description:
Add another simple MPLS test but using this time a mixed IPv4/IPv6 LSR
This test encapsulates IPv6 packets, pass them over MPLS to an IPv6
neighbour that switches label and passes forward to an IPv4
neighbour. There, the IPv6 packet is decapsulated and passed to IPv6 stack
For the return path we test both implicit and explicit null encapsulations

+# 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
