t set the broadcast address, by default it 0.0.0.0. This appears only in rolling releases, in 1.2.5 all properly.
I propose to create a bug report on the https://phabricator.vyos.net/
