No, I don't want a host to host tunnel, I want to create a NVGRE so the tunnels are between host an ovs port.

No, my problem is I can't modify external switch so I try to create a new network based on tunnels (NVGRE) that are connected with OVS port and handle packages to ryu controller. You are right, Ryu does not need to handle GRE, Ryu see them as simple packages because OVS transform GRE bridge packages to simple packages that are sent to ryu. I partially solve my problem, that was a wrong configuration in the host. I created a IP Gre tunnel in host but OVS create a Ethernet Bridge Gre Tunnel for port, so when I flood package with Ryu host doesn't know how to deal with this data package. So my solution was set Ethernet Bridge Gre Tunnel in host and now packages are send with a correct format but I am loosing ARP response so I will check my host configuration.
