This example assumes openstack is at the other end of the mpls tunnels. -Packets generated and sent to port B are delivered to the MPLS domain infrastructure which will transport that packet to the other end -of the MPLS transport tunnel using the outer label. At that point, the outer label is decapsulated and the inner label is used to -select the destination openstack network. After decapsulation of the inner label, the resulting L2 frame is then forwarded to the -destination VM corresponding to the destination MAC. When the VM receives the packet, it is sent back to far end port of the traffic -generator (port B) using either L2 forwarding or L3 routing though the peer virtual interface. The return packet is then encapsulated -with the inner label first then outer label to reach nfvbench on port B. - -Only 2 MPLS labels stack is supported.
