Dear CentOS-Community, we are facing the following issue: A secondary ip address seems to be automatically added to a nic which causes several issues in our setup.

Hi, Tonight I upgraded two CentOS 8 boxes to CentOS 8.1 (1911). Then after a reboot of the first server the network was unavailable. In IPMI console everything except the network was looking good. Network was unreachable. No errors in NetworkManager. I also restarted NetworkManager, but it did not help. Then I discovered that the default gateway suddenly was missing. Then I rebooted the
