The requirements for Lock Instruct (LI) and Loopback (LB) in the Multiprotocol Label Switching Transport Profile (MPLS-TP) are specified in [RFC5860], and the framework of LI and LB is specified in [RFC6371]. A Label Switched Path (LSP) that is locked, using LI, is prevented from carrying user data traffic. The LB function can only be applied to an LSP that has been previously locked.

GMPLS RSVP-TE Extensions for Lock Instruct and Loopback
This document specifies extensions to Resource Reservation Protocol - Traffic Engineering (RSVP-TE) to support Lock Instruct (LI) and Loopback (LB) mechanisms for Label Switched Paths (LSPs). These mechanisms are applicable to technologies that use Generalized MPLS (GMPLS) for the control plane.
