[Openstack] br-tun and br-int bridges in Neutron OVS

2014-04-24 Thread HS
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
