When OVS plugin is used with GRE option in Neutron, I see that each compute <br>


node has br-tun and br-int bridges created. </font><font face="serif" size="3"><br>


</font><font face="Verdana" size="2"><br>


I'm trying to understand why we need the additional br-tun bridge here. <br>


Can't we create tunneling ports in br-int bridge, and have br-int relay <br>


traffic between VM ports and tunneling ports directly? Why do we have to <br>


introduce another br-tun bridge? </font><font face="serif" size="3"> </font><br>
