Hi, When OVS plugin is used with GRE option in Neutron, I see that each compute node has br-tun and br-int bridges created.
I'm trying to understand why we need the additional br-tun bridge here. Can't we create tunneling ports in br-int bridge, and have br-int relay traffic between VM ports and tunneling ports directly? Why do we have to introduce another br-tun bridge in between? Thanks, -hs
