For example,
(Host ip: 1.1.1.1) OVS1 gre remote_ip:2.2.2.2
(Host ip: 2.2.2.2) OVS2 gre remote_ip:1.1.1.1
If OVS1 wants to send a packet to OVS2 through gre tunnel, does it send the
packet to 2.2.2.2:<certain port>?
And when OVS2 receives a packet from 2.2.2.2:<certain port>, that means it
is a packet go through the tunnel.
Is that right? And what is the certain port?
