Thank you, that was exactly what I was looking for. I have set up OSPF with BFD on both nodes, so the service is up and running and seems to communicate with each other, but I still loose internet when disconnecting WAN on the master node, so there is no rerouting to node 2 and I am trying to figure out what may be wrong. First of all, is it sufficient for me to use OSPF with BFD or do I need to setup BGP to achive this? This is only for a small homelab, so I am not trying to make this more complex than necessary and I understand BGP can be quite complex.
