The setup is one host with one bridge (bridge0), directly connected to another host with one brige. A GRE tunnel has been specified in OVS with the adjacent bridge as the remote IP. Assuming this is correct, why are the packets (ping etc.) that are sent between the host not encapsulated in GRE but ARP, Multicast etc are encapsulated?

The remote IP address of the tunnel should not be pointing at the
bridge interface that the tunnels are connected to. It needs to be the
IP address of the physical interfaces in the system, otherwise packets
won't actually be able to ingress into the bridge.
