Halo ,

IPv6 is related to MPLS in the same way as IPv4 ( i.e it is another network
protocol transported on top of MPLS ). In that sense IPv6 is
used with MPLS but not instead of. Please note that the IPv6 flow label has
dissimiliar meaning than MPLS label and shall be used to diffrentiatate
flows along with source and destination address ( see RFC3697 ) .
