  28 # TEST MPLS encap/decap and forwarding using INET as encapsulated protocol
  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
  34 # Add MPLS routes on R2 in order to forward frames belonging to that FEC to R3
  35 # Add MPLS "POP" route on R3 for that FEC, pointing to R4
  36 # Do the same for the reverse direction (R4 to R1)
  37 # ping from R1 to R4 right hand side interface
