I have tried that method using OpenFlow rules to implement VEPA. It may be easily supported to forward unicast packets. But I'm not sure how to set OpenFlow rules when transferring multicast packets. It's described as follows: Firstly, multicast packets from VM1 will be sent out by up-link netdevice and be loop backed to up-link netdevice by physical switch. Secondly, we should avoid multicast packets being sent to VM1. Here we need to gather every VM MAC addresses and add rules for each VM. Could you share with me some opinions on such problems? B.R.
