Nope. Sorry. We always do identical single lookup. It is that some entries in the LFIB have mask (read: do not care bits). There are no two lookups nor two tables etc ... That's it. Trivial for anyone who has some min hardware design background :).

Go for it ! /* After all if we would have spend little cycles now and innovate tiny bit to improve MPLS data plane it would result in better operation and lasting longer .... ;-) */ Best, r.
