Sure, sorry for the late reply. ovs-ofctl add-flow APPLE0 "table=0 priority=500 in_port=3 dl_type=0x8847 mpls_label=100 actions=pop_mpls:0x0800,1" ovs-ofctl add-flow APPLE0 "table=0 priority=500 in_port=3 dl_type=0x8847 mpls_label=200 actions=pop_mpls:0x0800,2"
I saw many refrences to doing this way in emails. if you see anything wrong let me know.
