A conceptual question. Lets say you have MPLS Core running LDP in all the links and now you deploy TE tunnels. On the control plane RSVP will signal a path from headend to tailend as per TE operation, however on the data plane a particular router along the tunnel path will construct its LFIB taking into account both RSVP learnt label and LDP learnt label(s).
Is there a built-in mechanism that prefers RSVP labels over LDP ones and does not permit LDP label to enter LFIB if RSVP label exists?
If not, I would imagine that this will create a mismatch between control and data planes and undermine the whole purpose of TE tunnels...
