A packet that matched the flow entry is processed with normal switching. In that case, OVS behaves in the same way as a normal physical switch. > > Second, how does VLAN netowrk in OpenStack communicate with external > network? Using L3 agent in OpenStack? But how the OVS know where L3 agent is > and send the packet to it? Yes, Ryu plugin cooperates with L3 agent. The way that VMs communicate with an external network via router is the same as the method that a physical host communicates with an external network on physical LAN. > > Third, what does the external port in mac address based L2 isolation means? > From the documentation "Details of Ryu in cooperation with OpenStack > Grizzly", I see the term"external port" in both L2 broadcast case and L2 > unicast case. This is the port connecting to eth? The external port is a port which is not created by OpenStack, and it is connected to eth typically. The external port is used to connect OVS in the other host.
