LSPs formed by LDP normally follow IGP routing. The LDP speaker selects the downstream LSR for a particular prefix as

This feature allows users to preserve IP TTL and MPLS EXP (also known as TC) value on MPLS routers, as well as add a user-specified TTL/EXP value when pushing new MPLS labels in pipe mode. With the added pipe mode support, packets can traverse the network such that only the LSP ingress and egress nodes are visible to the end users and the MPLS core network can be hidden from the end user.
