Is MPLS/LDP enabled and up between the two boxes ? Notice the outgoing
"untagged" in the global LFIB on both boxes. I would have expected a
"imp-null" due to PHP
"sh mpls int <> int" on two boxes may tell you more.

Such a simple setup, but I just cannot figure out what's wrong.
Any feedback is highly welcome :-)
