YANG Data Model for Bidirectional Forwarding Detection (BFD)
draft-ietf-bfd-yang-15
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).
Status of This Memo
This Internet-Draft is submitted in full conformance with the
provisions of BCP 78 and BCP 79.
