How are the LERs determined in an MPLS LSP using LDP

At this point IGP is fully converged (OSPF with all interfaces in area 0 for simplicity) and MPLS is enabled on all interfaces using LDP. No BGP configuration exists at this point. … Once the network is fully converged with IGP and LDP exchanges are completed, does a PE router then look through the FIB (or is it IGP RIB?) …
