#
# 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.inet[6].ip[6].forwarding, enable net.mpls.forwarding
# Use IPv6 between R1-R2-R3 and IPv4 between R3-R4
# As we use IPv4 on last link we should use only expl.null there
# because implicit null will assume IPv4 (as the next-hop)
# But we can use impl null on R2-R1 link because stack will correctly
# guess IPv6 (from next-hop)
# 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 expl.null 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
