      YANG Data Model for Bidirectional Forwarding Detection (BFD)
                         draft-ietf-bfd-yang-17

Abstract

   This document defines a YANG data model that can be used to configure
   and manage Bidirectional Forwarding Detection (BFD).

   The YANG modules in this document conform to the Network Management
   Datastore Architecture (NMDA).
