Hi Serguei, The Match is on IPv4 packets (type 0x800) and the action is to add a MPLS header to the packet. I'm pinging from h1 to h2 so the first packet that reaches s1 has a Ethernet header and a IPv4 header. The output should be the same packet with a MPLS header between the IP and Eth headers. However the packet simply disappears.
