If you add multiple output actions, it simply means that the packet is duplicated.
You could rewrite the address to be a multicast address, and you can create flow table entries that act on multicast addresses, but there's no "built in" support for multicast in the OpenFlow 1.0 spec. Of course, a switch may have its own multicast behavior outside of OpenFlow, but that's up to the switch. Hope that helps. -- Murphy On Jul 12, 2012, at 1:08 AM, Qingyun Zuo wrote: > Hi, > Does OpenFlow switch support multipath unicast? or multicast? > When I edit a flow entry, I add two egress ports to the ACTION, is it > multicast? > > -- > Best Regards > Zuo Qingyun >
