Configuring Default Select Logic for Network

[okdlukas]

In my OKD Cluster of 3 Master and Several Worker Nodes + 1 Service Node i have several VLANS to pick from. I use a bare metal install with Fedora Core OS which makes the extended Network configuration a bit complicated at times. By now every Worker gets its first Network Config via PXE BOOT, while the Masters are in a Proxmox Virtual Environment and get their setup via Kernel BOOT Arguments.

It works as long as i only use one VLAN for the Cluster. But when i try to add an additional Network at BOOT via Ignition or PXE the Cluster takes that VLAN as default. Neither Pxe Setup Changes nor adding additional Manifests for setting up the IP selection logic could prevent OKD from chosing the wrong VLAN as default.

In the Setup there should be one VLAN for the cluster and the other one for Storage (iscsi).

I changed the content to better describe the problem.

I looked into that Problem. Currently i have more than one default NIC shown when i log into the worker with SSH. That is probably linked to some configuration in the PXE-Boot for the Worker Nodes.

ok, the Problem occured because there were some wrong settings - multiple gateways. So more than one default route was created. After deleting all but one out of the network the network started correctly.
