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
