                 draft-ietf-babel-information-model-03

Abstract

   This Babel Information Model can be used to create data models under
   various data modeling regimes (e.g., YANG).  It allows a Babel
   implementation (via a management protocol such as netconf) to report
   on its current state and may allow some limited configuration of
   protocol constants.

1.  Introduction

   Babel is a loop-avoiding distance-vector routing protocol defined in
   draft-ietf-babel-rfc6126bis [rfc6126bis]. draft-babel-7298bis
   [BABEL-HMAC] defines a security mechanism that allows Babel messages
   to be cryptographically authenticated, and draft-babel-dtls
   [BABEL-DTLS] defines a security mechanism that allows Babel messages
   to encrypted.  This document describes an information model for Babel
   (including implementations using one of these security mechanisms)
   that can be used to created management protocol data models (such as
   a netconf [RFC6241] YANG data model).

   Due to the simplicity of the Babel protocol, most of the information
   model is focused on reporting status of the Babel protocol, and very
   little of that is considered mandatory to implement (conditional on a
   management protocol with Babel support being implemented).  Some
   parameters may be configurable; however, it is up to the Babel
   implementation whether to allow any of these to be configured within
