Not sure what to make of your picture after it goes through

So something like
CE---PE1----PE2---P---( cloud )
^ ^
cust PE |
agg PE

If you're talking a vrf-lite-like scenario, then that means packets
are going from PE1 to PE2 unlabeled. If that's the case, they'll
follow the default route just like any other route. If you're talking
about label exchange of some sort between PE1 and PE2, there's a few
ways you can do that; we'd have to talk about more specifics, but in
general there's no provisions that a default route is treated
differently than any other route.
