Need to build a network with MPLS + RSVP + unnumbered interface.
The link shows as Down.
Check if unnumbered interface is used. If yes, then this is the expected behavior.
If a topology requires configuring unnumbered interfaces, ensure the following configuration is committed:
set protocols ospf traffic-engineering advertise-unnumbered-interfaces
Once this is configured and committed, the links will come up. For more details, refer to the technical documentation on traffic-engineering (OSPF) .
