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[6].ip[6].forwarding, enable net.mpls.forwarding 32 # Use IPv6 between R1-R2-R3 and IPv4 between R3-R4 33 # As we use IPv4 on last link we should use only expl.null there 34 # because implicit null will assume IPv4 (as the next-hop) 35 # But we can use impl null on R2-R1 link because stack will correctly 36 # guess IPv6 (from next-hop) 37 # Add route on R1 in order to encapsulate into MPLS the IP6 packets with 38 # destination equal to R4 right hand side interface 39 # Add MPLS routes on R2 in order to forward frames belonging to that FEC to R3 40 #
