Hi,
Thank you. But if it does not have IP Ethertype, if I use the
commands
ovs-ofctl add-flow br0 "in_port=2,priority=0,actions=output:1"
ovs-ofctl add-flow br0 "in_port=3,priority=0,actions=output:1"
i.e without specifying the IP address, it should work, right? But that too is
not working. Can you please help me to define the ARP rules?
Thank you
