28# TEST RFC 4182
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
