             Homenet profile of the Babel routing protocol
                  draft-ietf-homenet-babel-profile-06

Abstract

   This document defines the subset of the Babel routing protocol and
   its extensions that a Homenet router must implement, as well as the
   interactions between the Home Networking Control Protocol (HNCP) and
   Babel.

1.  Introduction

   The core of the Homenet protocol suite consists of the Home
   Networking Control Protocol (HNCP) [RFC7788], a protocol used for
   flooding configuration information and assigning prefixes to links,
   combined with the Babel routing protocol [RFC6126bis].  Babel is an
   extensible, flexible and modular protocol: minimal implementations of
   Babel have been demonstrated that consist of a few hundred lines of
   code, while the "large" implementation includes support for a number
   of extensions and consists of over ten thousand lines of C code.

   This document consists of two parts.  The first specifies the exact
   subset of the Babel protocol and its extensions that is required by
   an implementation of the Homenet protocol suite.  The second
   specifies how HNCP interacts with Babel.

1.1.  Requirement Language

   The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",
   "SHOULD", "SHOULD NOT", "RECOMMENDED", "NOT RECOMMENDED", "MAY", and
   "OPTIONAL" in this document are to be interpreted as described in RFC
   2119 [RFC2119].

1.2.  Background

   The Babel routing protocol and its extensions are defined in a number
   of documents:

   o  RFC 6126bis [RFC6126bis] defines the Babel routing protocol.  It
      allows Babel's control data to be carried either over link-local
      IPv6 or over IPv4, and in either case allows announcing both IPv4
      and IPv6 routes.  It leaves link cost estimation, metric
      computation and route selection to the implementation.  Distinct
