This document describes a typical use case of MPLS-TP, where signal degrade defect needs to be correctly detected and transmitted via OAM messages within network. When MPLS-TP evolves to Segment Routing MPLS, transit node has no knowledge of labels to be encapsulated in MPLS label stack. Transit node cannot spread OAM messages with signal degrade defect indication. Thus, a solution is proposed in this draft.
