                      YANG Data Model for LSP-Ping
                 draft-zheng-mpls-lsp-ping-yang-cfg-09

Abstract

   When an LSP fails to deliver user traffic, the failure cannot always
   be detected by the MPLS control plane.  RFC 8029 defines a mechanism
   that would enable users to detect such failure and to isolate faults.
   YANG, defined in RFC 6020 and RFC 7950, is a data modeling language
   used to specify the contents of a conceptual data stores that allows
   networked devices to be managed using NETCONF, as specified in RFC
   6241.  This document defines a YANG data model that can be used to
   configure and manage LSP-Ping.

1.  Introduction

   When an LSP fails to deliver user traffic, the failure cannot always
   be detected by the MPLS control plane.  [RFC8029] defines a mechanism
   that would enable users to detect such failure and to isolate faults.
   YANG, defined in [RFC6020] and [RFC7950], is a data modeling language
   that was introduced to define the contents of a conceptual data store
   that allows networked devices to be managed using NETCONF [RFC6241].
