<div dir="ltr"><div><div><div>Hi,<br><br></div>When OVS plugin is used with GRE option in Neutron, I see that each compute node has br-tun and br-int bridges created.<br><br></div>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?<br>
