  29 # Setup four routers connected like this: R1---R2---R3---R4--
  30 # Goal is to be able to ping from R1 the outermost interface of R4
  31 # Disable net.inet.ip.forwarding, enable net.mpls.forwarding
  32 # Add route on R1 in order to encapsulate into MPLS the IP packets with
  33 #     destination equal to R4 right hand side interface. Use two labels here:
  34 #     25 and IPv6 Explicit NULL
  35 # Add a double tagged MPLS route on R2 in order to forward frames belonging to
  36 #     that FEC to R3, with IPv4 NULL being the most outermost one
  37 # Add MPLS "POP" route on R3 for that FEC, pointing to R4
  38 # Do the same for the reverse direction (R4 to R1)
  39 # ping from R1 to R4 right hand side interface
