  "abstract": "This document defines extensions to the data-plane failure-detection protocol for Multiprotocol Label Switching (MPLS) Label Switched Paths (LSPs) known as \"LSP ping\".  These extensions allow a selection of the LSP to be used for the echo reply return path.  Enforcing a specific return path can be used to verify bidirectional connectivity and also increase LSP ping robustness.",
