Hi Dear All, I have a question about the ovs-ofctl command line to add flow.
What I want is that, assume that I have 4 vms (H1, H2, H3 and H4) connecting to the same bridge. when H1 send a packet for H2, I want it also forwards to H4. I can append the H4 output port to the actions output ports but I dont want to use the ovs port to do that since it only works in the single OVS environment. When I have two OVS, OVS1 can not know the output port of OVS2. Thus, I wondering that can I do like this as below: First forward the packet just based on the layer 2 learning swtich, forwarding the packet to the destination where it should do, like H2 in the previous example, and then, rewrite the des_ip on the packet and forward it based on the des_ip again (for example, H4 ip address). Because using IP address, I do need to worry about the port across different OVS (all OVSs are connected through tunnel. All VMs are in the same subnet even they are located on different servers.) If the CLI can do this, that would be really great, or I have to use the openflow controller. Thanks very much for any comment.
