A service provider's core network utilizes OSPF as the IGP and LDP for label distribution. An engineer adds a new PE router, PE3, which successfully establishes OSPF adjacencies and LDP sessions with its neighbors. However, PE3 is unable to build a label-switched path (LSP) to the remote PE1 router. The command `show ldp session` on PE3 confirms an active session to PE1's loopback address (192.168.255.1). Despite this, the `show route table mpls.0` output on PE3 is empty. Which of the following is the most likely cause for this issue? ```mermaid graph TD PE1(PE1 lo0: 192.168.255.1) -- P1(P1) -- P2(P2) -- PE3(PE3 lo0: 192.168.255.3) ```
