# Test MPLS encap/decap and forwarding using INET6 as encapsulated protocol
# Setup four routers connected like this: R1---R2---R3---R4--
# Goal is to be able to ping from R1 the outermost interface of R4
# Disable net.inet6.ip6.forwarding, enable net.mpls.forwarding
# Add route on R1 in order to encapsulate into MPLS the IP6 packets with
#     destination equal to R4 right hand side interface
# Add MPLS routes on R2 in order to forward frames belonging to that FEC to R3
# Add MPLS "POP" route on R3 for that FEC, pointing to R4
# Do the same for the reverse direction (R4 to R1)
# ping6 from R1 to R4 right hand side interface
#
# redo the test using IPv6 explicit null label
