[j-nsp] Junos labeled-unicast announces unusable routes, certainly this is a bug

No, it isn't.

Junos BGP is announcing routes it knows, for sure, are invalid.  It
knows that because BGP is making up a wrong label (2^20-1) because it
hasn't allocated one, and it can't announce the route without a label.
 This is an inexcusable bug that is very far from "working as
designed."

The documentation is wrong, you cannot configure both AFI=1 SAFI=1 and
AFI=1 SAFI=4 on the same BGP session.  If it worked as documented, the
above behavior would not happen, and AFI=1 SAFI=1 would be available
to use for these routes.  That is not the case.
